Reprise: Layer 2 and 3 troubleshooting problem and solution?

[Chuck Larrieu]

Got an even better one for you all to ponder.

Routers have been off line for a few days. Last thing I did on them was
write erase configs so I could rebuild them for a certificationzone CCNA lab
for which I was doing a technical review. This was a frame relay lab, and
had no routing protocols involved nor configured.

In any case, I was about to make the pod public, to prove to some who have
asked, that indeed ip routing was not working. I did a write erase and a
reload of the router that had been the frame relay switch in the lab review.
Configured ip and routing. Low and behold - ip routing is working. All
routes are appearing as they should.

I quickly move the serial cable to the other serial interface on either
router, reconfigure, and ip routing is still working.

Ok. I add the third router into the mix, and ip routes are all appearing!

I should add that prior to doing the frame relay lab review, i.e. before
blowing the routers away to eliminate debris that might effect this review,
I had the routers off for a day or two. I checked prior to the blowout, and
ip routing was definitely not working at that point.

So now I am in the rather interesting position of questioning my sanity
again. This phenomenon is driving me nuts. It's kinda like the old
experiments in brainwashing - everyone in the frat house decides to blow
Joe's mind by telling him what a great blue shirt he's wearing, when he is
really wearing green. After a few hours of this, Joe doesn't know what to
believe any more.

Neither do I.

Subject:Trying once again: Layer 2 and 3 troubleshooting problem

Now that it appears I can post again, let me try this again. Discovered the
problem Saturday. Have not been able to ask for help.

Got a good one for you all to ponder.

I am in the process of reassembling my lab. Routers have been off line for a
couple of weeks. Friday I brought two back on line to test some
configurations for someone. Discovered that I was unable to route.

Here is what I know:

Serial interfaces on both routers are up. I know this because:

1) Show CDP neighbor reveals the other router, both interfaces, both routers
2) Debug serial interface and debug serial events shows communication across
the interfaces
3) Show interface reveals the interface is up and the protocol is up, both
interfaces, both routers
4) On either router I can ping the directly connected interfaces of the
other router
5) Oh, and IPX and AppleTalk routing work just fine. I see all networks for
both protocols.

I also know that the routing protocols are set up correctly. Honest, gang.
I'm not sure how many more ways I can check an IGRP configuration with one
network in it. Let alone EIGRP and BGP ( the lab configuration I was
testing ) Besides, as I stated, I can ping the each router serial interface
from the other router.

I also found that one time, if I reloaded with an empty startup config, and
configured from the setup, that I would have routing. Admittedly I have not
done too many more experiments along this line.

Oh,  one last thing. IP routing works fine and dandy across the ethernet
interfaces. I.e if I plug both router  ethernets into the same hub, routing
is great. Even the BGP processes establish neighbor relationships with the
right information..

Well, I'm frustrated as hell. And out of ideas. I have gone so far as to
reload images into the routers. The only other thing that is a wild guess is
that two of the three routers were the recipients of new images via Cisco's
Router Software Loader. But the other one was updated the old fashioned
way - TFTP. Makes no sense to me that this would effect the ability of the
IOS to see the serial ports. I suppose strange things have happened.

I do find it rather incredible that every serial interface on every single
one of my routers has failed at exactly the same time. And failed for IP
only.

Anyone have any ideas? Is there some secret command within IOS version 12.x
that someone is keeping secret from me? I continue to search on CCO, but CCO
is hiding this secret well.

Chuck

RE: Sample Question Question

[Cthulu, CCIE Candidate]

Hey, gang,

That was a good one!   It's been a year since I took my last CCNP exam, but
I do believe that I improved my score by watching the wording.  Host address
vs. network address vs. subnet address mixed with classless or classful, add
a pinch of subnet zero, and oh, wait, let's use DLSW+!!!  Well, needless to
say, I know some engineers that are brilliant in the real world, but missed
points due to their overquick reading of a question.  

Raymond, thank you for including me the group that you did...I am highly
complimented!  

By the way, I am moving from Germany  to Texas in a few weeks.  My new
contributing address will still appear as "Cthulu, CCIE Candidate", but will
be homed on [EMAIL PROTECTED]   ( I don't know why, but the works
of H.P. Lovecraft seem appropriate literature for studying Cisco...is that
just me?)

Take care,

Charles

Hi Michael, Daniel, Charles, Duarte, Bal, Sanjay, Chuck, Lou, Aaron, Sam,
Oz...

I've learned two things from this (seriies of) question(s).
#1:People would MUCH rather talk about meat/potatoes of tech
questions
than some of the off-subject crap that gets thrown into this
discussion
group; and
#2:There are some genuinely nice and interested people out there.

This question raises the paradox which we face when taking the CCIE written,
and then evaluating how to handle a lab scenario:  I don't have enough
information
to answer completely.  Please let me explain

Everyone agrees that the answer is "e. none of the above".   Review the
provided

answer all the way at the bottom.  Under normal circumstances (with no
consideration for zero subnet-enable)  the statement is correct, this
would
be
an illegal address/mask pair.  But, considering the possibilites of the
world,
I don't see a thing wrong with 193.243.12.43/25. ... and I would have been
totally messed up by that statement.

