But I thought that I'd seen or heard of using split horizon with
OSPF...maybe I'm thinking of Frame Relay...long day I guess...

Re: Function of IP HELPER ADDRESS & IP DIRECTED BROADCAST ?

[Larry Lamb]

ip helper-address is used to relay BOOTP/DHCP and other services from the
attached network to a known point on your network (the helper address).  ip
directed-broadcasts allows you to forward broadcast pings, etc.  This should
typically be turned off unless you really need to use it.

See
http://www.cisco.com/univercd/cc/td/doc/product/software/ssr83/rpc_r/48383.h
tm for more on both subjects.

Cisco have one on their web-site.  I take it you're after the R&S exam, be

RE: what is the average age of people in this stuff?

[patel]

I agree with that point. I work in a company and i always find them saying i
am not experienced enough. I started of at 17.5 years and i am 22 now. I
have my cne(4.11 and 5) MCSE(not that it's valid that much), Master
CNE,CCNA,CCDA,CCNP and CCIE written is almost complete. I have designed and
implemented networks consisting with upto 20 GSR and 10 6509, and done a lot
on the troubleshooting area as a testing engineer. I have used equipment
from smartbits to generate specific protocols traffic and see the network
effects and much much more. But my manager says that he knows how capable i
am and only gives me basic paper work like get this signed and finish the
document etc. If i provide any solution they say i do not understand whats
going on currently. And can you guess which company this is  look at my
email address and that should be enough.

Any way i am moving to somewhere where they understand that i am ok and will
not be doing pure paper work.

I find myself in much of the same situation Dale is in.  At 20, I am busting
with energy most of the time. I know how to fix the problems and I have the
desire to, but I often get the "you're not old enough and experienced
enough" excuse from people who haven't seen my work.  A lot of people assume
that experience and ability comes with age. I agree with that point to a
degree.  However, I know a lot of teenagers who are brilliant and a lot of
people in their 40s who don't have sense enough to get out of the rain. :-)

Microsoft and Cisco (was Re: juniper and cisco)

[Bradley J. Wilson]

Someone wrote:

> I get chills when I think how similar cisco is to Microsoft...

Nah, I disagree - they're worlds apart.  First of all, neither one is a
monopoly - the DoJ has their head up their ass.  Secondly, Cisco's response
to bugs is "Whoops, there's a bug in our software - here's the patch,"
whereas Microsoft's response is, "Bug?  I'm sorry, you must be mistaken -
it's a *feature*, which you're simply implementing incorrectly."

Sure, they both eat up other companies.  But while Microsoft eats other
companies and then suppresses their products, Cisco integrates them and
allows them to flourish on their own.

Cisco/3Com compatibility

[Shaun Wakelen]

Hi all

Does anybody have any experience of compatibility issues between a Cisco
switch and a 3Com switch? We have a 3548 connected to a 3Com SuperStack II
Desktop Switch. The link is manually set up as 100MB full duplex, and a show
interface on the 3548 shows a large number of CRC errors, but no collisions.
Reading various docs, I believe that this would normally be caused by
excessive noise.

The 3Com was set up for a forwarding state of Fast Forward, and after 3
hours of monitoring yesterday I changed it to Store and Forward. Before it
was changed there were 700 CRC errors within the 3 hours, and after I
changed it, there were only 30 errors in the next 3 hours.

There are clients connected to the 3Com switch that are having the odd
connection problem, but if the are moved directly onto the 3548, they no
longer get problems. I thought perhaps the errors may be due to excessive
traffic, but if you look at the 2 interface stats below, one port has more
traffic than the other, but less CRC errors:

Your observation about the wording is fascinating.  I may be involved 
in setting up a commercial remote lab service, and, in any case, 
supervise scenario development for CertificationZone.  The problem 
you are describing also applies to practice exam development as well 
as lab practice.

It is my impression that the CCIE lab, at least, really does focus on 
specific features rather than best solution -- I'm thinking of 
comments I've heard such as static routes being forbidden in many 
scenarios.  Such a focus does make sense, in a way, for Cisco -- it's 
easier to train proctors to evaluate more constrained solutions.

But my own feeling is that scenarios that make you think about 
solutions are better from an educational standpoint -- definitely for 
real-world preparation, and secondarily for exam preparation.

What's the feeling of people on this list?  Do you prefer scenarios 
that mimic the lab as closely as possible (without violating NDA), 
scenarios that exercise problem analysis, or a mixture of the two 
with clear identification of the scenario designer's intention?  Am I 
representing the lab reality correctly?

[Andrew Larkins]

Sorry for being vague before

I tested this in the lab and it works great for password recovery. Problem
is however that the client tried this and now the display is garbled. My
test was on the same router - no problems. 
Is it possible for the hardware to be damaged???

