E. Rosen: AUTHOR [+2]
A BGP attribute, "P-Multicast Service Interface (PMSI) Tunnel" attribute is defined in [RFC6514]. This attribute, referred to as the "PMSI Tunnel" attribute in this document, contains a one-octet "Flags" field. Only one flag is defined in that RFC, but there is now a need to define additional flags. However, that RFC did not create an IANA registry for the assignment of bits in the "Flags" field. This document creates a registry for that purpose. In addition, there may be a need to define more than eight flags. Therefore this document defines a new BGP Extended Community, "Additional PMSI Tunnel Attribute Flags", that can be used to carry additional flags for the "PMSI Tunnel" attribute. A registry is also created for this Extended Community, allowing IANA to assign flag bits from the Extended Community's six-octet value field.

Registry and Extensions for P-Multicast Service Interface Tunnel Attribute Flags
The BGP-based control procedures for Multicast Virtual Private Networks (MVPNs) 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 "P-Multicast Service Interface (PMSI) Tunnel" attribute. This document updates RFC 6514.
