Strangeness in the global routing tree?
This morning, I was awaken by one of my NOC guys because a customer of mine BGP was flapping. The scoop: A cisco 7206, with three full views, 128 megs of Ram, 11.1.19(CA). I have four customers off of this router on an ethernet who are running BGP to me. I am sending them full views. Two are ciscos, one is a Bay, and the other is a PC running GATED. This morning, around 8 AM, the Gated box started going crazy. The 7206 would start the BGP session, it would feed the Gated box almost all the routes, then the session would unexpectedly just die, on the cisco side it went 'idle', on the Gated side, he got an 'unexpected EOF'. So, I thought maybe he was running out of memory; so, I filtered things so he would only get about 40 routes. It worked fine. I started adding stuff (via filter-list and as-path access-lists), and worked all they way up to 50,000 routes, and it is still ok. But, if I take the filter off and feed him full routes, it breaks again. Wierd. Remember, on the same router, on the same BGP process, I am peering with two ciscos and a Bay with no problems. Any thoughts? Anyone else see the same strange behavior from a GateD box this morning? Maybe it's y2k related, or has to do with el nino... :-) -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Atheism is a non-prophet organization. I route, therefore I am.

What OS and gated version? I've been feeding "full routes" to a Linux box running gated 3.5.8, but in my case that only adds up to about 49829 routes on the Linux box. ------------------------------------------------------------------ Jon Lewis <jlewis@fdt.net> | Spammers will be winnuked or Network Administrator | drawn and quartered...whichever Florida Digital Turnpike | is more convenient. ______http://inorganic5.fdt.net/~jlewis/pgp for PGP public key____