Re: what is the average age of people in this stuff?

[Cthulu]

Some shoe polish to age up and down the scale may help.

If you are perceived as too young, apply some white shoe polish around your
temples, and then complain about the youth of today, and how, in your day,
you were luck to have 16 bits to play with.


If you are perceived as too old, darken your hair with the appropriate color
of shoe polish, and complain about the stodginess of the old people, and how
they complain about having had to work with 16 bits in the old days.  Say
"man" and "cool".


HTH,

Charles

Re: cisco like microsoft? (was Re: Juniper

[ramius]

I don't get where the "bitter" in the competition comes from. That's
business. The major difference between Cisco and Microsoft is what is done
with the aqusitions afterwards. Microsoft uses the "you will be assimilated"
strategy, changing the ways that the bought companies work to conform to
Microsoft and even changing the way they do "whatever is is they're doing."
Cisco on the other hand, lets the aquistions keep doing what they know how
to do--that's what made them successful in the first place. There is
definitely a more hands-off approach.

Re: Question on Cisco Voice Capabilities

[Nuurul Basar]

Hai,

I have a question regarding Cisco E & M port and it RJ
45 connection.

Can any one tell me how do we know which is 1--8?.
According to the Cisco Press Intergrated Voice the
female going to cisco router will be on my left thus
the collor coding will start with white orange as 1.

Once we plug in the RJ 45 to the voice port is there
any thing that can be done to check phsy?.  I was
stuck for 2 day when my vendor did not detect any
problem with the port until we make a new cabling and
the other E&M card was working fine.

Thanks

Re: 2600 router - 12.0 IOS wanted

[Kevin Wigle]

Why???

I'm not sure why a person would need to be a Silver Partner.  Anyone who
buys the "smallest" smartnet can download just about anything.

There are also Resellers/Premier Partners who sell smartnet who register the
smartnet for the customer (I just attended a Cisco seminar that advised
resellers to do this) so they have access when those packages are registered
and are in the loop for customer's problems. (and when they need to be
renewed)

I'm not aware of the "special" rights a Silver Partner has do they have
unlimited access to IOS?  Or just to the versions that they have sold to
their customers (or own smartnet on themselves)?

Re: how to find snmp traffic for an interface

[Tom Pruneau]

Create an access list on that interface that permits the specifed traffic.
Then periodically check the access list and see how many mathces it has had.

Also don't forget to put a permit ip any any at the end of your access list
to let through all the other taffic which wasn't explicitly permited

RE: Config register 0x142 - what speed does this change the port to??

[martijn michiel]

Andrew, (little late..) dunno, cisco states the standard:

http://www.cisco.com/univercd/cc/td/doc/product/access/acs_fix/cis2500/2509/acsvrug/maint.htm#22754

>>>.
Step 2 Configure the terminal to operate at 9600 baud, 8 data bits, no 
parity, 2 stop bits.

Step 3 Enter the command show version to display the existing configuration 
register value.

Step 4 If Break is disabled, power cycle the access server. (Turn the access 
server off, wait five seconds, and then turn it on again.) If Break is 
enabled on the access server, send a Break and then proceed to Step 6.

Step 5 Within 60 seconds of turning on the access server, press the Break 
key. This action causes the terminal to display the bootstrap program prompt 
(>).

Step 6 To reset the configuration register to boot from the boot ROMs and 
ignore NVRAM, enter o/r at the bootstrap prompt as follows:

>o/r 0x042


Step 7 Initialize the access server by entering the command initialize as 
follows:

>i


The access server will power cycle; the configuration register will be set 
to 0x142; and the access server will boot the boot ROM system image and 
prompt you with the system configuration dialog as follows:

>>
Also:
>>
Bits 11 and 12 in the configuration register determine the baud rate of the 
console terminal.
Table B-6 shows the bit settings for the four available baud rates. (The 
factory-set default baud rate is 9600.)


Table  B-6: System Console Terminal Baud Rate Settings Baud  Bit 12  Bit 11

RE: Vunerabilities to be announced in IOS

Subject: Vunerabilities to be announced in IOS


Slightly OT.

Cisco is announcing a number of security holes in
certain versions of the IOS, likely tomorrow. A number
of them are starting to get exposure in the security
press already, and ISPs have been briefed and should
have patches and other temporary fixes in place
already. Enterprise customers (some larger ones) were
briefed today and have already taken steps to thwart
attacks.

The two biggest threats in my mind are:

- A default SNMP RW string of ILMI.
- A guessable TCP sequence number process - this could
be used to hack BGP and other router processes.

There are a number of others. Most of us will be same
because the attacks need access - for example, you
deny SNMP from the untrusted networks, right? Thus,
ILMI is just another guess at the password/string. BGP
should only accept packets from the neighbor, so
again, a non-issue hopefully.

