[rbridge] Consensus Check: Hellos

[Eastlake III Donald-LDE008]

This is the last of the consensus checks via the mailing list to confirm
or refute an apparent
consensus at the Philadelphia meeting.


******* The VLANs on which an Rbridge sends TRILL IS-IS Hellos is
expanded to include those for which it is an appointed forwarder except
to the extent that it is configured not to send these additional Hellos.


If no particular controversy arises over this in the next two weeks, we
will declare it to be the working group consensus.

Thanks,
Donald & Erik

PS: There was not complete agreement on this although there did appear
to be a rough consensus at the meeting. However, in light of the other
consensus from that meeting to no longer require the "decapsulation
check" (see
http://www.postel.org/pipermail/rbridge/2008-April/002939.html) and the
discussions of the trade-offs, perhaps the consensus should be that, by
default, Rbridges MUST either (1) send these additional Hellos if they
are an appointed forwarder or (2) perform the decapsulation check.
