bgp convergence time

[taozeng]

Is anyone know how to tune the bgp convergence time? We have application which require less than 10 seconds convergence time. But so far we found the bgp convergence took almost 10-12 seconds. We tune the bgp keep alive/dead interval and advertise interval so far. Are there any other methods to make it faster?

Thanks a lot.

A few things:

1. Globally Resilient IP

(http://www.cisco.com/univercd/cc/td/doc/solution/ip_sol/grip/grip_ovr.htm

Never worked with it but claims to improve covergence by 40%.

2. Create peer groups

3. timers

Hope it helps.