... which is why Sanjay and Michael and, of course Chuck are getting close
to
being ready for the lab. attention to detail the "Spot the Issue"
gotcha
in
the config with this scenario is a single line of code:  zero subnet-enable

btw:  Chuck Larrieu wins hands down for his completely awesome explanation
of
how to figure out what evens have in common, and what odds have in common.
After that, it's a simple matter of understanding inverse masking DOH!

Thanks a million, you're a fine bunch.

RE: 2500 Series & FLASH PMCIA...

[Bob Worrell]

The PCMCIA slot is for upgrading the routers.
I've never used this method to upgrade them nor heard of any part
number/image you can order/download from Cisco to use this upgrade method.
Download a new version of IOS and upgrade/boot the router using tftp.

Besides, the case doesn't fit on most 2500 models after inserting the PCMCIA
flash memory.  (Curiosity got the best of me a couple of years ago.)

Re: Logon to NT Server?

[Adam Hickey]

Correct me if I'm wrong...
 
Microsoft OS's use broadcasts to find the PDC. 
Routers will not forward broadcasts. Therefore you will need to use a 
helper-address to convert the broadcast to a unicast address.

RE: VLAN.

Gunjar,

Yes you can separate broadcast domain's with VLAN's.  The process is pretty
much what networking is all about.  IF you are able to get the Cisco Press
book, Cisco LAN Switch Configuration ISBN 1-57870-094-9.  The book is well
written, easy to follow, and will explain a lot.

Good luck networking.

RE: Logon to NT Server?

You either need to enable WINS on the NT server or 
setup a LMHOSTS file to tell the clients on LAN 2 where to find a domain 
controller.  I will leave it up to you to find information on setting up 
WINS or LMHOSTS files.
 
I would also recommend that you only send a message

2500 Series & FLASH PMCIA...

[Circusnuts]

 
Has anyone dealt with 
this...  I have a bunch of 2500's in my home lab & I realized that my 
2512 has a FLASH Card "port" on the motherboard.
 
Any ideas for the 
workable part #'s (I did comb the CCO to no avail)
 
Any experiences ???  
I did see a few references to IOS complications (that was used in the context of 
what "feature pack" you were installing), & can I run a regular FLASH 
stick with the PMCIA card (to make 16 megs FLASH)...
 
Thanks !!!

Which access-list increase load the most?

[K.FUJIWARA]

Hi, all.

Though the null interface is the best solution for load in the ruter
CPU, which
extended / standard access-list is the best to reduce the load?
Extended one's result may be depends on where it will be put or the
case, so where
should it be configured? Destination?
If you have some good examples, please show me.

And then, do you know good tools or utility to monitor the routers
performance on
CPU or RAM in real time?

Limiting bandwidth on an IP address?

[Russ Kreigh]

Hi all

I would like to limit an IP address on our network to 256k, the reason is
because they have internet access and I dont want them to use up all the
bandwidth, I dont want to dedicate the bandwidth, just put a limit on the
maximum they can use, I have looked several places and have tried some
things, but they all seemed really difficult and I didnt think something
like this should be that complex, so if someone can help me out it would be
appreciated.

Thanks in advance

Re: Redistribute Static

[Michael Fountain]

The only static route that is redistributed into the routing protocols by 
default is the default route.  And, I know that is true for RIP, you'd have 
to look and see if it were true for other routing protocols also.

If you want other static routes to be advertised you have to use the 
redistribute static command.

hope that helps

FTP Access Lists

[Rowe, Justin]

Has anyone got a config for working access-lists for FTP and FTP data

I'm able to establish a connection for FTP, but can't get any data. The
client is using FTP-passive mode.

The FTP server at client end is configured only for outbound only

Upon doing logging found that 102 denies ftp packets above 1024

I've tried various changes to the config, but with no luck

101 is for Inbound
102 is for Outbound

access-list 101 permit tcp any eq ftp host x.x.x.x established
access-list 101 permit tcp any gt 1023 host x.x.x.x established

access-list 102 permit tcp host x.x.x.x any eq ftp
access-list 102 permit tcp host x.x.x.x any gt 1023

Thanks

I'm gonna have to disagree with that statement. At least in part. The MAU

Ports 1 and 8 on a MAU are reserved for ring in and ring out for daisy

Subject: Re: Token ring question - Solved!


Don't you hate it when your trying to set up a Layer 3 scenario, but you get
stuck troubleshooting Layer 2 problems!?!?!?!

Thanks to everyone who posted and emailed suggestions.  Everything is
working now.  Some info that I probably should have included in the first
post was that I was plugged into Ports 1 &2 on the MSAU (but I also tried
Ports 7 & 8), and that the MSAU was giving a clicking sound in synch with
the routers giving debugging info - about once every 10 seconds.  Also, I
had tried each router individually and got identical results, and there are
no other stations plugged into this MSAU.

