BSCI - 640-900 [7:42343]

2002-04-23 Thread [EMAIL PROTECTED]

I sat this exam in March.  You should be able to find my opinions of it in 
the archives - can't remember the thread name.  Basically, it follows the 
exam outline pretty well.  I haven't done the 640-503 exam, so I can't 
compare, but I reckon the BSCI was much easier than the old ACRC exam.

Exam objectives, in case you haven't already come across them, are here...

Hi all,

There's just one test missing for me for CCNP - which is routing. I was
thinking about the BSCI which opens a new path towards CCIP. Does anybody
know about the contents of this test ? Is it much similar to 640-503 ? 
Does
anybody know some good practice test ?

Thanks,

Paulo

RE: IVR for conducting phone surveys [7:42405]

2002-04-23 Thread Mark Odette II

Mike-
I have not, but if you find more detail on it off-line, I'd love to learn
what you do to accomplish this.

I've always wanted to know how you make the IVR connect with the backend
database (what's technically involved).

I used to work for a leading advertising company that used Unix and Windows
NT-based IVRs that worked with Dialogic Voice cards (Voice T1s connected
directly to the card), and the systems used a custom "carrousel" application
to run through the prompts.  The application would create a text file record
of all options chosen during each call, and then export or "roll" the log
file out for a remote process to come retrieve the log file and parse it
into a SQL DB.  And with that, they generated "call count" reports.

If Call Manager has a part of it that you can configure through a GUI to
"link" up with a back-end Database for doing a task such as the survey stuff
your talking about (which I assume would be both Voice answers and
Touch-Tone responses), that would be awesome.

Mark

Subject: IVR for conducting phone surveys [7:42405]


Hello all

Has any ever used or have any information on using Call Manager and it's IVR
functions to conduct phone surveys?  Perhaps with an ODBC or Oracle
back-end?

The place I'm working uses phone surveys fairly often and wants to use them
more often. But they're expensive (they pay someone for the service).  Just
from what I've seen, we could easily buy a full Call Manager setup with IVR
functionality some servers for database and save them a TON of money and
they could conduct surveys to their hearts content

Any info is greatly appreciated

Thanks!

I enquired about this with the CCIE Team. They explained the beta runs to
May 7th, after that time it will take serveral weeks to evaluate the exam
and results. I'd say the new exam will take effect in about 6-8 weeks.

I will be sitting the old one

I have an OSPF connectivity problem.  I have 3 routers as follows:

EIGRP - Reliability and Load Dynamic? [7:42406]

2002-04-23 Thread Kevin Jones

Hello everyone,

I have a question that I have been struggling with for quite some time.  Are
the reliability and load metrics in EIGRP (or IGRP for that matter)
dynamically learned?  If so, why do we manually assign values like we do for
bandwidth and delay.  I have searched numerous Cisco white papers and have
found only one article where it mentions the two as being dynamically
learned.  Since I have not found any others that mention it, I am starting
to feel that the one article is a typo (or I am just not understanding it
the way it is worded).  I would think that if they were dynamically learned,
then there would be more information about the process.  No other routing
protocol is able to detect such statistics on the fly (to my knowledge).  I
understand that dynamic detection might not be a good thing, esp. if the
reliability and load were constantly changing, but never-the-less there
should be more info somewhere.

If you can find more than one specific white paper and lead me to them, I
would appreciate it.

Thank you,

Does an instance found under 1.3.6.1.2.1.2.2.1 exist that corresponds to the

If so, what is the value found in 1.3.6.1.2.1.2.2.1.5 for that instance_ID?

It might be constructive to compare that value to the ones found in

Re: PIX and AAA [7:42302]

2002-04-23 Thread nrf

In such a situation, authorization would be achieved by writing a bunch of
access-lists on the Pix.  Then, you designate those particular access-lists
within the radius server for individual users.  For example, let's say you
have a user called billclinton, and you want to restrict his access to
certain websites.  So you write an access-list that does that, and then in
his radius profile, you "call" that access-list.

This works when you are doing straight authentication through the Pix
directly.  I have never tried it through a VPN.

Re: Layer2 Layer3 or Hardware problem? [7:42391]

2002-04-23 Thread Ronnie Higginbotham

Joe,

  I had the exact same problem but in a larger environment. Some client on
one subnet would get disconnected while other did not. After hours and days
of troubleshooting and this is what we found out.

