BFD BGP

Alexandr_P — Mon, 23 Nov 2015 21:19:00 GMT

Hi, all!

As I see in User Guide BFD can be used with static, OSPF and MPLS.
Is there road map for BFD with BGP or some workaround?

Thank you!

Hi,

maybe:

1)
- configure bgp on loopback
- advertise loopback address via ospf and configure bfd for ospf

2) configure ospf between two devices and configure bfd for ospf

Hi,

+1 for this request. Having BFD tear down a BGP session without waiting for the hold timer would be a Big Win.

Doing this via OSPF doesn't really work for BGP sessions with other networks - it would work OK (I think) for your iBGP sessions though.

BGP BFD is not available in EXOS upto 16.1.
This will be available from 21.1.

Meanwhile using loopback/OSPF on BGP connected interfaces wont work.
BGP will wait upto hold down timer expires/TCP session turn down.

We need to wait upto 21.1.