Basically, all I did to solve it was plug the cables into ports 3 & 4 on the
MSAU, and walk away for about an hour.  When I came back we were UP and UP!
I have since plugged the cables back into ports 1,2,7,and 8 and verified all
are working.

I'm guessing that either the ports were stuck (and they auto-reset
themselves - Is that possible?), or perhaps I just didn't push those type 1
connectors in far enough.  If there's any Token Ring gurus out there that
would like to post about what could possible cause a port to become stuck,
or if it's possible for them to auto-reset, I'm sure everyone would
appreciate it.

Thanks again for all the replies!  This list rulz!

RE: Logon to NT Server?

[Dave Hennen]

the key will be 
being able to identify the domain controllers by name, name resolution.  if 
the pc can't find the domain controller, PDC or BDC in nt4, your pc will not be 
able to logon and you see the message you got.  if the controller is on a 
remote network and you are using tcpip your pc needs to know the address of 
the domain controller before making the logon request.  not much needs to 
be done on the routers excepts making sure the netbios related ports are not 
blocked, 135-139 or something like that.
 
this can be done 
in a couple of ways, a local file called lmhosts, which is a static listing 
of ip addresses and computernames kind of like a hosts file in a unix 
environment.  the second is to setup wins resolution, which is a service 
that dynamically builds a database of computernames and their tcpip 
addresses.  this requires a server be running the wins service and a 
setting in the client pc TCPIP properties.  a third way is to put a Backup 
Domain Controller on the remote subnet

This is true. "Reasonable" is not at issue here; your options are a) do it
Cisco's way whether it's reasonable or not, or b) don't do it at all.

Re: Link Flapping

[John Neiberger]

Route flapping is simply a route that keeps going up and down.  Regardless
of routing protocol, participating routers will continuously have to update
their routing tables to account for the changes.  If the route doesn't
stabilize, this can seriously affect the CPU usage levels on your routers,
depending on your choice of routing protocol and the size of your routing
table.

Specifically regarding convergence, route flapping will not allow the
network to truly converge since it's in a constant state of flux.  You must
find ways to deal with this or your network could become quite unstable when
routes start flapping.  This really depends on several factors, but you get
the idea.  I hope that clears things up a little bit.

Re: Who wants to be a CCIE... Challenge Question

sorry i don't see why you HAVE TO have 'ip classless'
as the networks are all full class C's (or maybe only
subnets of full class A's as they are 10.x.x.x??!!).
anyone else wants to clarify/confirm? :)

Re: OSPF !!!

[Olumuyiwa Alao]

I agree Cost affects route selection and Priorty affects the selection of a
DR.

Why do you have "default-information Originate." in your config for  2
routers?. The reason for this command is if one of your router is learning a
default route from it's side of the network or from another routing process
and injecting it into the OSPF domain. With this command in two routers, you
are basically injecting a default route from 2 sources that are in the same
area. I do not think you want to do that.

The command "default-metric" is only useful when you are redistributing
multiple routing process into OSPF and you want all routes learned from all
this process to be injected into OSPF with the same cost. I do not think you
need the command. OSPF assigns a value of 20 within its AS. The command is
useless unless this router is an ASBR

The command distance 85 is not neccessary unless you have another routing
process that has a lower administrative distance than that of  OSPF (example
is EIGRP 90 for internal and 170 for external) and you want OSPF to be used.
This command is used when you want to change from one routing process to an
other while minimizing downtime. So you keep both processes running and
later remove one.

I hope I have been helpful. IfI am wrong, kindly let me know.

Cost does affect route selection. OSPF injects routes to routing
table based on costs. If there are multiple paths to a destionation,
the least cost path will be selected.

Pirority only affects desinated router election. Desinated router is the
router speaks for the multicaccess network about the attached network
links.  Priority has nonthing to do with route selection.

RE: Layer 3 switching vs. Layer 4 switching?

[Francisco Muniz]

I would think the process of directing to the lest loaded server would be
higher in the stack than level 4. Except that the Alteon uses some statefull
firewall like table where it remembers the sessions going in to each server,
it would probably work best if all the servers are of alike power, wouldn't
it? Also, most applications that need a certain QoS would need higher layer
switching, as L3 alone won't cut it.

RE: Token ring question - Solved!

[David B McGlumphy]

Ports 1 and 8 on a MAU are reserved for ring in and ring out for daisy
chaining MAU's.  You cannot use them for stations.

Subject: Re: Token ring question - Solved!


Don't you hate it when your trying to set up a Layer 3 scenario, but you get
stuck troubleshooting Layer 2 problems!?!?!?!

Thanks to everyone who posted and emailed suggestions.  Everything is
working now.  Some info that I probably should have included in the first
post was that I was plugged into Ports 1 &2 on the MSAU (but I also tried
Ports 7 & 8), and that the MSAU was giving a clicking sound in synch with
the routers giving debugging info - about once every 10 seconds.  Also, I
had tried each router individually and got identical results, and there are
no other stations plugged into this MSAU.

