There's really not enough to go on.  You haven't said what type of
interfaces are involved or shown the configuration of those interfaces on
two sides of a link.  Are they Ethernet, SONET, Frame-Relay?

My guess is that you don't have your ospf network type correct on your
interfaces, but without seeing interface configs *and* your ospf router
config, it's impossible to tell.

Hi All,

To informally permit employees to watch the upcoming soccer world cup
without consuming all the bandwidth through the use of web TV, one of my
customers came up with this requirement:

They want to subscribe to a soccer web TV channel and access it over the
Internet by a dedicated PC or server. Then users connect to the server via
their browsers or provided client software to watch the soccer matches in
real-time. In that case, only the server consumes bandwidth.

What would you recommend? Thanks.

[c-nsp] ASA 8.3

2010-05-12 Thread Ivan

Hi All,

Shortly I will be deploying some new ASAs and came across the 8.3 
release.  I didn't expect that a minor release would have quite so many 
fundamental changes.  Without looking at the release notes, migration 
notes 
(http://www.cisco.com/en/US/docs/security/asa/asa83/upgrading/migrating.html) 
and various blogs etc on the Internet I would have expected things to be 
not too different than 8.2 which I have used recently.


I would appreciate any feedback from those who have deployed 8.3 as a 
new install or migration.  I will eventually have to decide if it is 
better to stick with the known 8.2 or the new 8.3 (new features and new 
bugs) to save the pain of an update later.

Re: [c-nsp] Unicast Reverse Path Forwarding - Loose Mode

2010-05-12 Thread Youssef Bengelloun-Zahr
Hello List,

Let me bounce on this thread again as I am seriously thinking
about implementing uRPF loose mode / RTBH on our backbone. We have been
taking on some DDoS recently, Internet is a bitch ;-)

I was thinking enabling it on the interfaces towards my :

- Upstream Providers,

- Peerings,

- Virtual-template Interfaces (my clients connect on a bunch of LNS using
PPPoATM).


We have a bunch 6509s acting as core routers and a bunch of 7204VXRs
(NPE-400 / NPE-G1) acting as LNS border routers.

Problem Is : I am concerned about performance issues. Is uRPF a big consumer
of CPU / Memory ?


Do you guys have ever experienced any particulars problems ?

Does activating this feature cause BGP or PPP sessions to flap ?

Thanks for the feedback.

Best regards.

Y.

 Agree.

   and I've never run into any situation where
   enabling loose mode has caused problems.

 The only problem we've had is when peering privately with
 other networks and you ask them to ensure they don't
 announce your prefixes to the general Internet (they should
 be kept only within their AS + their [BGP] customers).

 Well, what happens is that when they (mistakenly, I hope)
 announce your prefixes to the Internet, they become a
 transit path back to you. But because your private peering
 router does not hold a full table, inbound traffic from some
 soul on the Internet (who is not a customer of your peering
 partner) gets dropped because a route back to said soul
 doesn't exist in your peering router.

 There have been many a situation like this for us, and it's
 not pretty. Be watchful of your private (and public) peers
 when running uRPF.

 One could announce prefixes with a NO_EXPORT community to
 the peers, but this assumes they support BGP communities.
 Also, it could potentially mean your routes won't get into
 their BGP customers' networks (which is likely not what you
 want).

 Alternatively, one's peering router could hold a full table,
 but there's probably more to it than just simply that.

 Cheers,

 Mark.

On 6500, I believe the older sup2 has half the routing table capacity 
with uRPF enabled, but it's otherwise done in hardware.


6500/sup720 uRPF is free. There's no CPU/memory load.

The structure of NAT has changed so much that any non vanilla implementations 
are going to be very touchy.  If you're using a large pool of NAT exempt 
addresses and calling them from a object-group, this will be expanded per entry 
into statements like:

Nat (inside,any) source static new generated object network (not an 
object-group) new generated object network (not an object-group) destination 
static object-group name object-group name

So, seeing that for the first time might come as a surprise.  I ran into two 
NAT bugs during a migration with PAT and order of operations.  CSCtf89372 is 
one of them, which still is not fixed in the interim.   
A manual re-ordering of NAT rules fixes the issues, I thought Cisco had moved 
on from the PIX 6.3 days, guess not.

