Subject: [rbridge] Working Group Last Call: draft-ietf-trill-rbridge-protocol-13.txt

From: Donald Eastlake <[email-masked]>

The changes between the -12 and -13 versions of the base protocol
draft were sufficiently extensive that we have decided that another
Working Group Last Call is required. This message starts a two week
WGLC which ends July 15th.

Thanks,
Donald and Erik
