Hi all:

I have performed an Operations Directorate review of

  "The BGP-based control procedures for Multicast Virtual Private
   Networks make use of a BGP attribute known as the "P-Multicast
   Service Interface (PMSI) Tunnel" attribute.  The attribute contains a
   one-octet "Flags" field.  The purpose of this document is to
   establish an IANA registry for the assignment of the bits in this
   field.  Since the Flags field contains only eight bits, this document
   also defines a new BGP Extended Community, "Additional PMSI Tunnel
   Attribute Flags", that can be used to carry additional flags for the
   PMSI Tunnel attribute.  This document updates RFC 6514."

This is a short draft that does exactly what its abstract (above) says.

The reason for asking IANA to create two new registries are explained -
it seems that this is because providers now want to support Multicast
Virtual Private Networks by using PMSI Tunnels in BGP; that makes it
clear that the new registries are needed.

The draft spells out exactly how the PMSI Tunnel Flags and its (new)
Extended Community Additional FLags should be handled by BGP - that's
spelt out clearly, so - as far as I can see - it should not cause
any operational problems.

Overall, the draft is clear, simple and easy to understand.
I believe it is ready for publication as an RFC.

Cheers, Nevil