Basically, all I did to solve it was plug the cables into ports 3 & 4 on the
MSAU, and walk away for about an hour.  When I came back we were UP and UP!
I have since plugged the cables back into ports 1,2,7,and 8 and verified all
are working.

I'm guessing that either the ports were stuck (and they auto-reset
themselves - Is that possible?), or perhaps I just didn't push those type 1
connectors in far enough.  If there's any Token Ring gurus out there that
would like to post about what could possible cause a port to become stuck,
or if it's possible for them to auto-reset, I'm sure everyone would
appreciate it.

Thanks again for all the replies!  This list rulz!

Let's not forget the 2510/2512. I got my 2510 for

Re: ISDN Configuration - Help

[Raymond Everson (Rainman)]

Aziz, Light! (Sorry, it's from "The Fifth Element" and I couldn't help it)

First, the easy one:
If you don't want RouterB to be able to dial to RouterA, simply do not define
interesting traffic (am I missing something?)
Second (the linear thinker in me) (Assuming Q.931 & Q.921 are cool)
Remove auth. altogether; does the int complete the call?
Next (progressive jazz):
Eliminate "Ppp pap sent-username RouterB password cisco2" from the BRI0
interface on RouterB; with debug dialer & debug ppp neg, what's going on?
(btw:  doophus question of the day:  what's "debug ppp auth" ?
I think your passwords are bass-ackwards.  On RouterB, I think you wanna
put "Ppp pap sent-username RouterA password cisco1" and vice-versa on
RouterA.

Remember the words of the venerable Bruce Caslow "It's always TWO
things; (1) What to do; and (2) What to look for"

Please let me know if this works 'cause I can't call out to another ISDN-
Connected router  (unless you want to work a few things out together!)

Rainman

RE: CCNA, but it isn't helping...

[Trevor Corness]

I agree with Oz's response.. you should take the Win2000 rollout, and plug
around a little.. talk to people.. network PEOPLE, and create contacts.
They may help you sometime down the road.  It is a tight community, you
never know when you're going to run into someone again, probably on the job.
Don't burn bridges in this industry, build them.

Myself, I'm JUST starting out (NO real world experience).  I interviewed
this morning with a VERY young startup here in Vancouver (their webpage only
went LIVE yesterday morning, with a v1.0 final product).  From what was
said, it seems if I get the position, I'll start out in Tech Support
Helpdesk kind of stuff, but grow to LAN Server and Router/Switch Admin.
Maybe look to find a startup like this in your area (Vancouver is full of
them, as are other hightech booming places), they offer a great opportunity
to move around, and build that Network Admin resume up quickly (plus the
stock options are always nice )

Take the rollout of Win2K, and meet people in the field.. ask them how they
got started.. let them know you are looking.  They may just give you a call
someday, when they are looking for someone.  This industry is 10% what you
know, 90% who you know.  So get out there, and learn some names and people!

Hey Group,
Sorry to bother you on this non-technical question. We all know that
when
you send your resume out to companies that are asking for cisco
professionals, that they want someone with experience. I have been in the IT
field for about 2 years (rookie) doing deskside. I decided to start on the
Cisco side of things and recently obtained my CCNA. I am now going for my
CCDA and so on... My question is, if all of these companies are looking for
experience, then how do I get started on getting it if nobody will hire just
a certification? Don't get me wrong, I know my stuff, and at a recent
interview I answered all of the tech. questions to a T. I am starting to
doubt myself and am actually, probably, going to sign a contract for a
windows2000 rollout. I don't mind doing this because it will put Win2000 on
my resume but I was kinda hoping to start off in a new direction (cisco).
Should I just keep on studying for higher cert.'s and just hope I get a
lucky
break, and is that what it's all about...a lucky break? Thanks for the help
group...any comments are appreciated.

RE: Microsoft 'Routers'

[Cohen, Michael]

I have seen Unix, Novell, and Microsoft boxes route in a functional network
many times.  This is certainly a viable solution for routing (depending on
the exact router functions, size and design of the network) however I've
usually used PC's running routing protocols not to route, but to choose the
best router for a destination when multiple paths exist on an IP network and
you don't want to send  traffic to one router and then be rerouted back
across the same network.  This allows more efficient bandwidth usage on that
network however it could cause a problem in OSPF with SPF computations if
those boxes "flap" or get turned off frequently.  That's why I've only used
routing protocols on servers that should normally be up and active.  Proper
area design (link-state) and route filters (distance-vector) should of
course be implemented regardless however are extremely important when using
additional devices like PC's in the routing domain.

What do you exactly mean by 'functional' ? Have you seen it working in
a live network ?
Unix for example, has provided more routing resources and it doesn't
seem to be a viable substitute for a router device.
Would Microsoft suggest to use the server as a router only ? The cost of a 
PC would be much more expensive than a Cisco 25xx...