The biggest reason for posting this here is for those
studying security - the next few days should be very
interesting to watch.

BTW, I love the monikers on this list.

Anyhow, my impression comes from sales in our discussion of relative

was deluged with FUD. What I was looking for was why an end-to-end cisco

YMMV, of course.

If you're thinking of X-Modem, it isn't supported on the 2500 series 
BootROMS.

The only thing I can think of is using PPP over the aux port, connected to 
something running a tftp server, and PPP.  You'll need a static route, and 
I'm nbot sure whether this config will be read by the bootrom for it to 
work.

I had this problems with a 3640 when they were first released, we ended up 
copying the flash on another router, and plug the flash card into the 
router.  Messy, but it works, and you need two routers to do it.

What about exchanging the 2 flash chips? first save with a router that

Some shoe polish to age up and down the scale may help.

If you are perceived as too young, apply some white shoe polish around your

you were luck to have 16 bits to play with.


If you are perceived as too old, darken your hair with the appropriate color

RE: NM-1E

[Christopher M. Heffner]

If you only the 2610 then you might want to think about selling or
swapping the 2610 for a 2611 instead.  It might be cheaper in the long
run.

I found out the hard way last week that any Lan module with the wic
slots are NOT support by Cisco in the 2600 family.  I was trying to add
more serial interfaces to my 2621 last week to simulate the ANEW 2 labs.

Cisco says only the NM-1E or NM-4E is support in slot 1 for LAN modules.


My choices were to use either the NM-2W module for my serial interfaces
or to upgrade from the WIC-1T cards to the WIC-2T or WIC-2AS cards or
use my 3640 instead.

Good Luck,

Another option would be to enable cache-flow on that interface, turn on
flow-export and use cflowd to display utilization by protocol.

For cflowd information, see http://www.caida.org/tools/measurement/cflowd

(10 days to my lab, and counting!)

Re: Anyone ?? Cisco has no answer after week..LATENCY IN PINGING ISDN SITES

[kent . hundley]

Inamul,

Are you absolutely sure that your not dropping the line and making 
separate calls?  Try "debug dialer", "debug isdn q931" and "debug 
isdn q921" to see if you see anything unusual happening during the 
ping process.

Regards,
Kent

RE: back-to-back cable AGS+ and 2523

[Daniel Cotts]

Do a "show controllers s 4" on the 2523 to verify that the router sees a DCE
cable.

I have no experience with the AGS+. However, some serial ports are sync
while others are async. Which ones do you have?

RE: Bootcamp lab#6

[Frank Wells]

I tried that at. All I got from IOS was something to the effect: You cannot 
use a local interface for this operation'

I guess what your trying to say is use a loopback on a different router from 
the one where you want the SAP's advertised form.  This doesn't seem to make 
a whole lot of sense however.  You might as well just use an interface off 
another IPX router in your network to do this.  To use a loopback interface 
from another router it must have the IPX network advertised from it so the 
SAP-originating server can learn it.

RE: back-to-back cable AGS+ and 2523

[Maness, Drew]

On the AGS, unlike the 2500's and above, the DTE, DCE setting is actually a
jumper on the serial card.  You will have to go in and remove the card and
set/verify the jumpers.

This link will provide you the correct jumper settings.  More than likely it
is set for DCE, the default

http://www.cisco.com/univercd/cc/td/doc/product/core/cisagspl/agscfig/34084.
htm#xtocid2857013

Let me know if you have any other questions.  I have two AGS running in my
lab.  One for a frame-switch.  The other is pretending to be a 2502 until I
can purchase one.

Regards,

Drew

RE: FR + Poison Reverse...

OSPF does use Split horizon.  I don't think OSPF uses PR because PR sets the
route to infinity and I'm not sure what an ' infinity' cost would mean in
OSPF.

IPSec, IKE, VPN study resources?

[Brian Lodwick]

Group,
   Can anyone out there help me out. I am trying to find resources for 
study. I want to get learn as much as possible about IPSec and VPN 
technology. I would like to see if anyone knows of some good resources to 
learn more about this kind of stuff  -IPSec tunnel and transport modes, 
Security Associations, ISAKMP\OAKLEY process, The Diffie-Hellman algorithm, 
and ...

What I would really like to find is a book that gets right into the guts of 
it and goes through it inside and out. I'd also like to learn the  history, 
and where the forefront is trying to push this technology.
If anyone knows of any resources they have found helpfull I would really be 
gratefull for your response.
Thanks in advance guys-

If you only the 2610 then you might want to think about selling or
swapping the 2610 for a 2611 instead.  It might be cheaper in the long
run.

