Network Working Group L. Andersson Internet-Draft Huawei Technologies Updates: 6514 (if approved) G. Swallow Intended status: Standards Track Cisco Systems Expires: February 13, 2015 August 12, 2014 IANA registry for PMSI Tunnel Type code points draft-ietf-l3vpn-pmsi-registry-05 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 an IANA registry for these. 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.

Introduction In RFC 6514 '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 now is need to make further code point allocations from this name space. In particular, draft-ietf-mpls-seamless-mcast [I-D.ietf-mpls-seamless-mcast] needs to make such an allocation. However the RFC did not create an IANA registry for these codepoints. 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. Code points in RFC 6514 RFC 6514 allocated the values 0 to 7 as follows: + 0 - No tunnel information present + 1 - RSVP-TE P2MP LSP + 2 - mLDP P2MP LSP + 3 - PIM-SSM Tree + 4 - PIM-SM Tree + 5 - BIDIR-PIM Tree + 6 - Ingress Replication Andersson & Swallow Expires February 13, 2015 [Page 2] Internet-Draft PMSI IANA registry August 2014 + 7 - mLDP MP2MP LSP 3. Security Considerations This document simply creates an IANA registry from a table in RFC 6514. Thus, there are no security concerns. 4. IANA Considerations IANA is requested to create 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. Values 0xFB to 0xFE are experimental and are not to be assigned. 0xFF is reserved. The initial registry should appear as: Value Meaning Reference 0x00 no tunnel information present [RFC 6514] [RFC-to-be] 0x01 RSVP-TE P2MP LSP [RFC 6514] [RFC-to-be] 0x02 mLDP P2MP LSP [RFC 6514] [RFC-to-be] 0x03 PIM-SSM Tree [RFC 6514] [RFC-to-be] 0x04 PIM-SM Tree [RFC 6514] [RFC-to-be] 0x05 BIDIR-PIM Tree [RFC 6514] [RFC-to-be] 0x06 Ingress Replication [RFC 6514] [RFC-to-be] 0x07 mLDP MP2MP LSP [RFC 6514] [RFC-to-be] 0x08 - 0xFA Unassigned 0xFB - 0xFE Experimental [RFC-to-be] 0xFF Reserved [RFC-to-be] Figure 1 5.
