Hugo, I think those are all valid potential reasons to use BFD. I use it
for some of the same reasons even on direct connect peers.
Only time I ever recall actively avoiding it if I had the capability was if
I had NSF/SSO, since they didn't used to (still don't?) play very well
together.
On Tue,
Hugo,
I've used this configuration in a past line when I may of had multiple L2
steps between L3 devices. The only concern we had was around load BFD put
on _some_ endpoint routers, if was handles on the RouteProcessor vs on line
cards.

Good morning, nanog,
Is there any/sufficient benefit in adding BFD onto BGP sessions between
directly-connected routers? If we have intermediate L2 devices such that
we can't reliably detect link failures BFD can help us quickly detect peers
going away even when link remains up, but what about
