[c-nsp] ibgp convergence time ?

[julien leroiso]

Hi,

I have 2 bgp routers (named border1 and border2) with a ebgp session to one
ISP (yyy.yyy.yyy.yyy) and ibgp session (xxx.xxx.xxx.1 and xxx.xxx.xxx.2).

My border2 is very very slow to converge. After +-3h I didn't get all my
border1 routes.
I reset the session it's the same. I tryed to debug but I found nothing
interresting.

Is it normal that ibgp is slower to converge than ebgp ?