RE: Career Advice

[Poyerd, Denis]

Depends if you're married or not. Most of the material for CCNP/CCDP can be
self-study but would highly recommend using mentorlabs' vLabs
(www.mentorlabs.com). Also, you might try to get into the BCRAN course as it
is a unique opportunity to understand internet technologies. Regardless, I
think it is highly feasible to get CCNP certified within a year.

As far as hardware, you "might" want to invest that in the vLabs if your
funding is limited. They are more diversified and challenging.  

As far as the job, don't know. Depends if your married and solely
financially liable. Usually recommend getting into the environment as early
as possible.

Hi all,
I have my CCNA, CNA and MCP-TCP/IP. I've been in the industry for
about 2.5 years mostly system admin. The situation at my contract
house was conducive to my leaving and really putting forth the effort
to start my new direction. I've been trying to get my foot in the door
of network infrastructure but no dice, I was offered a job starting
Monday if I could install routers solo but I hate making a fool of
myself ;-)
I'm not discouraged nor bitter but would like my plans evaluated by
those in the know.
I've been offered another contract admin position that is in 3 month
increments. I figure I'll bite the bullet and continue in this role.
I'll pick up some more hardware for a home lab (currently working half
a dozen machines networked NT). With that equipment and a lot of books
I'll pursue my CCNP.
With that in mind, a few questions:
1) Does it seem feasible for a reasonably disciplined home student to
obtain CCNP within a year? Six months? Is it worthwhile, and again
feasible, to pursue CCDA simultaneously (that is, will the material be
related enough as to not distract from each other)?
2) Are there specific hardware units which are typically more
conducive to my home study goal? Or should I just keep my eye out for
used equipment and then evaluate the units as they become available.
Up to a thousand dollars (U.S.) seems doable.
3) How best to enter the field. Join a large company, as an admin,
with the necessary infrastructure and the hope of transferring to
networking? How about Cisco themselves, do they ever take entry level
personnel?
4) Finally, and really reaching, say in one year I'm on the network
team, achieved my real world experience and certification goals. From
that point would it be reasonable to put a 5 year target on a shot at
CCIE? Again assuming hands on work and home study. I know CCIE is tops
and am wondering if those obtaining such are in the field 5 years, 10,
etc. 
5) Should I take the aforementioned contract job as admin or hold out
for what I really want? I figure I can sit at home for a couple weeks
more before going nuts.

I realize all the questions can be subjective, just trying to set
realistic time frames for my goals.

Thanks for any, and all, advice.

all machines including the workgroup computers must be configured with the wins you
are using on the domain

the computers in the workgroup shloud appear in the net hood under the workgroup
name in the microsoft network portion of net hood

I have seen this before and it takes a while to heal . One thing you can try in the

other side and it should find it .I hope i have added somthing you have not tried .

Re: Firewalls

[Kent]

David,

I have a question, as I understand that Checkpoint is
a software based firewall, right?
And it is faster than PIX, which makes me think that
software based firewalls sometimes can be faster than
hareware based ones, is that right?

Thanks

Kent

Re: Cisco Documentation CD

[BIKEMAN]

Here is a workaround that has worked for all my machines.

Cheers

Rudi


Installing Cisco Documentation CD in Windows 2000

*** IMPORTANT NOTE -- PLEASE READ ***
These instructions are NOT recommended or supported
by Cisco.  They are not guaranteed to work and may
messup your computer.  The recommended solution is
to run the CD on one of the supported operating
systems or to wait until the next release of the
Documentation CD which will support the Windows
2000 operating system.  If you choose to use these
instructions, you do so at your own risk.

1.  Read the IMPORTANT NOTE above.

2.  Edit the Windows 2000 Registry Key
HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/IE4/Setup/Path
Change the value from "%programfiles%\Internet Explorer"
to "C:\Program Files\Internet Explorer" or wherever IE
is installed on your machine.

3.  Uninstall the Cisco Documentation CD

4.  Sometimes you will also have to manually delete
files or directories from the original installation
of the CD.

5.  Re-install the Cisco Documentation CD and it
should work.

IP Multicast - PIM Designated Routers...

[woody]

The literature I have (BCMSN notes) refers to the PIM Designated Router in a
broadcast environment as having the highest numerical IP address of the
neighbouring routers in the same broadcast environment (same ethernet
segment).

Does anyone know if you can over-ride the IP address on an interface by
setting a loopback address (as in OSPF DR elections)?  This would have the
effect of forcing a specific router to become the PIM DR if it didn't have
the highest LAN IP address.

Thx.

Keith :-)

Well in that case you have a definite edge.
Using the cisco acs along with cisco works
to configure appropriate network management 
you can almost catch him in the act.

I use Cisco Secure ACS, which is great because It logs all attempts to hack 
into the router whether successful or failed one's, you can apply it to 
Asyncs, VTY, and console ports, but be careful, do not lock you self out of 
the router with TACACS+.