1.) As400 needed some PTF files applied for the TCP/IP stack (Basically
applied patches to the AS400)
2.) Also the NIC on the 400 was running 2 frame types 802.2 and 802.3. What
we found in the sniffer trace was the AS400 would send out a 802.3 frame
every once and a while and cause the switch to re-arp and client would lose
the telnet session to the 400. I cannot pin point a single client or segment
I did not know how it dropped this person and not this one. Once we remove
one of the frame type to stop the re-arp. No more problem. No I cannot say
the PTF applied to the 400 did not fix the problem also.

Some thing to look at. I am curious to see if anyone else has had a problem?

RE: PIX and AAA [7:42302]

2002-04-23 Thread Darren Mitchelmore

NRF.

I am just about to setup a PIX 515 with the Cisco VPN client and the ias (
WIN2K RADIUS SERVER ). From my understanding the VPN client has a group
login then the user will be prompted for a username/password that the 
PIX will pass to the IAS server using Radius. That will be authenticated
against the Win username / password database (used to be called SAM ??) on
the IAS server. 

I believe that this is authentication. Not sure how authorisation is
achieved. How do you tie in the access-list 
to that individual user ??

Is this the setup you have got going ??

Do you have any problems implementing it ??

PS - I have setup PIXs before but only with simple policies...

Darren M

Re: access-list performance degradation [7:42327]

2002-04-23 Thread Michael L. Williams

Agree with the first response post. there's no definite answer.
depends on the amount of traffic going through etc...

However, what interested me is that you said that most of the packets match
the last entry.  Do you mean the last access-list entry you enter or the
implicit deny at the end?

Just curious.

Your best bet is to jam traffic through your router (access-list) and do a
'show proc cpu' and see what the load is on the processor.  A "cheap" way to
measure the delay would be to ping through the router to a destination on
the other end with no traffic going through it, then attempt the same ping
to the same destination while loading the router down with traffic and see
what the difference in the results are.

RE: OT - VPN and use of public address space [7:42362]

2002-04-23 Thread Mark Odette II

Interesting question you bring up!

For my exposure, it has only been setting up VPNs between company locations
that are taking advantage of Frame Relay or xDSL connections to the Internet
and then VPN-Connecting those regionally-separate offices.  In these
situations, they are using RFC 1918 addresses on their private networks, but
are having to use the Public addresses for end point to end point
termination of the VPNs.  Keep in mind though that these same scenarios have
been done with the customers only being given between 5 and 30 usable
addresses at each site for their Public blocks to NAT with.

Subject: OT - VPN and use of public address space [7:42362]


For those of us that work for NSPs/ISPs or some other form of provider
functionality, what are the thoughts in regards to use of public address
space within VPNs?

I've seen several networks that are using public address space within their
VPNs, hence preventing the use of that space on the net. Several clients
have large netblocks routing in their VPNs rather than renumbering to RFC
1918 address space. To me, this seems like a horrible waste of address
space. I'd tend to think that it would be the provider's responsibility to
strongly encourage the clients to relinquish their public space if all
traffic is to remain in the VPN. Using NAT to allow Internet access as
required. Also, I thought I had heard (perhaps just a rumor) that ARIN or
some other similar authority watches for use of address space. In other
words, if someone's been assigned a /16 and no hosts of that /16 are
publicly visible, a 'nasty-gram' would arrive questioning the lack of use.

Sorry for the off-topic thread but since I've seen several people post
questions about building VPNs, I was hoping to see some discussion on the
matter.

Layer2 Layer3 or Hardware problem? [7:42391]

2002-04-23 Thread Joe Morabito

Hi all.  I have a real world problem and would like some thoughts, here it
goes.

Client has a central site with 7 remote locations.  Central site has a 6513
with MSFC2, all sites have T1 in.  Eigrp is used between sites and is fine.
At the central site lies an AS/400 that all remote sites connect into (users
use IBM client access).  All is IP no SNA anywhere.  What happens is at one
and only one location users get bounced out of there session about 4 or 5
times a day.  They have full connectivity to the central site, just no
AS/400.

So I was at the remote site where the problem exists, could ping the as400
fine.  So I waited for a "blackout", it came.  When the users were bounced I
tried to ping the as400 and was unsuccessful.  I tried to ping the central
router and was good, I tried to ping the vlan ip address that the as400 was
in, that was good.  I even tried to ping other computers in the same subnet
as
the as400 and that was good.  Tried to ping the as400 again and that was NO
good.  These outages only last a couple of minutes and then it comes back up.

There is NO route flapping.  All eigrp neighbors stay put and all routes stay
put.

What is really strange is that this happens only from one remote location,
all
other locations are fine.  The as400 has only one NIC (ehternet) and all
other
sites connect to the same IP address.

