Updates: 6514 (if approved) February 11, 2015
Intended status: Standards Track
Expires: August 15, 2015
IANA Registry for P-Multicast Service Interface Tunnel Attribute Flags
draft-rosen-bess-pta-flags-00.txt
Abstract
RFC6514 defines the "P-Multicast Service Interface Tunnel (PMSI
Tunnel) attribute". This attribute contains an octet of "flags".
Only one flag is defined in that RFC, but there is now a need to
define additional flags. Since the RFC did not create a registry for
the assignment of flag bits, this document updates the RFC by
creating a registry for that purpose.

1. Introduction
[RFC6514] defines the "P-Multicast Service Interface Tunnel (PMSI
Tunnel) attribute". This attribute contains an octet of "flags".
Only one flag is defined in that RFC, but there is now a need to
define additional flags. Since the RFC did not create a registry for
the assignment of flag bits, this document creates a registry for
that purpose.
2. IANA Considerations
IANA is requested to create a new registry called "P-Multicast
Service Interface Tunnel (PMSI Tunnel) Attribute Flags" in the
"Border Gateway Protocol (BGP) Parameters" registry.
Per [RFC6514] section 5, a PMSI Tunnel Attribute contains a "Flags"
octet. The Flags field is a single octet, with bits numbered, left-
to-right, from 0 to 7. IANA is requested to initialize the registry
as follows:
