+ IANA Registry for P-Multicast Service Interface (PMSI)
+ Tunnel Type Code Points
+
+Abstract
+
+ RFC 6514 created a space of Tunnel Type code points for a new BGP
+ attribute called the "P-Multicast Service Interface Tunnel (PMSI
+ Tunnel) attribute". However, the RFC did not create a corresponding
+ IANA registry.
+
+ There now is need to make further code point allocations from this
+ name space. This document serves to update RFC 6514 in that it
+ creates an IANA registry for that purpose.
+
+Status of This Memo
+
+ This is an Internet Standards Track document.
+
+ This document is a product of the Internet Engineering Task Force
+ (IETF). It represents the consensus of the IETF community. It has
+ received public review and has been approved for publication by the
+ Internet Engineering Steering Group (IESG). Further information on
+ Internet Standards is available in Section 2 of RFC 5741.

+1. Introduction
+
+ In 'BGP Encodings and Procedures for Multicast in MPLS/BGP IP VPNs'
+ [RFC6514], an optional transitive BGP attribute called the
+ "P-Multicast Service Interface Tunnel (PMSI Tunnel) attribute" is
+ specified. This BGP attribute uses an octet field to specify the
+ PMSI tunnel type. RFC 6514 allocates the values 0-7.
+
+ There is now a need to make further code point allocations from this
+ name space. In particular, "Inter-Area P2MP Segmented LSPs"
+ [SEAMLESS-MCAST] needs to make such an allocation. However, the RFC
+ did not create an IANA registry for these code points.
+
+ This document creates a new IANA registry called "P-Multicast Service
+ Interface Tunnel (PMSI Tunnel) Tunnel Types" for these code points.
+ The registry is created in the "Border Gateway Protocol (BGP)
+ Parameters" registry.
+
+ Creating this registry is an update of RFC 6514 [RFC6514].

+
+
+2. Security Considerations
+
+ This document simply creates an IANA registry from a table in RFC
+ 6514. Thus, there are no security concerns.
+
+3. IANA Considerations
+
+ IANA has created a new registry called "P-Multicast Service Interface
+ Tunnel (PMSI Tunnel) Tunnel Types" in the "Border Gateway Protocol
+ (BGP) Parameters" registry.
+
+ The allocation policy for values 0x00 to 0xFA is IETF Review
+ [RFC5226]. Values 0xFB to 0xFE are experimental and are not to be
+ assigned. 0xFF is reserved, the status of 0xFF may only be changed
+ through Standards Action [RFC5226].
+
+ The initial registry should appear as:
+
+ Value Meaning Reference
+
+ 0x00 no tunnel information present [RFC6514]
+ 0x01 RSVP-TE P2MP LSP [RFC6514]
+ 0x02 mLDP P2MP LSP [RFC6514]
+ 0x03 PIM-SSM Tree [RFC6514]
+ 0x04 PIM-SM Tree [RFC6514]
+ 0x05 BIDIR-PIM Tree [RFC6514]
+ 0x06 Ingress Replication [RFC6514]
+ 0x07 mLDP MP2MP LSP [RFC6514]
+ 0x08 - 0xFA Unassigned
+ 0xFB - 0xFE Experimental [RFC7385]
+ 0xFF Reserved [RFC7385]
