Looking for an IPv6 naysayer...
by Stephens, Josh 12 Mar '11

12 Mar '11

Not something I'd typically use this list for but I have an opportunity to host a debate of sorts on IPv6 where I'm taking a very pro IPv6 stance and I need someone who wants to argue the other side - effectively that most people don't need to worry about it for a long time still or until someone makes them. Any takers feel free to ping me directly... Thanks, Josh

Cisco IOS MPLS VPN Bug
by Joe Renwick 12 Mar '11

12 Mar '11

Hello All, A customer of our's has had two major outages due to a bug in Cisco's software. The network is an MPLS VPN environment. The bug has occurred on our 6500(s) with VS-S720-10G Supervisors running s72033-adventerprisek9_wan-mz.122-33.SXH6.bin. These routers are configured as BGP route-reflectors. The first time the bug hit occurred when a new route-reflector client was added. The second time was due to a topology change on the network. On both occasions the only fix was removing … [View More]the peer configurations on the RR and re-applying. Niether soft nor hard clears on the BGP neighbors worked, only the config removal. Once re-applied life was good. The bug itself was with the BGP updates sent by the RR. During the outage these updates did not include the Route Target Extended Community required by the route-reflector clients which identifies which VRF the route belongs too. Below is output on a client during the outage and after the config yanking. Notice the mysterious disappearance of the RT community. Looking to see if anyone has seen this issue particularly with this version of code. TAC is trying to tell me that this was a bug in a previous version but is fixed in the code I am running. Huh? Been running around in circles with them for a month so this is my act of desperation. Also if anyone is running a similar environment without issue I would be very interested in what version of code your using. Thanks to all who took the time to read this email...

OSPFv3 Authentication
by Manav Bhatia 12 Mar '11

12 Mar '11

Hi, I am doing a survey and was interested in knowing if network operators are using OSPFv3 with authentication [RFC 4552] turned on? I know that most providers turn on authentication with OSPFv2, but given that OSPFv3 needs IPsec integration and can thus get little cumbersome to configure, wanted to understand if a similar % of folks also turn on authentication for OSPFv3? You can unicast me your responses (if you dont wish to share it on the list) and i will collate all data and post a … [View More]
