Hey Chris,

I can not say much on your case, just general "advise"/recommendations...

first:
I have not encountered a case where I needed to "tune" or explicit set
BFD settings/parameter.
Just enable BFD on the protocol, and on the BFD protocol the interfaces.
(To start with. On high latency links of course there is a need, but on
local? Keep it simple and use defaults till you encounter issues...)

second:
No need to set neighbor and local (as far as I'm aware of).
Like with the other point; just set the interface on the bfd protocol.
I don't know the specific implementations details, but source address
selection and stuff are just set "correct" and bird "is clever enough"
to sort out the rest. (which is btw a big prop to the core team that
this "just works"(tm)!!)
I.e. on protocol ospf, enable bdf and on the proto bfd set the same
interfaces. You just get bfd awareness on ospf for each neighbor. No
need to configure any neighbors.

Maybe this somehow helps you...
Bernd
