Hi,

I support the trill-p2mp-bfd draft.

1)      Does the support of multi-point BFD aid deployments?

Yes, it should be good for monitoring multi-destination connectivity.

2)      Are the suggested additions to RFC7177 bootstrapping
sufficient for this technology?

I believe the changed part of RFC 7177 relates to one-hop sessions
only. There can certainly be one-hop sessions between a head and
multiple tails since, for example,  the link can be a broadcast link
consisting of a bridge LAN with multiple RBridges attached. I do not
think the bootstrap mechanism in RFC 7177 or this modified version is
sufficient for multi-hop sessions since it uses Hellos rather than
LSPs. Multi-hop sessions are presumably configured by the network
manager.

3)      Do you feel this technology is ready for standardization?

Yes.

Thanks,
Donald