[c-nsp] circuit degradation/error simulator

2010-05-12 Thread Marcus.Gerdon
Hi all,

sorry for the not really Cisco-related topic, but the collected
expertise present on this list might once again be the solution.

For some testing I'm looking for a piece of software which is capable of
inserting various degradation and/or errors into a traffic stream.

The setup I thought of is setting up a PC with two NIC which passes
traffic between the interfaces. In the middle the software should be
able to generate packetloss, delay, jitter, fragmentation, reordering
and alike within the traffic stream passed on.

I didn't crawl through the depths of the internet dictionary (aka Google
:)) yet, but maybe someone can point to a piece to look at.

kind regards,

Re: [c-nsp] Huawei instead of Cisco

2010-05-12 Thread jgitau

Your biggest issue will be support and associated costs. they tend to
position themselves as a cheaper option in the begining but in the
long run you end up paying more for deployment, support, spares 
training (not easy to find guys with extensive Huawei background off
the shelf as you would with cisco + Juniper).

I run a mixed network Huawei NE40, NE-40E, NE80's and some GGSN's
based on the same platforms. Im happy with them but having worked with
cisco/juniper and Huawei and a few other vendors switching/routing
gear, I'd say go with cisco unless you have a budget for the enhanced
models (NE-40E and NE-80E - I have never had issues with this apart
from specialized applications that cisco won't have on a router
anyway) and or your environment is lighweight 

I however have to agree that they are slowly catching up and In a few
years I suspect I'll have changed my opinion.

Multiple vulnerabilities in Cisco PGW Softswitch

Document ID: 111870

Advisory ID: cisco-sa-20100512-pgw

http://www.cisco.com/warp/public/707/cisco-sa-20100512-pgw.shtml

Revision 1.0

For Public Release 2010 May 12 1600 UTC (GMT)

- -

Summary
===

Multiple vulnerabilities exist in the Cisco PGW 2200 Softswitch
series of products. Each vulnerability described in this advisory is
independent from other. The vulnerabilities are related to processing
Session Initiation Protocol (SIP) or Media Gateway Control Protocol
(MGCP) messages.

Successful exploitation of all but one of these vulnerabilities can
crash the affected device. Exploitation of the remaining
vulnerability will not crash the affected device, but it can lead to
a denial-of-service (DoS) condition in which no new TCP-based
connections will be accepted or created.

Cisco has released free software updates that address these
vulnerabilities. There are no workarounds that mitigate these
vulnerabilities.

This advisory is posted at

No other Cisco products are currently known to be affected by these
vulnerabilities. In particular, Cisco IOS Software is not affected by
these vulnerabilities.

Details
===

SIP is a popular signaling protocol used to manage voice and video
calls across IP networks such as the Internet. SIP is responsible for
handling all aspects of call setup and termination. Voice and video
are the most popular types of sessions that SIP handles, but the
protocol is flexible to accommodate for other applications that
require call setup and termination. SIP call signaling can use UDP
(port 5060), TCP (port 5060), or Transport Layer Security (TLS; TCP
port 5061) as the underlying transport protocol.

MGCP is the protocol for controlling telephony gateways from external
call control elements known as media gateway controllers or call
agents. A telephony gateway is a network element that provides
conversion between the audio signals carried on telephone circuits
and data packets carried over the Internet or other packet networks.

Multiple DoS vulnerabilities exist in the Cisco PGW 2200 Softswitch
SIP implementation, and one vulnerability is in the MGCP
implementation.

The following vulnerabilities can cause affected devices to crash:

  * CSCsl39126 (registered customers only), CVE ID CVE-2010-0601
  * CSCsk32606 (registered customers only), CVE ID CVE-2010-0602

Re: [c-nsp] circuit degradation/error simulator

2010-05-12 Thread Joel M Snyder

For some testing I'm looking for a piece of software which is capable
of inserting various degradation and/or errors into a traffic stream.