So where is the problem?  I checked the port the as400 was plugged into and
found some errors, I found out that the port was set to 100/full and the
as400
nic was set to 100/half, so I adjusted the port on the switch to 100/half.
But if this was the problem, wouldn't all sites have trouble?  Could the
switch possibly be aging out its cam table to the remote site that is having
problems?

I don't remember if they blacked out again after changing the duplex (I had
been staring at debugs for about 8 hours).

I called TAC and bumped up the outbound queue size to the site that is having
problems, but haven't had a chance to call them back.

Any suggestions?

Thanks.

-Joe

Re: frame-relay [7:42350]

2002-04-23 Thread [EMAIL PROTECTED]

I think the reason no LMI sent/received is showing is because he's turned 
keepalive (LMI) off.
But what's this service connected to?  If it's a frame relay service from 
a telco, start talking to them.  Have you configured the correct type of 
LMI?  Have they finished provisioning the service properly?  If you aren't 
even talking to the FR switch correctly, it doesn't matter much whether 
your PVCs are provisioned correctly. 
Try turning your keepalives back on and debug frame lmi.  You should see 
LMI packets being sent from your router to the switch, and being received 
by your router from the switch. 
If this is a lab setup where you've configured the frame relay switch, 
then start looking at your configs for the switch.

Re: data vs voice traffic [7:42324]

2002-04-23 Thread Michael L. Williams

You can only apply traffic-shaping to outbound traffic..

The best you could do is setup policing to limit incoming traffic..

http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/12cgcr/qos_c
/qcpart4/qcpolts.htm

(watch for URL wrap)


To get to you question, Ira, voice traffic should be using RTP protocol, so
you can differentiate between voice and regular data using that fact.  There
are different queueing methods you could use, i.e. you could setup a
Priority Queue with voice traffic having the highest priority (even at the
expense of other traffic), or you could setup LLQ that has a strict priority
queue for voice and then uses CBWFQ for the rest of the data (if you define
any other classes).

Although this document is called "Congestion Management", it covers
virtually all of the queueing methods you may want to use for your purpose.

http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fqos
_c/fqcprt2/qcfconmg.htm

(again, watch for URL wrap)

Depending on the bandwidth of the WAN link (if it's under 2Mbps), then WFQ
is enabled by default.  You should be able to use the 'ip rtp priority' to
configure a strict priority queue for RTP (voice) traffic.

Also, depending on the bandwidth (if its less than 768Kbps) you'll want to
(need to) use some kind of Link Fragmentation and Interleaving (LFI).  If
your WAN connection is Frame Relay, you can use FRF.12 to do this, although
check the archives and you'll see people had problems getting it to work as
advertised (there was simple solution but I can't remember it offhand).
However, the other method for LFI is to configure the WAN link as a
Multilink PPP connection (even if it's only one line) because Multilink PPP
has a LFI facility built-in.  The reason you want LFI on links less than
768Kbps is because smaller (40-80byte) voice packets can be delayed too much
when they get in the queue behind a 1500 byte packet of regular traffic
(because of the slow speed, the serialization delay for 1500 byte packets
get large).  Here are some links to help you get started.  (watch for URL
wrap on any of the below links)

If your IOS supports it, you can configure a service policy within your
frame relay map class, and specify WRED or RED within it.  Take a look at
CBWFQ on CCO, it may be what you are looking for.

RE: Access-list Assistance Needed [7:42351]

2002-04-23 Thread Chris Charlebois

First off, you caught a typo.  That should have been 198.x.x.5, not
192.x.x.5.  Secondly, going back to your first reposte... from your original
post, it was not clear that the 198.x.x.x was being routed to you from the
ISP.  Ideally, you would have a /248 address space from the ISP, so you can
assign one to the remote router, one to the local router, one for overloaded
NAT, one for the static NAT, and still have 2 addresses let over.  I agree
the secondary address is something of a cludge.  On reflection, I suppose it
is not needed; the router *should* respond to the 198.x.x.5 address if there
is a static route from the ISP.

Oh, and overload to the interface is the same as overload to a pool of one,
which is what we want, correct?  When the interface is used (instead of a
pool), it simply uses the ip address of the specified interface.

Re: data vs voice traffic [7:42324]

2002-04-23 Thread Chris Charlebois

You can use QoS to prioritize traffic outbound, but unless you have control
of both ends (you made it sound like this is a connection to an ISP), you
can't prioritize traffic inbound.  Sure, you could setup traffic shaping on
the inbound connection, but that would just be closing the barn doors after
the cows have gone.  If you need prioritization, you need to talk to your ISP.

Re: Security advice - opening ports other than 80 [7:42333]

2002-04-23 Thread Chris Charlebois

I agree with Sam.  You can (and should) limit access as much as possible; if
server A needs TCP port 100 open, then TCP port 100 should *only* be open to
server A's ip address.  That way, the only packets that get it will be
dropped into the waiting arms of your vendors program.  And if there's a
security issue there, you will know who to talk to.

You want to make sure you know what ports can get in to what addresses, and
what applications are listening at those ports.  That will give you a list
(hopefully short) of application you need to keep updated with security
patches.

RE: Access-list Assistance Needed [7:42351]

2002-04-23 Thread JunoGuy

I appreciate your assistance.  Assuming that this the secondary interface is
required.  Can the same be achieved by overloading to a POOL instead?  I
dont understand why you need to have a secondary IP address when the ISP is
already routing traffic to the 198 subnet.


Also, say that traffic reaches the router that is intended to go to the
PCa.  I see that your access-list states:

access-list 102 deny tcp host 192.x.x.5 any eq 0 
access-list 102 deny udp host 192.x.x.5 any eq 0 


Why do you specify the internal PCa address versus the global address that
it is using?  Does this mean that IP nat statements are looked at before
access-list deny statements are?  Thanks for the explanation.

RE: access-list performance degradation [7:42327]

2002-04-23 Thread Chris Charlebois

I don't have a definitive answer, but there are facts that come into play
that you haven't revealed.  First of all, there is no definitive answer. 
What you are looking for is a "Yeah, it'll work fine" or a "You'll run into
serious problems".  That depends alot on what you're doing with the line and
the router.
- If you are handling 90% ftp and http traffic, the cpu delay won't matter. 
If you are running VoIP or VidoIP, that delay could put you over the
recommended limit and effect quality.
- If the utilization of the line is low, the extra queuing probably won't
matter.  If you are overloaded the bandwidth, queuing becomes critical.
- If the router is just routing packets, and hence has low cpu utilization,
the extra cycles won't be missed.  If it's running BGP, NAT, and auditing,
you'll probably hit a snag.

And you also didn't specify what kind of access list it was.  Extended
access lists use alot more processor cycles than standard lists.

All this being said, I find it hard to beleive that the list cannot be
adjusted to optimize it a bit.  I assume you have taken a look at the "show
ip access-list" command to see what rules are getting hit the most.  If you
need help optimizing it, post the output for that command here and we can
help.

RE: OSPF over ISDN demand circuit [7:42348]

2002-04-23 Thread Kage Roc

I have seen this b4 when I configured Demand circut.  

First of all, OSPF will attempt send an update accross that ISDN line when
somthing changs in the ospf database.  So my guess is somthin is changing in
the database (i.e.  a route flap)   Now, when I had this problem the router
that was running OSPF /w demand circut and intiating the ISDN call was
Mutally redistributing between 2 protocols (ospf and igrp)and because I was
using a classess RP, IGRP, and running the same major NET on the eth and
ISDN, IGRP was adv. the ISDN network.   I was also running PPP over the ISDN
link.


Here was my problem: 

OSPF dials the adjacent router to update.  When a PPP session is estab. a
host route gets installed on both PPP talkers (it's just the way PPP works
do ask me why)

When OSPF is done the BRI will go down. Here is the fun part :) That host
route dissapears so that route is pulled from the ospf database  adn from
IGRP, but IGRP redistrbutes back to OSPF that the host route is gone and the
MAXAGE of the OSPF DB changes and that is why OSPF dials again.  The way
that cisco recommends fixing this is to filter that host route from being
redistributed into OSPF.  That should fix the problem.  I hope this helps :)

Or generally just protocol 50.  Because after all, how many people really
use AH?  Even the standards bodies are thinking of dropping AH because it
really doesn't do very much - ESP can also do authentication, and while AH
does also does authentication of parts of the packet header, is that really

Jenny,

One workaround that I'm aware off is to use CB-WFQ and create a simple
default class with WRED queueing enabled within your policy map.  From
there, you just need to add the policy map associated with the CB-WFQ to
your frame relay traffic shaping class and that should be it..

First of all, this won't work, unless you have the 198.x.x.x subnet setup as

have to be available to the outside interface of the NAT router.  If you

I need help with a BVI and MIBs on a Catalyst 8540 [7:42370]

2002-04-23 Thread SNMP2002

We have an Catalyst 8540 with a BVI.
There are numerous ports on the switch that are in this bridge group.
If you look at the BVI interface,
sh int bvi2:

MTU 1500 bytes, BW 1 Kbit, DLY 5000 usec, rely 255/255, load 1/255

The true speed of the devices plugged into the ports is manually set to
100Mbps. But
using our network management software which reads the MIB in the switch
interfaces,
it reads the devices as a speed of 10Mbps.  I think the MIB is using the
data from
the BVI (BW 1 Kbit) and not the real port/interface speed.

Does the BVI2 have a true speed of only 10Mbps?  What would it do to change
the
BW from 1 Kbit to 10 Kbit (10Mbps to 100Mbps) manually?

Thanks for any ideas.

content of the questions is GOOD, compared to the rest. Also the service I 
enjoyed as an european from ccbootcamp sofar has been GOOD.

The reason I post is because I maybe can help the listmembers help choosing 
the right gear for their quest.

>>
To straighten out a misunderstanding, I was not having problems with the 
registration, but with the engine as a whole.

After about 30 mcp and ccxx cert's, beta's for selftest and as an ex- mcp 
trainer, I hope can say the engine is not what it supposed to be.

THE OPPOSITE of what is one the inside of the book, thanks to you.

Monday I graduated the old written (tried the 351 Friday, is a huge one), 
with a little luck but lots of hard work.

Have bought my set of 4 foot green cpress books, some discounted because of

I'm sorry that you had problems with the CD that came with the book.  I
understand this has been a problem for many people. I was not aware the

so much work to get the license activated, and I've asked them to change
this for any future projects we do together.

I did notice that the Boson exam you registered is an older one, and I would
recommend you take advantage of the free download to update your questions.
The newest version will have over twice as many questions, and have a lot of
early bugs worked out.  To get the update, simply download the newest
version from the Boson page and it will install automatically and your
licensing should be maintain.  If it gives you any trouble, please feel free
to contact either [EMAIL PROTECTED] or myself.

Lastly, I maintain a webpage with some documents specific to the 350-001

BGP:neighbor soft-reconfiguration inbound [7:42367]

2002-04-23 Thread cebuano

Hi gang.
Please clarify this for me. On CCO it states...
To generate new inbound updates from stored update information (rather than
dynamically)
without resetting the BGP session, you must preconfigure the local BGP router
using
"neighbor soft-reconfiguration inbound".
Is this generating inbound updates "internally" from RAM? What is it
referring
to regarding
"dynamically" generating new inbound updates?
So when i do a "clear ip bgp *"  this defaults to a soft-reset since the
above
command has
been preconfigured on the routers?
I can't test this right now since I've taken down my rack in preparation for
the move this
weekend.
Thanks in advance.

Elmer

RE: OSPF over ISDN demand circuit [7:42348]

2002-04-23 Thread Blair, Philip S

Are you trying the setup the circuit to use Dial on Demand Routing (DDR),
such that that circuit only comes up when needed then disconnects? If so,
what are you implementing?

backup interface?
floating static?
dialer watch?

Depending on your implementation of DDR you need to adjust your interesting
traffic (dialer-list).

Hi, Group,

On an ISDN circuit running ospf , if I want to use "ip ospf demand-circuit"
to keep it from being brought up by ospf update, do I need to define
224.0.0.5 as non-interesting traffic in dialer-list?

I have configured "ip ospf demand-circuit"  on one side of the ISDN, but
routing update to 224.0.0.5 keeps activating the circuit?  What is the
problem?

Thanks

Take it for what it's worth, but I've had this happen to me in the past and
it usually came down to a hardware issue, meaning the cable and/or interface

OT - VPN and use of public address space [7:42362]

2002-04-23 Thread Kane, Christopher A.

For those of us that work for NSPs/ISPs or some other form of provider
functionality, what are the thoughts in regards to use of public address
space within VPNs?

I've seen several networks that are using public address space within their
VPNs, hence preventing the use of that space on the net. Several clients
have large netblocks routing in their VPNs rather than renumbering to RFC
1918 address space. To me, this seems like a horrible waste of address
space. I'd tend to think that it would be the provider's responsibility to
strongly encourage the clients to relinquish their public space if all
traffic is to remain in the VPN. Using NAT to allow Internet access as
required. Also, I thought I had heard (perhaps just a rumor) that ARIN or
some other similar authority watches for use of address space. In other
words, if someone's been assigned a /16 and no hosts of that /16 are
publicly visible, a 'nasty-gram' would arrive questioning the lack of use.

Sorry for the off-topic thread but since I've seen several people post
questions about building VPNs, I was hoping to see some discussion on the
matter.

-chris

RE: frame-relay [7:42350]

2002-04-23 Thread Nikolay Nikolov

Usually this indicates problem with encapsulation or hardware (interface or
cable).

1. Check on the frame-relay router, if you are using right encapsulation:
frame-relay IETF !!!
2. Try switch to the second serial interface on your the router and see if
the problem persist.
3. Try using HDLC encapsulation (the default one) and connect the serial
interface to the router with a good serial interface. (Don't forget to set
up clock rate on one of the end with DCE cable!!!)
 Debug interface: #debug serial interface
 The myseq, mineseen and yourseen should read the same. If not try using
different cable.
If the line protocol still goes up/down you have bad Serial interface on
your router.

Actually on ALL platforms, ACLs are fast or CEF-switched by default.
You can use netflow feature acceleration on models and IOS releases
that support that as well.  ACLs have been fast-switched both inbound
and outbound since IOS 10.0 (quite a ways back :)
Policy routing has been fast/CEF-switched for several major releases.

Yes, ACLs cause impact and yes, how deep it has to search for a match
does make the difference.  So the only true answer is to benchmark a
case with typical traffic mix both with and without the ACL.

The final solution is to use turbo ACLs or Cat6500 ACLs.  The former
finds a match in three lookups for any length ACL.

The one action that does cause IOS process CPU time is the generation of
an ICMP administratively prohibited unreachable message sent back to
the source.  That's why those are rate-limited to one/sec per source.
And you can disable them entirely to prevent a DoS with "no ip unreachables".

RE: Security advice - opening ports other than 80 and 443 in[7: [7:42356]

2002-04-23 Thread William Gragido

Do you load balance traffic to your fire wall(s)?  If so, what methodology
and more importantly, whose technology are you using.  For example, if you
were utilizing Foundry Networks ServerIronXLs and are employing a sandwich
architecture, you could not only switch based on the protocol and in effect
load balance all port 80 and 443 traffic to different devices respectively,
you could also provide nimda/code red (sic Trojan) mitigation.  I believe
that Cisco's CSS switches will allow you the same functionality but am not
quite up to speed on that gear. Security Policies gain legitimacy through
actions.  Your Security Policy and Procedures should act as a point of
reference to for your Rulesets, however it will be up to you as the
administrator, working with your ITSEC team and business units to define and
streamline your identify the types of traffic you will need to allow entry
and exit from your network in order to maintain normal business conditions.
Remember the more complex a solution is, the greater the risk due to
learning curve, configuration etc.   you are concerned about Worms and
viruses infiltrating hosts within or past a zone/dmz you may wish to explore
not only Network Based Intrusion Detection, but Host Based as well.

You could have some duplex mismatches. Do a clear counters then do a show
int  awhile later. Look for collisions and input output errors. There
shouldn't be much, look for high errors rates. Then play with duplex/speed
settings then check for errors again, maybe you may need to replace a couple
cables to reduce errors.

IP Forwarding [7:42353]

2002-04-23 Thread Chris Headings

Not sure on this, but can't you have a router take a packet destined for one
location, take and forwared it to another location based on a mapping or ACL.

For example, all requests that come in a serial interface destined for
10.0.0.15 can be forwarded to 10.1.1.10 without the requesting station
knowing the new destination IP?

We need to make some pretty large DNS changes and would like to use this in
order for the DNS fairies to take their time to do their propogation.

Thanks!

Chris

Or generally just protocol 50.  Because after all, how many people really

does also does authentication of parts of the packet header, is that really

PC IP:  192.168.10.5
LAN Address:  192.168.10.0/24
Serial: 200.x.x.1/30


There are many other PCs on the LAN but only one of them (PCa) is running a
specific program.  I would like to be able to translate PCa to a unique
global IP address (lets use 198.x.x.5) and have all the other LAN traffic to
get overloaded / translated to the serial IP address on the router.

In addition, I would like to redirect all incoming traffic destined to
198.x.x.5 (PCa Global IP Address) with ports greater than 0 (for both UDP
and TCP) to the PCa internal 192.168.10.5 IP address.

Please help.  TIA!

OSPF over ISDN demand circuit [7:42348]

2002-04-23 Thread Ruihai An

Hi, Group,

On an ISDN circuit running ospf , if I want to use "ip ospf demand-circuit"
to keep it from being brought up by ospf update, do I need to define
224.0.0.5 as non-interesting traffic in dialer-list?

I have configured "ip ospf demand-circuit"  on one side of the ISDN, but
routing update to 224.0.0.5 keeps activating the circuit?  What is the
problem?

Thanks

Well, actually, the Pix does support a very limited amount of Radius
authorization.  It's only for users going through the Pix, not
administrators of the Pix.  And the authorization 'capabilities' only allow
you to invoke existing access-lists on the Pix for certain users, so, like I
said, it's very limited.  Still, the capability exists.

