While responding to Martin Thomson's GRASP review, I had another
look at the ACP draft.
What it says about multicast during ACP creation is fine.
However, I'm still not finding a clear statement that the ACP,
viewed as a VRF instance, will correctly forward GRASP link local
multicasts to all other nodes on the same physical link.
In other words, when the ACP is up and running, and a normal
GRASP instance sends a multicast to port 7017 at ALL_GRASP_NEIGHBORS
(ff02::xxxx) on its interface to the ACP VRF, how is that propagated?
And when the GRASP instance binds to GRASP_LISTEN_PORT and
performs IPV6_JOIN_GROUP to ALL_GRASP_NEIGHBORS whose messages
will it receive?
