Yea its 24.. Would even be happy to offer some champers.. I think this is more of a Maudite crowd.. Connoisseurs on here...
As I understand it you would need to write a small daemon to do the BFD state monitoring for the transmission and reception of the heartbeats with various peers. The protocol is fairly simple so for an experienced dev this should be easy. Then in OpenBGPD you would need to have a way of gracefully and forcefully immediately shutting down the BGP neighbor that matches the BFD peer. This could be achieved by simply having the BFD daemon call 'bgpctl neighbor $bfdpeer down' It is not so important for OSPF as that already has fast convergence time with fast hello's etc.. But for BGP this would make a world of difference to remove the BGP routes immediately (in less than a second) as soon as the BGP neighbor goes down/becomes unreachable (even if not a direct link (multi-hop etc)).