Re: What are the first thing you do...?? [7:42276]

2002-04-23 Thread Priscilla Oppenheimer

You did the most important thing, enabling portfast. That will speed up 
performance on startup. Also check for a duplex mismatch problem on every 
port. You may want to hard code everything as full duplex, (assuming the 
ports just connect a single device). Don't rely on auto-negotiation since 
it doesn't work a lot of the time. (On the other hand, there are cases 
where auto-negotiation works better than hard-coding, so do some testing 
first.)

Keeping STP enabled shouldn't be a problem. It's the safest thing to do 
unless you are absolutely sure nobody is going to add any switches to the 
network in a redundant way. It's hard to ensure that. These days if you 
order a hub from some vendors, you get a switch anyway. End users could 
order a hub to add devices somewhere in the network and actually get a 
switch and possibly cause problems.

STP won't affect the routers unless they are configured as bridges, which 
they probably aren't.

STP does send BPDU packets every two seconds, which some people could 
consider a performance issue. These packets go to a multicast address. A 
good network interface card (in end devices or routers) will ignore those 
multicasts and not interrupt the CPU. Unfortunately, not all PC NICs are 
that good.

Regarding testing the performance, do you have any before and after stats? 
How was the performance before you swapped out the hubs and put in 
switches? Maybe it was never so hot to start with.

On the other hand, it is possible that the servers actually liked being in 
a shared Ethernet environment and are overwhelmed by a switched 
environment. In a shared environment, contention for the medium would slow 
down the requests to the server. Now the server may be getting requests 
much more quickly than before. What is the CPU on the servers?

What protocols are you running? TCP/IP or IPX/NCP or NWLink (Novell's 
NetBIOS?) With TCP and NetBIOS you can often prove that the problem isn't 
with the network if you have a Sniffer. You can show that the server ACKs 
quickly but then takes a long time to process requests. If ACKs are getting 
through quickly, then the network is OK.

BSCI - 640-900 [7:42343]

2002-04-23 Thread Paulo Cesar Buerger

Hi all,

There's just one test missing for me for CCNP - which is routing. I was
thinking about the BSCI which opens a new path towards CCIP. Does anybody
know about the contents of this test ? Is it much similar to 640-503 ? Does
anybody know some good practice test ?

Thanks,

Paulo

Thank you, Kevin.  While people are waiting for my new book, the 
final proof pages for which arrived this morning, I have some other 
suggestions.  Mine will be out sometime in June, although I don't 
have the exact date.

Those of you that have not dug into the Cisco Press "Inside IOS 
Architecture" (IIRC the title) really should.  A complementary book, 
which I recommend highly, is Alex Zinin's "Cisco IP Routing" from 
Addison-Wesley.

Alex is a CCIE/CCSI, and was in tier 1 ISP support at Cisco, between 
TAC and engineering. He's at a new company now.  Alex is also 
co-director of the Routing Area of the IETF, so he's in the heart of 
the new action.  I know him, and he's also a nice guy.

This book goes into the same sort of depth on the Cisco router 
control plane (i.e., routing protocols, routing table) that the 
Inside IOS book does on the operating system and forwarding. It's the 
first published (admittedly pseudocode) descriptions of the actual 
data structures of the various routing tables, the logic of the 
routines updating it, and the actual logic of redistribution.  Highly 
recommended.

I've always wanted such a book available when writing mine, because I 
have chosen to focus on the use, rather than the implementation, of 
the routing protocols.  I suspect this will answer a lot of the "why" 
questions about redistribution and the like, if you lack, like most 
people, a background in protocol development and can make good 
guesses!

I've seen STP cause problems with clients at bootup.  Some clients boot too 
fast for the switch and then don't receive a DHCP address.  Pretty soon 
people are yelling that the network is down.  However, you say that you've 
enable portfast on the client ports, so that should prevent the above 
described problem.
Can you provide more detail regarding the bad things you've been hearing

They can do more than just bring the server down. They can gain control of
the server and have it attack other servers on your network or outside
network. ex. the IIS code red worm only needed port 80 to be open on
Winblows servers to spread across the internet.

Re: Security advice - opening ports other than 80 and [7:42333]

In my case, a third-party application requires port TCP 100 open. I used a
conduit from the PIX allowing in/outbound traffic to that specific server IP
address where the application resides.

My question is, how can I make sure this TCP 100 port is going to be secure
as possible... I would like to know what kind of threats I would face with
that port TCP 100 open and how I could minimize those threats.

