As implementer and author I think this is ready for publication,
except for one minor issue. I'm not aware of any IPR.
In section 7 it says:
IGMPv1-v3, MLDv1-v2: These protocols [RFC4604] do not require any
changes for LISP-Multicast for two reasons. One is that they are
link-local and not used over site boundaries, and the second is
that they advertise group addresses that don't need translation.
RFC 4604 is about IGMPv3, MLDv2 and SSM. Hence the reference should be
updated. I'm not sure if there is a single common reference for all of
them.
Thanks,
Stig
