[rbak-nsp] BGP - GracefulRestart & BFD - how does it work ?

[Marcin Kuczera]

hello,

I have a customer who has a customer that is very sensitive to BGP 
failovers.
I mean - holdtime is a problem if there is a real fault between routers 
(not just bgpd restart).

There is quite long timeout - restart 120s + 90s of holdtime..

Ok, we don't have problems everyday - but recently before upgrade to 
12.1.1.2 we did for a week.
So I need to find some soft solution for future cases.

Now, I'am wondering what will happen if we start using BFD between our 
and our customer routers.
Is the BDF for BGP a separate process from bgpd ?

I mean - I would like to keep graceful restart for bgpd crash cases, and 
BFD for linecard crashes case.
Does anyone has an experience using these features together and could 
share its opinion ?

(and drop a example of BFD config for a BGP peer ;)

Regards,
Marcin
