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]. + + + + + +Andersson & Swallow Standards Track [Page 2] + +RFC 7385 PMSI IANA registry October 2014 + + +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] + + + Figure 1 + +4.