I found out the hard way last week that any Lan module with the wic
slots are NOT support by Cisco in the 2600 family.  I was trying to add
more serial interfaces to my 2621 last week to simulate the ANEW 2 labs.

Cisco says only the NM-1E or NM-4E is support in slot 1 for LAN modules.


My choices were to use either the NM-2W module for my serial interfaces
or to upgrade from the WIC-1T cards to the WIC-2T or WIC-2AS cards or
use my 3640 instead.

Good Luck,

The only Async ports on an AGS+ are the Console and Aux. (Same for MGS, CGS 
has 16-port async cards(IIRC))

I think you're getting confused between low-speed (S) and high speed (T) 
ports.

RE: NM-1E

[Christopher M. Heffner]

Beware ... the wic-1e is currently only support on the Cisco 1700
product line.  Cisco list the Wic-1e as unsupport on the 1600, 2600 and
3600 platforms currently.  Maybe in the future.

Cisco now offers a WIC-1E for the 1600, 1700, 2600, and 3600.  It
retails
for $238 USD on cdw.com  It is only 10mb

Hope that helps

If you only the 2610 then you might want to think about selling or
swapping the 2610 for a 2611 instead.  It might be cheaper in the long
run.

I found out the hard way last week that any Lan module with the wic
slots are NOT support by Cisco in the 2600 family.  I was trying to add
more serial interfaces to my 2621 last week to simulate the ANEW 2 labs.

Cisco says only the NM-1E or NM-4E is support in slot 1 for LAN modules.


My choices were to use either the NM-2W module for my serial interfaces
or to upgrade from the WIC-1T cards to the WIC-2T or WIC-2AS cards or
use my 3640 instead.

Good Luck,

There's a great book by William Stallings called  
"Network Security Essentials: Applications and Standards"

Very good coverage of everything you mention... but it 
has been known to cause headache's if read too fast.  =)

RE: IPSec, IKE, VPN study resources?

[Maness, Drew]

For a starting out point I would recommend Enhanced IP Services for Cisco
Networks by Donald Lee.  He does a great job explaining how cisco handles
IPSEC and IKE.

Next I would recommend Cryptography and Network Security - Principles and
Practice by William Stallings.  Probably the best free book I received from
cisco.  (Besides Small Business Networking for Dummies--I keep it smack dab
in the middle of all my cisco/networking books.  You should see peoples
faces when they come across it ;)

After that you should probably head to the RFC's: (God I'm starting to sound
like Howard :)
RFC2104 Hashing
RFC2402 AH
RFC2406 IPSec ESP
RCF2405
RFC2408 ISAKMP
and a bunch more

Have fun

Re: Good book on RIF?

[Andrew Shappell]

The Lou Rossi's paper is the best source of RIF information that I have found 
to date.  It is an absolute must read.  It easy to understand and well written.  It 
has cleared up and removed all the mental blocks that RIF was presenting to me with. 
Thanks again for the excellent source of information.

I picked it up but have not had a chance to read it yet. My list of books to

RE: FR + Poison Reverse...

[Brian Lodwick]

OSPF uses split-horizon? I don't think this is correct. I hate to be quick 
to reply but there is no reason for OSPF to use split horizon. OSPF sends 
updates to all adjacent neighbors, and in NBMA , and Broadcast network types 
the DR forwards the updates on.
Split-horizon is used to keep routing loops from happening for a 
Distance-vector protocol not a link state protocol.
There is an issue split-horizon presents when using a distance-vector 
protocol in a frame-relay hub spoke topology. As you can imagine (if you 
know how a distance-vector protocol diseminates updates) the hub will need 
to send the update back out of the interface it received it on so that the 
other spokes will receive the update. This will not be allowed to happen if 
split-horizon is enabled. The spokes will not be an issue.

By default:
Physical interface frame-relay setup split-horizon will be disabled.
Subinterface frame-relay setup split-horizon will be enabled.

Also keep in mind you cannot disable split-horizon on IPX RIP.

Summation when you have a hub spoke frame-relay topology and you are using a 
distance-vector routing protocol you need to disable split-horizon on the 
hub. (which does leave you secceptible to the issue split-horizon was 
designed to fix)

Or use a link-state protocol.

Or you could setup point-to-point subinterfaces on the hub for each spoke.

RE: Anyone ?? Cisco has no answer after week..LATENCY IN PINGING ISDN SITES

[Desai, Inamul]

Hi Kent:
I have SNMP traps turned on router which is monitored
by HP OpenView. I also chk sh log quite few times a day and make
sure the none of site is flapping. Nothing gets reported in
OV so I do not think it's dropping lines, I do notice when ever 
it drops lines but I do not think line is issue here. This 
ping sort of cycles from site to site so x site would return big   than
y , than Z and so on.
Thanks for response..

