Abovenet BGP upgrade problems
On Sunday night, Abovenet upgraded their BGP sessions and ever since then I've been receiving an incomplete BGP table. They sent a nice message telling me of the upgrade(see below) but it appears that they wiped out 10,000 networks from their BGP advertisements. The networks included www.microsoft.com, nitrous.digex.net, and a /15 client network. It's been causing problems for my network and I've had a ticket open with Abovenet for over 24 hrs. They added the networks that I complained about to their advertisement, but I don't know how to get a diffs of the 10,000 networks that I'm missing. The output from my BGP summary is... 93736 network entries and 187404 paths using 15463992 bytes of memory The output from nitrous.digex.net shows... 106558 network entries and 528694 paths using 28942878 bytes of memory Are any other Abovenet customers experiencing the same problems?

Whether or not you are missing networks probably depends on your perspective: route-views.oregon-ix.net>sh ip bgp summ Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd 4.0.0.2 4 1 568948 6906 6971071 0 0 1d08h 95355 12.127.0.249 4 7018 663763 6905 6971071 0 0 1d00h 95065 134.24.127.30 4 1740 524953 6899 6971071 0 0 1d08h 95194 144.228.241.81 4 1239 651844 6901 6971071 0 0 1d08h 95395 BBN, ATT, ATT CERFnet, and Sprintlink appear to consider what you are receiving a full table. Verio considers 93,000 prefixes to be 10,000 /more/ than a full table (See Randy's post of a few days ago): 204.42.253.253 4 267 731675 6881 6971912 0 0 1d08h 83878 204.212.44.131 4 234 275728 6913 6971912 0 0 1d08h 83710 In any providers advertisements, there is going to be a certain bit of fuzz (internal networks, some deaggregates, and other things) that they advertise to transit customers but are not seen by the world. For example, downstream customers of, say, UUnet or Telia will easily see more than 100k prefixes currently, but peers will not see many of those internal routes and deaggregates. Telia is currently advertising 100-112k prefixes: route-views.oregon-ix.net>sh ip bgp summ | incl 1221 203.62.248.4 4 1221 968651 6910 6975582 0 0 1d08h 100315 203.62.252.21 4 1221 807027 6899 6975582 0 0 1d08h 112352 So, it's really a matter of perspective. If you are still having reachability problems, I'm sure AboveNet would be happy to take a look at it and fix that for you. If you're just looking for 'missing prefixes,' I'm not sure that you really are missing anything. --msa
