Re: [Idr] Fwd: New Version Notification for draft-spaghetti-idr-bgp-sendholdtimer-05.txt

Hi Job,

In my books we should really discourage people from using BGP keepalives
and move them over to BFD protocol to determine liveness of BGP sessions.

While this draft perhaps does improve RFC4271 I am not sure if we are
moving in the right direction.

The draft does not even mention BFD once which is disappointing.

Kind regards,
Robert