Inamul,

Are you absolutely sure that your not dropping the line and making 
separate calls?  Try "debug dialer", "debug isdn q931" and "debug 
isdn q921" to see if you see anything unusual happening during the 
ping process.

RE: FR + Poison Reverse...

[Brian Lodwick]

After verifying my thoughts with referrences I am now confident OSPF does 
not in any way use split-horizon. I was a little leary to be absolutely sure 
right away, since there are often nuances that exist.

Split-horizon, Poison Reverse, and Hold down timers were created to overcome 
loops caused by the way Distance-vector protocols converge.

RE: FR + Poison Reverse...

[Leigh Anne Chisholm]

If you don't want to read all of my quotes, look for the portion contained therein 
enclosed by double asterisks (**).

>From Cisco's site:

"Normally, routers that are connected to broadcast-type IP networks and that use 
distance-vector routing protocols employ the split
horizon mechanism to reduce the possibility of routing loops. Split horizon blocks 
information about routes from being advertised by
a router out any interface from which that information originated. This behavior 
usually optimizes communications among multiple
routers, particularly when links are broken. However, with nonbroadcast networks, such 
as Frame Relay and SMDS, situations can arise
for which this behavior is less than ideal. For these situations, you might want to 
disable split horizon. **This applies to IGRP
and RIP.**"  This excerpt can be found at:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios11/cbook/ciproute.htm#xtocid16743169

A few weeks ago, this same discussion was brought up.  Someone posted the following 
link outlining "Hub And Spoke Frame Relay Sample
Configuration - Dynamic (OSPF) IP Routing".  Here's an excerpt from the link:

"In general, it is good practice to use subinterfaces for partially-meshed frame relay 
networks. A frame relay network designed with
subinterfaces scales much easier to future expansion. Referring to the example, 
subinterfaces allow routing updates to exchange
between Boston and Chicago through Atlanta. **Without subinterfaces, Boston is unable 
to receive routing updates from Chicago and
vice versa creating a condition known as split-horizon.**"  This excerpt can be found 
at:

http://www.cisco.com/warp/public/779/smbiz/service/configs/framerelay/fr_ip_ospf.htm

Now this is in contrast to what I know of OSPF and in contrast to the first quote I've 
included.  Quite frankly, I would think that
the problems encountered in the Frame Relay example have more to do with the 
non-broadcast nature of Frame Relay than split-horizon
so I think whomever wrote this may have misunderstood why subinterfaces enable routing 
updates--and I think perhaps this is why
there's so much confusion over whether or not split-horizon plays any role in OSPF.

Brian L:

I think you've got it backwards as to when split-horizon operates on an interface.  By 
default, all Cisco serial interfaces are
multipoint unless specifically configured to be point-to-point.  With multipoint, 
you'd want split-horizon enabled if you were using
a broadcasting routing protocol.  Here's two excerpts from Cisco's site:

--Excerpt 1--

"Note: For TCP/IP, Cisco routers can disable split-horizon limitations on all frame 
relay interfaces and multipoint subinterfaces
and do this by default. However, split-horizon cannot be disabled for other protocols 
like IPX and AppleTalk. These other protocols
must use subinterfaces if dynamic routing is desired."

--Excerpt 2--

"Cisco serial interfaces are multipoint interfaces by default unless specified as a 
point-to-point subinterface. Though less common
than point-to-point subinterfaces, it is possible to divide the interface into 
separate virtual multipoint subinterfaces."

"Multipoint interfaces/subinterfaces are still subject to the split-horizon 
limitations as discussed above. All nodes attached to a
multipoint subinterface belong to the same network number. Typically, multipoint 
subinterfaces are used in conjunction with
point-to-point interfaces in cases where an existing multipoint frame relay cloud is 
migrating to a subinterfaced point-to-point
network design. A multipoint subinterface is used to keep remote sites on a single 
network number while slowly migrating remote
sites to their own point-to-point subinterface network."

"Figure 4 shows serial 0.1 as a multipoint subinterface connecting to three different 
locations. All devices on the multipoint
subinterface belong to the same network number (100). Site E has migrated off of the 
multipoint network to its own point-to-point
subinterface network (200). Eventually, all remote sites can be moved to their own 
point-to-point subinterface networks and the
multipoint subinterface will not be necessary."

Both of these excerpts can be found at:

Brian's reply:
You have just cut from a cisco document that proves I am accurate. This says 
all interfaces are by default multipoint unless specifically configured 
point-to-point. This is talking about physical interface configuration not 
multipoint subinterface configuration, and you have just proved I am correct 
that Physical interfaces configured for frame-relay by default disable 
split-horizon. Also if you want a distance-vector protocol to work correctly 
on a Frame-relay hub & spoke model split-horizon must be disabled on the 
hub(unless the hub is configured for point-to-point to each spoke)

RE: FR + Poison Reverse...

