Registry and Extensions for P-Multicast Service Interface Tunnel Attribute Flags
RFC 7902, “Registry and Extensions for P-Multicast Service Interface Tunnel Attribute Flags”, is a Proposed Standard document published in June 2016 by E. Rosen, T. Morin. It updates RFC 6514. The canonical text is published by the RFC Editor.
Abstract
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.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