Re: VLSM Question

[Stephen Skinner]

well lets see if he`s right .boys and girls.
first how do we calculate the sum

the ip address is 172.108.168.0
this is a class B address which would mean that in our question the last 
digit is not important.
next it has "/21" which indicates a subnet mask of 21 bits...in a standard 
ip address we have 32 bits ...
which is represented as 255.255.255.255 in DECIMAL
"/21" would indicate that the subnet mask is 
..1000.
as we are not concerned with the last digits (its a class b address which 
will use the last digit as host address) the subnet mask is actually
..1000.
first ignore the fist two sets of digits as these are not part of our 
PRESENT CALCULATION
next take the last 1000 and calculate like this
1 is for the network 000 is for the hosts
the 8 bits map to a numbering system like this
  1. 1. 1. 1. 1. 1. 1. 1
128 64 32 16 8  4  2  1

so 1000 would work out as 128+64+32+16=248

next is easy 248 -256 =8 that is the number gap beetween your subnets!!!
so not starting at 0 and not ending at 255 (reserved and broadcast)
lets count
172.108.8.0
172.108.16.0
172.108.24.0
172.108.32.0

172.108.168.0
172.108.172.0

so as one address in any subnet must be the broadcast address for that 
subnet you can see


172.108.168.1 to 172.108.172.254

that is 2046 hosts in 30 subnets

alternitively you could just download
the ip calculator form 3netgroup site and it will tell you all this


LAST SUBNETTING QUESTION PLEASEWE SHOULD HAVE HAVE GOT THIS IN 
NETWORK ESSENTIALS ON YOUR MCSE

RE: frame-relay design

[Taylor, Don]

You only need one PVC per remote in a hub & spoke environment, which in your
example would be a total of two PVCs for the whole network. Even if you were
to design a full mesh it would only take 3 PVCs to connect each site to the
other two. R1-R2-R3-R1 (I suck at ASCII art).

Think about it, if you have two PVCs on the same physical interface, going
to the same location, what have you accomplished except to include more
overhead? The second PVC can't be used for redundancy or load balancing if
it's on the same physical circuit.

Does that help?

Subject: frame-relay design


If you had 3 locations in a hub and spoke topology,
then you would want two pvcs going to each
site...(using subinterfaces), how do the numbers
change as you add remote sites...

e.g. if you add the 4th site, do you have to add a pvc
to every other site?, totalling 3 pvcs/subinterfaces ?

so would that mean if you had 100 sites it would
require n-1 (99) pvcs/dlcis/subints per location...?


i may be way off

Re: BGP question

[Howard C. Berkowitz]

>Sounds like you guys were doing IBGP...


Could be, but there are several other explanations.

Let me go into the underlying rationale.  According to RFC1930, which 
is a must-read in understanding BGP, an AS is a set of addresses and 
routers, under one or more administrations, that presents a common 
routing policy to the internet.  So, if Dan's employer had Internet 
connectivity only through the provider, the customer would logically 
be part of the provider's AS.,

Providers are usually reluctant to let customers have access to their 
iBGP.  You will see cases where the provider controls an iBGP router 
at the customer premises.

More likely, the provider assigned a private AS number to the 
customer, and either made it part of a confederation or used a rather 
undocumented Cisco feature called remove-private-as.  By doing this, 
you have all the power of eBGP policy controls, but you don't burn a 
registered AS number.

I'd like to throw out a related question to people that recently have 
taken BGP in a Cisco course, or in certification tests.  On this 
list, the term "advanced BGP" is used a good deal in relation to the 
new material. It had been my experience that the BGP in ACRC was so 
oversimplified as to have no relationship with anything one would see 
in the ISP world.  In particular, there was handwaving about 
"policies," but very little about why one has policies or how they 
are enforced -- just the urban legend that "BGP carries policies."

I'm doing a series of tutorials on BGP at certificationzone.com, the 
second of which is in the free area of the CCIE zone.  To me, they 
are at the "BGP 101 or BGP 102" level in terms of real-world Internet 
operations.

Within what people can say within NDA, are complex AS path 
expressions being considered? QoS policy setting based on AS 
path/address/community?Hierarchical route reflectors? The flavors 
of hard and soft refresh? Load-sharing policies? Cold potato routing? 
etc., etc., etc

What topics that people are seeing in BGP course material or tests on 
which you'd most like additional tutorials?  Unfortunately, I don't 
approach this topic through the eyes of a person starting with the 
technology.

