A real-world BGP TS help request

Hey gang, I'm looking for some extra eyes on a problem I'm facing. I do some side work on a modest-sized ISP network made up of 45 core routers and 54 distribution routers. Some of the core routers are set up in mated pairs, others are standalone in smaller sites. Dist routers are RR clients of their local core. Core router BGP topology is simply a full mesh (yes, it's "big" to not have a second layer of route reflectors, but with simple scripting I can mesh/unmesh a new/old core router in <10 minutes). Equipment is a mix of 7206VXR (with a mix of NPE-G1 and NPE-400) and 6504E (all Sup720-3BXL or Sup720-10G-whatever-it-is, all running either 12.2(33)SXI12 or 12.2(33)SXI13).

Everything was configured from pre-built templates. Every router has a logically-identical route map for redistributing connected routes into BGP: the loopback and the OSPF infrastructure block is ignored, then anything on a prefix-list is redistributed without 'no-export', then everything else is redistributed with 'no-export'. Same goes for static routes: a key route for real-time black holing is ignored, then a PL for export, and everything else 'no-export'. Dist routers have one peer-group: "local-core", and the local cores are in that group. Core routers have two peer groups: "local-dist" and "core-mesh", so all the cores are in one big happy update group. Dist routers do not accept "upstream" routes, to keep their routing tables simple (they can rely on an OSPF default route), and core routers do not send 'upstream' routes so there's two layers of protection. Core routers do not filter in any form (ACL, prefix list, AS ACL, route map) outbound to other core routers. The only core routers that filter inbound from other cores are the NPE-400s and any NPE-G1s with only 1/2GB RAM; they throw away upstream routes longer than a particular mask length, and rely on the default.

On one particular core router, it's got a link to Level3 for IP transit. The /30 subnet is assigned by L3, and we do EBGP over that /30 like usual. The /30 gets redistributed into BGP courtesy of the standard route map mentioned above. It's shared within the network as 'no-export', as nobody outside needs to know about it. This core router advertises that /30, about 18 routes reflected from local-dists, and another ~77k routes from Level3 to all of the other cores.

On two routers (that I've observed so far), only ~62k of those ~77k routes are being received, and the list of routes "missing" includes the /30 on the link to L3:

Any thoughts on where to look next? I'm contemplating rolling out a "next-hop-self" solution in the thought that it doesn't like the next-hop of the /30, but I'm just not on a firm base yet with that idea.

Comments

  • What are your thoughts on turning on debugging just for that /30 prefix?

    access-list 10 permit 4.59.196.28

    debug bgp ipv4 unicast updates 10

    clear ip bgp <ip of peer> soft in

    You could do clear ip bgp * soft in, but this will clear it for all peers, and it sounds like there are many! Doing shouldnt affect the data plane as its just a refresh. 

    This way you can see exactly whats going on without wasting too much time troubleshooting. Pick a single route and troubleshoot it - whatever is wrong with it will most likely be the issue with all of the other missing routes. 

    If you do decide to go down the debug path, I would strongly suggest to send it to a buffer instead of the terminal.

    Easily done. The problem was observed on a not-yet-in-production router. However, I feel like I'm not getting anything useful here:

  • hmm...that does not show the prefix coming in. 

  • Since its a non-prod box, can you enable soft-reconfiguration inbound? Perhaps you can glean some info by looking at the Adj-RIB-In.

  • peetypeety ✭✭✭ ✭✭✭

    Soft-reconfig enabled, session hard-cleared, prefix still doesn't show up, but the peer says it's sending it:

    Alpha6504#sh ip bgp neig 204.29.205.237 adv | i 4.59.196.28
    *> 4.59.196.28/30   0.0.0.0                200    400  48000 i
    Alpha6504#

    BwvlLiCore3E#sh ip bgp 4.59.196.28/30
    % Network not in table
    BwvlLiCore3E#

     

     

  • Can you send a rough diagram of the layout?

    Alpha6504 says it's advertising the route in question, along with 77k others. BwvlLiCore3E says it's not receiving the route, or another 12k of the 77k routes being sent. It is receiving 65k routes though. No BGP filtering (ACL, PL, AS ACL, RM) outbound on Alpha6504 or inbound on BwvlLiCore3E.

  • from BwvlLiCore3E:

    show ip bgp neighbors 204.29.205.211 received-routes

    Do any of the missing routes show up in this output?



  • Is it possible to lab the exact same codes in a lab environment and re-create the amount of routes I know this won't be easy but worth looking at, other then debugging other side to see where they are going it's going to be hard to deduce what's going on 

    sounds like buggy behaviour, is the hardware/ram ok on the receiving bgp peer

    seems like he's had his fair share of updates and closes the door

    from BwvlLiCore3E:

    show ip bgp neighbors 204.29.205.211 received-routes

    Do any of the missing routes show up in this output?

    Nope. At first, I was thinking "why is the question being asked, I've already covered it with the 'sh ip bgp' output", as anything received would at least show up with a (Received-only) label, but then I realized it's probably best to check every detail.

  • Is it possible that the router receives better ad/metric than bgp, causing rib-failure?

    Apologies, I'm at work so I need to gulp the texts above a bit later on.

  • peetypeety ✭✭✭ ✭✭✭

    I'm going to chalk this up to a software bug. Based on some prodding from others, I decided to see identify some of the other routes being advertised but not learned. I discovered that many (all?) of the other routes were somehow being reflected from an IBGP non-client neighbor to another IBGP non-client neighbor. Since this made no sense, I've decided to switch to a different code release that I have decent faith in, and so far it's working A-OK. Thanks all for the help and moral support!
