Re: BGP AFI or SAFI for advertising BFD status

Uuuuuu that's sounds great!
Exactly what I was wondering.

Create a VRF called BFD-RouteServer on each PE, on that VRF on each PE
activate the IPs of Route-Server, and activate de BFD Sessions with the
participants connected to that PE.
And then, add a PBR deviation of BFD coming from participants to that
Route-Server IP replicas.

Having that weird Anycast of BFD deployed, now comes the part of making
Route-Servers being aware of the status of those Distributed BFD Sessions.

Does any colleague have any clue about BFD session status propagation over
BGP?


this internet draft discusses the problem space

Unfortunately there are no known implementations of the protocol.
