(Forgot to CC c-nsp) Someone is advertising a block with insane long prepend. We added it to our filter list and it seems most providers have filtered out that route by now.
Our 28xx decided to flip out with IBGP. IOS 12.4(21). Is this a bug? Is there a bugID on this or a workaround to filter insane route? Can I filter prefix by how big it is? It's this route. #sh ip bgp 94.125.216.0 BGP routing table entry for 94.125.216.0/21, version 92436 Paths: (2 available, best #1, table Default-IP-Routing-Table) Flag: 0x820 Not advertised to any peer x.x.x.x from y.y.y.y (z.z.z.z) Origin IGP, metric 10, localpref 100, valid, external, best Community: 13697912 13697913 209 1299 29113 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 47868 4 On Mon, Feb 16, 2009 at 11:55 AM, Ozar <vegasnet...@gmail.com> wrote: > I am starting to see random BGP neighbor messages from multiple neighbors > on > different boxes. > > %BGP-3-NOTIFICATION: received from neighbor X.X.X.X 3/11 (invalid or > corrupt > AS path) 516 bytes > > I dont see much documentation on this, and we are in the process of opening > a TAC case, just curious if anyone else has seen these and may be able to > shed some light. > > > Thanks > _______________________________________________ > cisco-nsp mailing list cisco-nsp@puck.nether.net > https://puck.nether.net/mailman/listinfo/cisco-nsp > archive at http://puck.nether.net/pipermail/cisco-nsp/ > _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
