[c-nsp] Long list of route-maps

[Paul Stewart]

Why a route-map PER peer?  Can you not group them under the same conditions
and simplify things a bit?

This may not be the problem .... sounds like something else possibly..

Subject: [c-nsp] Long list of route-maps

I feel desperate: I just turned up a new Transit Session with an
upstream and my router goes nuts and is dropping other BGP sessions on
it: 4/0 (hold time expired) 0 bytes

The situation is like this:

The router is peering on a public IX with approximatively 150 members.
Each BGP session has its own route-map, so the list is really BIG!

When I turned up my transit about an hour ago, CPU went to 100% and is
still at 100% right now and it drops BGP peers and brings them back,
and drops and brings them back, ... I'm in a loop and I think the only
way to get out of that look is to bring up each bgp peer step by step
- really not an option.

CPU utilization for five seconds: 100%/5%; one minute: 99%; five minutes:
99%

What is eating my router's CPU?
Is it the big list of route-maps?