There are a number of open source tools (Dummynet, Wanem) with fairly 
basic capabilities.  You can also program your typical router for pure 
shunning; I have a Mikrotik attached to a rig on my desktop I'm using to 
simply choke a link down to 512K at this very moment.  These are good 
enough for a typical what happens when this happens kind of testing. 
Sometimes you need more interesting test environments, and then we use 
Shunra Virtual Enterprise (formerly Shunra Cloud, 
http://www.shunra.com/) and I've also used (but don't own) Linktropy 
(Apposite Technologies, http://www.apposite-tech.com/)

On 10/05/2010 08:34, Marian Ďurkovič wrote:
 LRM SFP+ is just part of the stuff you need. For LRM to work, the 
 switch linecard must have appropriate EDC functionality. If it's not 
 there, it simply won't work.

To give some back-ground on this, LRM is long-reach multimode.  As it's 
multimode, modal dispersion comes into play pretty quickly, and even over 
relatively short distances, it causes severe signal distortion - this is one of 
the primary distance limiting factors of multimode.

On xenpaks, x2 and xfp, the dispersion compensation is performed on the 
transceiver (by the EDC), and you end up with a fully digital signal being 
transmitted from the transceiver's electrical interface to the line card.
However as the SFP+ form factor is really tiny, there isn't enough room to 
house various components such as an EDC or a CDR (clock / data recovery).
For SFP+, these components are housed on the line card, if at all, and in many 
cases the line card simply won't have EDC.  Perhaps the n5k main board doesn't 
have EDC processors, which would make it unsuitable for LRM.

 (One more thanks to all people who thought that analog interface 
 between SFP+ and linecard is a good idea...)

Fibre and transceiver deployments are all about choosing the appropriate 
technology.  If you need to run fibre over longer distances, doing this over 
MMF probably isn't the best idea.  I appreciate that lots of organisation have 
cartloads of legacy 62.5µ MMF and that they tend to be unhappy about the 
prospect of changing longer runs to use SMF, but 62.5µ wasn't designed for 
longer runs at very high speeds.

In some senses, you might as well complain that SFP+ isn't physically large 
enough to house enough lasers for LX4.  10G standards like LX4 and LRM were 
only created to try to deal with legacy plant deployments which weren't really 
designed for anything more than 100M-FX.  Anyone sensible MMF deployment done 
over the past couple of years will have been OM3, where you can use SR 
transceivers instead of LRM or LX4.

If you need distances longer than 200m, LR + SMF is a better choice of 
technology to use.

[c-nsp] seeking an advice about PIM DM riddle

2010-05-12 Thread Roman A. Nozdrin

Hi all.

I have several 7604+RSP720+6704card(12.2SRC) installed in a ring 
topology as a core part of our network. There is a multicast source 
attached with one of that 7600 routers. The routers successfuly use PIM 
DM to distribute multicast streams over the  ring.
Here comes the riddle. There is a situation when an intermediate router 
don't graft several streams, that are pruned in that moment. The streams 
are always random. I noticed, there are no Graft messages in a log on 
the intermediate 7600. The reciver can get such streams at the end of 
prune interval only.
I steered multicast to another arc of the ring to observe the situation. 
The problem shifted to another router.
Here is the question, is there any hardware limit or a caveate I have 
missed concerned with the behavior I described?


I will appreciate any suggestions on the situation.

[c-nsp] PPPoE termination on ES+20/12.2(33)SRE1

2010-05-12 Thread Walter Keen
I'm trying to terminate 802.1q tagged PPPoE sessions on a 7600 with a 
ES+20G card.  PPPoE works fine, but large packets (ie: 1500 bytes) 
fail.  All MTU's are 9216 throughout the path until it hits the ES+20 card.


