Hi all: I have performed an Operations Directorate review of draft-ietf-bess-pta-flags-02 "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.