Congratulations.
  Why would you re-cert CCNA if you will have your CCNP?  You should be using
that study time and brain power to study for higher certs, not regress back to

RE: collision on cut-through switch

[Daniel Cotts]

Are any current Cisco switches using cut through? The 5000s use Store and
Forward. The old Kalpana switches aka Catalyst 3000 used cut through.
Looking at an old EtherSwitch PRO16 manual (same same cat3k) it mentions
on-board buffering. "If the destination port is receiving a packet from
another EtherSwitch PRO16 port or if the output segment is busy, the
EtherSwitch PRO16 stores the packet in one of its on-board buffers. Each
EtherSwitch PRO16 buffer can hold up to 384 packets in each direction
(incoming and outgoing). This helps balance throughput when networks are
operating near peak load and more than one packet may be directed to the
same port at the same time."
Hope this helps.

re: ACL Question

[Cthulu, CCIE Candidate]

Try this:


Given:  172.88.99.0/32

You want to permit only even-numbered addresse and deny odd number
addresses of the subnet 

!  The following line will permit all even numbered addresses. 
access-list 1 permit 172.88.99.0 0.0.0.254

! The following line will deny all odd numbered addresses.
access-list 1 deny 172.88.99.1 0.0.0.254

!  Finally, assuming you want to permit everything else.
access-list 1 permit any


Here's the math (I am focusing on the 4th octet only).  The key to
matching even/odd addresses is the last bit (1) of the octet.  This is
just one way to do it.

1. Matching Even numbers.
First, break it down into binary

    = 0 (4th octet of 172.88.99.0)
 1110   = 254 (4th octet of the wildcard mask).


Remeber that 1 means don't care, 0 means must match.  In the example
above,  the last bit of the 4th octet must be 0, (that is, if the last
bit is turned on, it will not match the above, and will therefore not be
permitted).

2. Matching Odd numbers.

 0001   = 1 (4th octet of 172.88.99.1)
 1110   = 254 (4th octet of the wildcard mask).

The last bit (1) must be turned on.  Since 1 must be turned on, this
will be match all odd numbered addresses.


That is a quick answer for a MOnday morning.

HTH,

Charles

Got a good one for you all to ponder.

I am in the process of reassembling my lab. Routers have been off line for a
couple of weeks. Friday I brought two back on line to test some
configurations for someone. Discovered that I was unable to route.

Here is what I know:

Serial interfaces on both routers are up. I know this because:

1) Show CDP neighbor reveals the other router, both interfaces, both routers
2) Debug serial interface and debug serial events shows communication across
the interfaces
3) Show interface reveals the interface is up and the protocol is up, both
interfaces, both routers
4) On either router I can ping the directly connected interfaces of the
other router
5) Oh, and IPX and AppleTalk routing work just fine. I see all networks for
both protocols.

I also know that the routing protocols are set up correctly. Honest, gang.
I'm not sure how many more ways I can check an IGRP configuration with one
network in it. Let alone EIGRP and BGP ( the lab configuration I was
testing ) Besides, as I stated, I can ping the each router serial interface
from the other router.

I also found that one time, if I reloaded with an empty startup config, and
configured from the setup, that I would have routing. Admittedly I have not
done too many more experiments along this line.

Oh,  one last thing. IP routing works fine and dandy across the ethernet
interfaces. I.e if I plug both router  ethernets into the same hub, routing
is great. Even the BGP processes establish neighbor relationships with the
right information..

Well, I'm frustrated as hell. And out of ideas. I have gone so far as to
reload images into the routers. The only other thing that is a wild guess is
that two of the three routers were the recipients of new images via Cisco's
Router Software Loader. But the other one was updated the old fashioned
way - TFTP. Makes no sense to me that this would effect the ability of the
IOS to see the serial ports. I suppose strange things have happened.

I do find it rather incredible that every serial interface on every single
one of my routers has failed at exactly the same time. And failed for IP
only.

Anyone have any ideas? Is there some secret command within IOS version 12.x
that someone is keeping secret from me?

Re: extended ping commands

[woody]

You can change payloads to attempt to force certain dataconditions on the
line.  For example, a you may wish to prove the line encodingon your T1/E1
so by sending a pattern of all 0's it stresses the line encoding and timing
recovery of the link.  This is a basic data pattern test (better suited to
dedicated test equipment) to isolate problem areas.  I personally have never
played with payload contents as strictly speaking a ping is a simple
reachability test - but thats not to say you cannot use it to stress test
etc...  You may want to trigger a capture on a data analyser using a certain
datapattern that you set in the ping payload.

Try searching www.cisco.com  for more information on extended ping command
options.

  Hi all
   
  I have two 2nd hand 2501's that are giving me a 
  few headaches - when I plug the console cable into the console port I can see 
  the output but the routers don't seem to accept any input. The cable and

Re: Re:ACRC

[woody]

It took me 3 goes to pass and I never usually fail either.  I personally
think this is one HARD exam.  I failed as I didn't give the exam the respect
it deserved the first time and missed it by 4/1000 the second time (gutted).
I didn't realise you can't abbreviate the type in answers.  I creamed it on
the third go - we all live and learn...

With regard to the type in answers you can assume you are already in the
correct menu for the answer - ie: if you are asked how to set the ethernet 0
IP address you can assume that you are already at the 'router(config-if)#'
prompt.

Keep on trying - remember they retire the exam at the end of July...

Re: Interviewing advice

[woody]

Be yourself and dont try and bull the interviewer if you don't know an
answer.  Get there 10 minutes early, be smart and polite etc. etc.