Try to find out exactly which ports are needed, allowing all IP is 
dangerous.  In terms of what the vendor said about only that box being 
affected- the hacker can gain control of that box and possibly have his way 
with your network from there or use you to spread his treachery.  Key is to 
find out exaclty what is needed and allow nothing else to even reach the 
box.

RE: Remote access [7:42310]

2002-04-23 Thread Don Nguyen

If they can't use or a VPN solution is not viable you could look into a
virtual modem bank from a telco that services your area.  I used this as a
solution for a customer that needed dial-up access.  Basically you buy say
50-100 virtual modem lines(unless of course you think all 500 remote users
will be on simultaneously, this should give you a modem line/remote user
ratio of 10-1 to 5-1).  The telco handles the calls and you can give a
single number to your remote users.  They route this traffic to your
router/access server where you handle the authentication and access, usually
thru an ATM pipe.  However, I would recommend trying a VPN solution solution
if possible first.

RE: Security advice - opening ports other than 80 and [7:42333]

2002-04-23 Thread Don Nguyen

Its generally a good idea only to open ports that necesarry (eg. 80 for
http, 21 for ftp, etc..).  Opening up unnecesarry ports and/or running
unnecesarry services just opens your server up to security vulnerabilities. 
In your case I don't really understand what you're trying to do.  For a web
server using SSL you only have to allow inbound traffic to port 443, you
don't need port 80 open unless it also serves up unencrypted pages.  If you
want/need to use IPSEC you will need to allow inbound traffic on the UDP
port 500 and allow IP protocols 50 and 51(not ports 50 and 51).

The software vendor argues "that the worst scenario could be that hackers

 Is that true  ?

How risky is that to my network ?  I would like to secure that connection

I was hoping to get by with minimal ATM but I gather from what you say that
the
interworking of MPLS and ATM is considered a necessary part of the
ceritification.

According to the exam page, CEF is a topic to be tested. I have the
Pepelnjak/Guichard
book ("MPLS and VPN Architectures") but not the one by Alwayn ("Advanced
MPLS Design
and Implementation"). Pepelnjak and Guichard mention that "the CEF switching
mechanism
is a necessary prerequisite for successful MPLS/VPN data forwarding as label
imposition
is achieved through the CEF switching path" (p. 188). I can only guess the
details.
Were they discussed in the Alwayn book? If not, can you refer me to a
website or other
publication for details about how CEF supports MPLS?

I have a question to try and straighten out source route transparent bridging
r1 and r2 are connected to a 3920
r2 and r3 and connected by a cat5

--- - ---   ---
   trcrf2trbrf 1 trcrf2bridge group 10
tr V/ring 1000

In the scenario above when we are using soure route transparent bridging
the trbrf is 1 , the trcrf is 2 and the ethernet bridge group is 10.

There is a Token ring Virtual ring of 1000 configured using source-bridge
ring-group 1000

All numbers are in decimal!

If I configure source-bridge transparent 1000 1 1000 10 I need to know if
the first 1 in the config line is mean't to refer to the trbrf number
confgured on the 3920 or is this just an arbitrary number to link the token
ring source-bridge ring (1000) to the ethernet virtual ring (1000) in order
that they can both talk.

Hope someone can clear this up for me

You can not redistribute the default route into OSPF.  You MUST use the
"default information originate" command in order to redistribute a static
default route into OSPF.  Every other route (non-default) will be

Hi all,
as you already suspected, the #13 is the ifindex number. Actually I dont
know the principle how the ifIndex can be converted into the pysical port.
But I know an OID string, where you can ask the device to return the
physical port name to a given ifIndex.

So Bill, try to ask your 2900XL using snmpget and the OID
1.3.6.1.2.1.31.1.1.1.1.X where X is the ifIndex.

I just tried it on a 2924XL and got the following reply:

snmpget 10.0.10.5 1.3.6.1.2.1.31.1.1.1.1.13
SNMP++ Get to 10.0.10.5 SNMPV1 Retries=1 Timeout=100ms Community=public
Oid = 1.3.6.1.2.1.31.1.1.1.1.13
Value = Fa0/12

Hope this helps

I passed it.  Just read the 2 Cicso books, know ATM well, and use every

I hear that Foundry's MPLS is better though

Has anyone found a site where
there are any practice exams. Any help would be appreciated.  Thanks.

The pix does support radius.  I am using it for a small client to
authenticate PPTP connections using the Microsoft 2000 Radius server.

Hi Mike,

As you already assuming, deleted subinterfaces will be reported by a sh int
command until the router is reloaded. Similarly, removed hardware interfaces
will be reported as "removed" until next router reload.

Bye, Peter