[Brian Lodwick]

OK I finally read what you were talking about.
It says it creates a condition known as split-horizon. I believe the key 
word here is "Condition". This is not the split-horizon that is used to 
prevent loops in a Distance-vector algorithm. I have added comments below.

Let's disect these paragraphs:
This sample configuration routes TCP/IP over a partially-meshed frame relay 
network using point-to-point subinterfaces. IP routes are dynamically 
resolved using Open Shortest Path First (OSPF) as the routing protocol. 
Special care is needed when configuring OSPF over partially-meshed frame 
relay. ~~1~~ OSPF requires direct connections to each neighbor in order to 
elect a Designated Router (DR) and form adjacencies with neighboring OSPF 
routers. However, the physical topology of a partially-meshed frame relay 
network does not provide the direct access that OSPF requires.

The solution to the adjacency problem is to use subinterfaces. Subinterfaces 
logically divide a single, physical interface into separate, virtual 
point-to-point interfaces. A single frame relay interface connecting to 
multiple destinations can now be treated as a collection of point-to-point 
network segments. The point-to-point connections allow routers to form OSPF 
adjacencies without DR election. Although each subinterface segment requires 
a unique IP subnet, unnumbered IP segments can be used to alleviate the 
burden of designing the additional IP subnets.

In general, it is good practice to use subinterfaces for partially-meshed 
frame relay networks. A frame relay network designed with subinterfaces 
scales much easier to future expansion. Referring to the example, 
subinterfaces allow routing updates to exchange between Boston and Chicago 
through Atlanta. ~~2~~ Without subinterfaces, Boston is unable to receive 
routing updates from Chicago and vice versa creating a condition known as 
split-horizon.

1- this is what I feel they are referring to whe they say "a condition known 
as split-horizon." If subinterfaces aren't used and physical interfaces are 
on a partially mashed network OSPF does not provide the direct access that 
OSPF requires.

2- This says "without subinterfaces" this condition occurs.

I feel you have taken this article out of context and have made an 
assumption that this is saying that OSPF uses split-horizon which is an 
added feature to Distance-vector protocol. I believe this "condition" they 
call split-horizon has similar attributes to the distance-vector feature. 
The big difference is that this is a condition, not a feature. In this 
example split-horizon is not being used by OSPF to suppress updates from 
going back out of the interface. This is a condition encountered when you 
use physical interface configuration in a partially-meshed environment where 
OSPF will not be able to operate properly. Boston will not be able to 
receive updates from Chicago if physical interfaces are used because in this 
environment direct access is not provided for DR/adjacencies to occur.

I would like to see scenarios that exercise problem analysis. The way I see 
it, you should learn the concept before you start thinking about the 
specifics. Problem analysis exercises would help people build a strong basic 
understanding of what needs to be done in certain situations. With this 
understanding, it would easier to cope with the CCIE lab.

Re: juniper and cisco

[W. Alan Robertson]

I have resisted the temptation to get involved in this, but since it's already
being discussed some, I've got a question:

"Net Bum" <[EMAIL PROTECTED]> wrote:

This is not the first time I've heard this; major ISPs utilizing Juniper in
parts of their core, but always using Cisco at the edge.

About 6 months ago, I was down at one of Cisco's offices in Florida (Ft.
Lauderdale), for a 2 day BGP seminar.  I caught the guy who was giving the
seminar out in the hall afterward, and we were talking about a multitude of
topics, and Juniper came up.  He had mostly good things to say about them,
particularly about their speed (He was a relatively new employee at Cisco...  He
might not have drank the Kool-Aid yet).

One of the things he did criticize, however, was some kind of problem Juniper
had with their BGP4 implementation, and he specifically mentioned that Juniper

Is anyone on the list familiar with a problem with Juniper's BGP implementation

DS3 -- no channelized

[Donohue, Steve]

Good Afternoon Group,

I was wondering if someone could give me a hand.  

I am trying to a configure T3 controller on a 7507 using the no channelized
command.  The router will not accept it.  I am running IOS 12.0(5)T1.  I
want to open the pipe to full bandwidth without configuring the T1
interfaces.

Any help/links you have to offer I would appreciate.

Thanks.

Fw: juniper and cisco

[W. Alan Robertson]

Hate to follow up on my own message, but here goes:

After sending, I ran to google to see if I could find out what this problem was
about.

It seems that JUNOS had a dampening bug at one point where it would doubly
penalize a flap, once at withdraw time, and again at re-advertise time.

The link I turned up that describes the issues is at:
http://www.cctec.com/maillists/nanog/current/msg00140.html

This was from back in December, so I would imagine it's been corrected by now.