I did some initial work with this as a test on a 7200, hit the same 
problem, and the resolution was the use of ip tcp adjust-mss, however 
that does not seem to be working here.  I've tried it under gi2/1 as 
well, with no luck.  Doesn't seem to be an option under 'bba-group' for it


Of course adjusting the mtu on the client pc to something small, like 
1400 resolves it, but I'm looking at a mass migration of dsl customers, 
so that's not a feasible solution.


Has anyone run into this, before I open a tac case on it?

[c-nsp] 20 second packet delay

2010-05-12 Thread Raymond Lucas

Well, this was a new one for me.  One way packet delay of around 20 seconds
on a single link.  I had never thought it was possible, but just when you
think you've seen it all...

I have a customer with a number of sites, each with 2 x 3750 in a stack.
Each stack will typically have four ethernet hand offs to Ericsson
equipment which provides transparent circuits over microwave.  One member
of the stack will have two circuits towards one neighbouring site, the
other member will have two circuits towards a different neighbouring site.
The same microwave equipment provides all four circuits (potentially spread
across different line cards though) although with different dishes to
provide the appropriate directionality for the microwave.  Each circuit has
a single P2P VLAN configured on it.  This generally works fine.

Yesterday we had a very interesting scenario where at approximately 1200
the 3750s saw interfaces flapping on both circuits between two particular
sites.  From 1220, one of those circuits appeared to introduce delay in one
direction of 18-23 seconds.  This could be demonstrated with debugs of both
CDP and ICMP traffic.  The relevant interface at both ends were both
manually shut/no shut and also err-disabled/no shut due to UDLD detecting a
problem.

I'm pretty sure all interface up/downs were seen by the 3750s at both ends.
The microwave equipment is meant to relay up/down events that occur any
where in the path to all ethernet ports so that is expected regardless of
where the event actually occurred.  It is currently not clear if the
microwave equipment logged all those events or just the ones caused due to
UDLD or manual action.

Around 1500 we again saw interfaces flapping on both circuits between the
same two sites.  Around 1600 I checked the fault again and it had cleared.
My assumption is that it cleared after the flapping.

Ignoring the specifics of the up/down events and even if it was the Cisco
or Ericsson kit that was at fault, has anyone ever seen packets held up for
20 seconds across a link?

Cheers,
Ray

get the 5th and 6th card in the box.   One page on the Cisco site recommends
using the 2851 when terminating 6 T1s.  That same page also says the NM-2W
will not work in a 2851.  

 

Is there a replacement for the NM-2W or is there something like a
WIC-2DSU-T1v2 card available? 

 

 

I assume that by saying not supported that means it won't work at all, or
maybe it's It will work but don't ask us for support.

Re: [c-nsp] PPPoE termination on ES+20/12.2(33)SRE1

2010-05-12 Thread Dave Weis

On my pppoe virtual templates I have an 'ip mtu 1492' that would probably help.

Subject: [c-nsp] PPPoE termination on ES+20/12.2(33)SRE1

I'm trying to terminate 802.1q tagged PPPoE sessions on a 7600 with a
ES+20G card.  PPPoE works fine, but large packets (ie: 1500 bytes)
fail.  All MTU's are 9216 throughout the path until it hits the ES+20 card.

I did some initial work with this as a test on a 7200, hit the same
problem, and the resolution was the use of ip tcp adjust-mss, however
that does not seem to be working here.  I've tried it under gi2/1 as
well, with no luck.  Doesn't seem to be an option under 'bba-group' for it

Of course adjusting the mtu on the client pc to something small, like
1400 resolves it, but I'm looking at a mass migration of dsl customers,
so that's not a feasible solution.

Has anyone run into this, before I open a tac case on it?

 If you are looking for a commercially supported solution, there is a box

 (My understanding is that its just an embedded Linux box)

I've used Network Nightmare.  It works pretty well.  It really doesn't
do anything you couldn't craft up yourself from one of the free
opensource solutions already mentioned but if you don't want to be
bothered rolling your own appliance and just want something prepackaged
and commercial it'll do the job.  I did think the pricing was a bit
steep however.