I posted my CV on www.dice.com and landed a job in New York inside 21 days
(I currently work in London).  I didn't take it due to contractual
restrictions I wasn't happy with (Americans don't get many holiday days..),
but pay and other conditions seemed good for a single person wanting to move
abroad.  You can also post your resume on-line (so you can give out the URL
to possible employers and agencies) - I beleive they also have interview
tips on their web site.

'fraid not - what I normally do for this sort of stuff is copy and paste to

Re: Cisco Secure !!!!!

[David]

FYI, I found the answer I was looking for.  For Unix, you HAVE to use
some kind of database backend.  If you don't own a database product that
it support (Sybase or Oracle), you have to use Sybase SQL Anywhere, a
small Sybase compatible product that ships with CiscoSecure and supports
no more then 5000 entries.

July, 2000. Ihave two questions.  The first one revolves around 
VPN.  The other questiondeals with CISCO's Hierarchical Network Design 
concepts.(1)  Assume that I have six simple LANs - one HQ  LAN 
and 5 Branch LANs.Assume also that each LAN consists of one Server and 4 
workstations.  If Iwant to link these simple networks using VPN;  
what king of Hardware andSoftware would I have to buy. I would also like to 
compare and contrastMicrosoft's VPN (which I believe is built into Win2000) 
and CISCO's VPN.Thanks in advance guys.(2)   In this 
second scenario, I want to connect a router at each LAN siteand make use of 
CISCO'S hierarchical network design principles.  Can anyoneexplain or 
draw a simple diagram of what the network structure would looklike at the 
CORE, DISTRIBUTION, and ACCESS 
layers.Thanks,John

I recently had this problem and followed the good advice received in this
forum. Try downloading 'teraterm' from download.com. it worked for me.

Hi Zack

The console cable and port work fine (9600 baud etc - have even tried other
baud rates in case someone changed the default) - I can plug it into one of
the other routers and it works fine for hours. Nothing I type has any effect
including carraige return.

Thanks

Rudi

Re: Diff between point to point T1 and T1 with framerelay

[David]

sure.. PPP (point-to-point protocol) and Frame relay are both different
layer two protocols that run on top of the T-1 service.  PPP over T-1 is
the same PPP the is commonly used for modems when dialing up to an ISP. 
It's based on the HDLC protocol.

Frame relay has an addressing scheme separate from IP that makes it a
shared protocol that can be switched throughout a telco providers switch
network.  It uses the concept of a DLCI (Dynamic Link Channel
Identifier) and of SVCs and PVCs to implement a point-to-point or
point-to-multipoint scheme connecting many sites over a single physical
circuit.  Essentially, the provider can say ok, here's a PVC (Permanent
virtual circuit) at DLCI 16 that points to company B, and here's another
that points to Company C on dlci 17.  you set these up on your side, and
then the provider gives the other companies their own dlci numbers that
correspond to that circuit connection.  SVCs do the same thing but on an
as-needed basis.  many providers don't support these.  frame relay also
provides LMI (local mgmt. interface) to list DLCI numbers and assure
connectivity (among other things) to a FRAD (frame relay access device).

it's important point to note that because of frame relay's features and
the fact that it is switched (PPP is mapped directly from point A to
point B by the provider), mean that overhead is incurred and a portion
of the total circuit bandwidth will be used by the protocol.  So, a T-1
won't be able to run at a full T-1 speed over frame relay, and the
network won't provide you assurance of that unless you give them lots of
money.  This gets into congestion control (FECN and BECN) and the
concept of CIR.

Many of these terms (HDLC, frame relay, PPP, T-1, etc.) are fairly well
definied with links to further explanations at http://www.whatis.com.

i love network acronym speak.  it makes me feel like a doctor.

hope this helps,
david

Re: Fast Etherchannel on 7513

[Nigel Taylor]

Also take note that there are only certain versions of the IOS that supports
the standard dot1q(802.1q) at our shop we ran into a problem after upgrading
our RSP's to 12.0(10) which cisco sent us only to find out that it's only
isl capable. Now we've got to go back to 12.0(3)T in order to support dot1q.

Re: Can I implement HSRP on C2500 series router?

[Dir]

In fact you can use HSRP on the 2500 series. Thing is that they do not
support virtual MAC addresses (as you said), this is only supported on the
7000 series (or higher). This means that one of the routers (depending on
the priority) will respond to the ARP request of the clients with its own
MAC address. If this router fails, then the other one will take over, ie
respond with its own MAC address to the ARP request to the (virtual) IP
address of the HSRP group.
You can figure out the problem: as long as the MAC address of the first
router is in the ARP cache of the client, nothing will work if the router
fails, even if the second one takes over. It takes a new arp request to the
'new' MAC address of the HSRP group for things to start working again.
Hope this clears things out a bit?

here is the result:

^
% Invalid input detected at '^' marker.

CR357136-C(config)#

... depending on how good this pasted the caret (^) is under the a in
area.

not good.