NAT/PAT Question

[Warrick FitzGerald]

Hi All,

I am trying to configure NAT/PAT where all I am trying to do is change to
Destination Port (DP) of traffic ie. all traffic with a DP of 443 and a
specific destination IP Address (DA) of xxx.xxx.xxx.xxx should be NAT'ed to
xxx.xxx.xxx.xxx with a DP of 444.

Why does this not work ?

ip nat inside source static tcp 65.143.50.10 443 65.143.50.10 444

RE: FR + Poison Reverse...

[Leigh Anne Chisholm]

Whoops!  When I posted Excerpt 1, I missed the part in the first sentence that
seems to imply that frame-relay interfaces and multipoint interfaces disable
split-horizon BY DEFAULT (when using TCP/IP).

When I took ICRC so many years ago, I remember discussing split-horizon but
don't recall any explicit mention that split-horizon is disabled by default
for the IP routing protocols (RIP and IGRP).  I remember discussing this issue
as well in CIT but I don't think the exception to the rule was noted
either--but because I wasn't aware of it, it may have been something that went
in one ear and out the other.

It's interesting to note that in the current ICND curriculum, I know the
section that talks about configuring subinterfaces indicates that "multipoint
subinterfaces act as NBMA network so they do not resolve the split horizon
issue".  I don't have the entire official ICND curriculum available, but I
don't notice anything specifically mentioning the exception.

So, in summary - we're both right with respect to multipoint interfaces:

With multipoint (or physical) interfaces: split horizon is ENABLED by default
unless you are routing IP across the link.  Then it is DISABLED.  If you're
routing using RIP, IGRP, or EIGRP to route IP, it's DISABLED.  If you're
routing IPX using RIP, EIGRP, NLSP, it's ENABLED.  It's also enabled if
routing AppleTalk.

With point-to-point subinterfaces, split horizon is ENABLED but isn't much of
an issue since it's a point-to-point link.

Well, I have not been to one yet but I want to go!  My husband went last
year to the one in Las Vegas and he had a great time.  Aside from the fact
that it was in Las Vegas (which would be fun enough for me!), they have a
ton of classes for you to take.  I think they are mainly the lecture type
(no labs) and lots of parties and fun stuff to do.  I am going to try to
make the one in Los Angeles this year.  I just wish they were holding it in
Las Vegas again.

I am sure someone on the list can give you first hand experiences of the

That sounds fishyWhy would Juniper Engineers say that their products

You a little behind here.  That was the Dell'Oro Group's estimates for third

Enterprise).

Tons?  Which ISPs are you refering to?  I tend to follow Howard B.'s belief 
that most ISPs (in the core) use more than one vendor.  I talked to an 
install engineer at uunet two weeks ago when I brought up a T1 for a remote 
office.  I had a Cisco 2600 series on my side and I asked him what he had on 
his side.  He said (as if I wouldn't know :-), "A big router, it's a Cisco 
12000 series."  Then I asked him, "Do you use any Juniper stuff?"  He said, 
"Yes, we use them in our core.  They are behind the 12000's."

>But I have to admit, Juniper does make some good stuff too (Lots of 
>ex-Cisco employees migrated over to Juniper to work there).
The most important asset to a technology company is their intellectual 
assets.  If their top employees (guys who wrote the BGP, OSPF, MPLS, ISIS, 
etc. code) leave, they won't be able to replace them.

>But I'm partial to Cisco and their equipment

I can understand that.  Many people on this list have vested interest in 
Cisco (both hardware and intellectual).  It would be terrible if our Cisco 
skills were no longer marketablebut I don't think this will ever happen. 
  Cisco still dominates the Enterprise.  Knowing how to configure Cisco 
products will land you a nice paying job.  Knowing Juniper products will 
land you a nicer paying job.  Knowing both Cisco and Juniper will land you 
an even nicer paying job :-)

I may be way off here, but there are two types of PA's, channelized and
clear-channel. If you have channelized, then I don't think you can make it
clear channel, ie, get 45 meg out of it (assuming thats what you are

RE: FR + Poison Reverse...

