Hi Acee,
What I meant is that BFD always augments the control palne protocols in
ietf-routing model. And the BFD augmentation can be used as-is or mounted in
LNE or in NI.

Reshad.

Hi Reshad,
Are you saying that BFD would never augment the list of control place
protocols in ietf-routing and always be at the root of the tree (whether it be
the device, LNE, or NI)? I guess it doesn't have to be in the list since it
will never install routes in the routing table.
Thanks,
Acee

Ietf-bfd augments the ietf-routing model, that's not conditional. How
the ietf-bfd model is used may vary:
1) It may be used "directly" in a device (i.e no schema mount)
2) It may be schema mounted for use in an LNE
3) It may be schema mounted for use in a VRF
I thought this was the case for all routing protocols.

Reshad.

I thought about that after I replied. I guess you are saying that
it is conceivable for a network device to support ietf-bfd but not support
routing (ietf-routing)?
Thanks,

Right, schema-mount can be used in some cases (logical device
or in a VRF) but doesn’t have to be used in other cases (e.g. network device
which doesn't support VRFs). We will clarify the text, at a certain time we
incorrectly thought that schema mount had to be used in all cases.
Regards,
Reshad.

This is what I thought but the text is kind of misleading:
BFD can operate in the following contexts:
[...]
The approach taken is to do a schema-mount (see Schema
Mount
[I-D.ietf-netmod-schema-mount]) of the BFD model in the
appropriate
locations.
