Summary: Almost ready for publication as a standards track RFC

Major issue:
The security considerations section is essentially empty (what it currently
says reduces to "don't let malformed packets crash your implementation". Surely
there's more to say here. Is there an assumption that, in any given deployment,
the administrators of the bier layer and the ospf layer are the same people,
and have the same authority? If so, it's probably worth saying so. If not, are
there edges to discuss? If this document really doesn't introduce any new
security considerations, it should argue why that's the case.

Minor issues:
Is there a reason not to use the example/documentation IPV4 address ranges?
(See the shepherd writeup). The author count is above the current
RFC-Editor/IESG recommendations. Work that out with your ADs.