[Brian Lodwick]

Leigh Anne Chisholm,
Actually by default on IP interfaces:
Split-horizon is disabled on Frame-relay physical interfaces
Split-horizon is enabled on Frame-relay point-to-point and multipoint 
subinterfaces
(but who cares it's configurable)

There is a difference between a multipoint physical interface and a 
multipoint subinterface. Althought there aren't too many differences (static 
mapping and dynamic mapping allowed on both) there are subtle differences. 
My brother and I went over this yesterday and wondered what the differences 
are. What we came down to was that the big difference is simple 
-subinterfaces function is to provide a means to logically separate a 
physical interface. The subtle differences like the default split-horizon 
setting and default OSPF network type aren't the big differences. You can 
build a fully scaleable hub spoke frame model using a physical multipoint 
interface on the hub and point-to-point subinterfaces on the spokes. The 
advantage of using the Multipoint subinterface on the hub? You would only 
need 1 physical interface for 2 hub spoke frame models. I am interested in 
learning more about other things you can do with the hub as a multipoint

Perhaps as ISPs expand, they migrate their existing boxes to the edge. Just 
as their old 7500's moved to the edge when the 12000's came out.  Now the 
12000's move out to the edge when the Juniper's came out.  Just a 
thought...not sure that they did this.  It would seem very wasteful to pitch 
a 12000...why not reuse it...

Re: Fatkid - Adv BGP Lab 325

[Dan]

Sorry for the delayed response.  I don't remember all the details of the
lab, but I can tell you that the purpose of neighbor 
send-community"
string is to instruct the router to pass along any community information
that may be included in each prefix.  If you are flagging any routing info
with community information, you must specify to include this info when
exchanging updates with neighbors, either by "neighbor x.x.x.x send
community" or by assigning that attribute (and any other common
info/attributes) to a peer-group, then putting each BGP peer in that peer
group.

RE: what is the average age of people in this stuff?

[Fred Danson]

Andy,
I'm in a situation that is similar to Dale's, and I disagree with some of 
your comments. I'm 19 years old and currently working as a Jr. Network 
Engineer. I have A+, Net+, CCNA, CCDA, and 3/4 tests for the CCNP. I also 
plan to take the CCIE written in 13 days. :)

First of all, what makes you think he is impatient and immature? Have you 
actually met Dale? What evidence leads you to believe that he is? Mabye the 
people who are calling him impatient and immature are the same people who 
are fearing that he's gonna take their jobs.

>1. Be humble.

I don't think that humility is always a virtue. Of course, I'm not saying 
that it is good to be arrogant, but being aggressive usually pays off. If 
you're proactive with taking on new responsibility and if you have 
confidence in your capabilities, then your superiors will notice you before 
the humble guy.

>2. Remember everyone has *something*.

I don't really agree here. You wont find that everyone has something to 
offer. There's a guy at my work who doesn't know a thing about his job, but 
knows how to fool other people into thinking he does. Whenever we have to 
troubleshoot something, all he does is slow us down. The key here is to get 
the job done while making him/her feel like he/she contributed.

Again, why are you making assumptions about Dale? What makes you think he's 
condescending? No offense, but I find your writing to be very condescending. 
You write as if you're superior to him. Do you believe that your age makes 
you superior?

>4. Keep your age a secret. Its none of anyone else's business  and will
>only hold you back.

I dont hold my age back at all. In fact, I think my co-workers (the next 
youngest guy here is around twice my age) easily accepted me into our work 
environment because I was completely open and never defensive. People will 
be suspicious of you when you try to hide things.

I agree with this, it never helps to be negative.

>6. Consider how you view a 14 year-old. You essentially know their every

I disagree, not everyone is the same. do you know exactly what I am thinking 
right now? I think not.

>Your only 5 years older then them. Think about how

I totally disagree. Age does not completely define a person's behavior. 
Never judge a book by its cover. People will resent you if you make 
assumptions about them.

You can't get into a network engineer position by knowing nothing. If you 
convince yourself that you know nothing, then you will have trouble being 
decisive. You would constantly doubt your actions. You definitely need to 
have confidence in your bilities, but don't go too far by letting it get to 
your head.

Overall, I think that it is important to think critically about any 
situation. Many young people in the computer industry are excellent network 
troubleshooters, but horrible "people troubleshooters". If a person resents 
you, there has to be a reason for it (just like with any computer problem). 
Theres a solution to every problem, and you'll probably find yourself 
"troubleshooting" people problems more often than computer problems. You 
have to find out why they resent you, and try to fix it. Some people just 
dont trust other people when they first meet them, so ,in many cases, you 
have to take the initiave in establishing rapport.

I may be way off here, but there are two types of PA's, channelized and
clear-channel. If you have channelized, then I don't think you can make it
clear channel, ie, get 45 meg out of it (assuming thats what you are
trying to do).

  You know, I bet you guys in the OGC on this list don't even have to ask 
how old some of us are, after you see us whipper-snappers quickly snap back 
with responses without thinking.
  I don't know if I would be considered young at 26 since there are 18 yr 
old CCIE's.
  I am on trying to travel down that scary road to CCIE too, sometimes I 
feel like I am in a Ferrari, then again sometimes when I come to subjects 
like ATM I feel like I am just learning how to ride my first bicycle.
  I love this stuff though.
