Network Working Group B. Decraene Internet-Draft Orange Updates: 4379, 6424 (if approved) N. Akiya Intended status: Standards Track C. Pignataro Expires: April 20, 2015 Cisco Systems L. Andersson S. Aldrin Huawei Technologies October 17, 2014 IANA registries for LSP ping Code Points draft-decraene-mpls-lsp-ping-registry-00 Abstract RFC 4379 and RFC 6424 created name spaces for Multiprotocol Label Switching (MPLS) Label Switched Path (LSP) Ping. However, those RFC did not create the corresponding IANA registries for DS Flags, Multipath Type, Pad TLV and Address Types. There is now a need to make further code point allocations from these name spaces. This document updates RFC 4379 and RFC 6424 in that it creates the IANA registries for that purpose.

Introduction [RFC4379] and [RFC6424] created name spaces for MPLS LSP Ping. However, those RFC did not create the corresponding IANA registries for DS Flags, Multipath Type, Pad TLV and Address Types. There is now a need to make further code point allocations from these name spaces. In particular [I-D.akiya-mpls-entropy-lsp-ping] and [I-D.akiya-mpls-lsp-ping-lag-multipath] are requesting allocation for DS Flags and Multipath Type. This document serves to update [RFC4379] and [RFC6424] in that it creates the IANA registries for that purpose. 2. IANA Considerations This document requests IANA to create new registries within [IANA-MPLS-LSP-PING] protocol to maintain "DS Flags", "Multipath Type", "Pad TLV" and "Address Types" fields. Name of registries and initial values are described in immediate sub-sections to follow. 2.1. DS Flags [RFC4379] defines the Downstream Mapping TLV, which has the Type 2 assigned from the "Multi-Protocol Label Switching (MPLS) Label Switched Paths (LSPs) Ping Parameters - TLVs" registry. [RFC6424] defines the Downstream Detailed Mapping TLV, which has the Type 20 assigned from the "Multi-Protocol Label Switching (MPLS) Label Switched Paths (LSPs) Ping Parameters - TLVs" registry. DSMAP has been deprecated by DDMAP, but both TLVs shares a field: "DS Flags". The IANA is requested to create and maintain a registry entitled "DS Flags" with the following registration procedure: Decraene, et al. Expires April 20, 2015 [Page 2] Internet-Draft IANA registries for LSP ping October 2014 Registry Name: DS flags. Bit number Name Reference ---------- ---------------------------------------- --------- 7 N: Treat as a Non-IP Packet RFC4379 6 I: Interface and Label Stack Object Request RFC4379 5-0 Unassigned Assignments of DS Flags are via Standards Action [RFC5226]. Note that "DS Flags" is a field included in two TLVs defined in "Multi-Protocol Label Switching (MPLS) Label Switched Paths (LSPs) Ping Parameters - TLVs" registry: Downstream Mapping TLV (value 2) and Downstream Detailed Mapping TLV (value 20). Modification to "DS Flags" registry will affect both TLVs. 2.2. Multipath Type The IANA is requested to create and maintain a registry entitled "Multipath Type" with the following registration procedure: Registry Name: Multipath Type. Value Meaning Reference ---------- ---------------------------------------- --------- 0 no multipath RFC4379 1 Unassigned 2 IP address RFC4379 3 Unassigned 4 IP address range RFC4379 5-7 Unassigned 8 Bit-masked IP address set RFC4379 9 Bit-masked label set RFC4379 10-250 Unassigned 251-254 Experimental This document 255 Reserved This document Assignments of Multipath Types are via Standards Action [RFC5226]. Note that "Multipath Type" is a field included in two TLVs defined in "Multi-Protocol Label Switching (MPLS) Label Switched Paths (LSPs) Ping Parameters - TLVs" registry: Downstream Mapping TLV (value 2) and Downstream Detailed Mapping TLV (value 20). Modification to "Multipath Type" registry will affect both TLVs. Decraene, et al. Expires April 20, 2015 [Page 3] Internet-Draft IANA registries for LSP ping October 2014 2.3. Pad Type The IANA is requested to create and maintain a registry entitled "Pad Type" with the following registration procedure: Registry Name: Pad Type. Value Meaning Reference ---------- ---------------------------------------- --------- 0 Reserved RFC4379 1 Drop Pad TLV from reply RFC4379 2 Copy Pad TLV to reply RFC4379 3-250 Unassigned 251-254 Experimental This document 255 Reserved This document Assignments of Pad Types are via Standards Action [RFC5226]. 2.4. Interface and Label Stack Address Type The IANA is requested to create and maintain a registry entitled "Interface and Label Stack Address Type" with the following registration procedure: Registry Name: Interface and Label Stack Address Type. Value Meaning Reference ---------- ---------------------------------------- --------- 0 Reserved RFC4379 1 IPv4 Numbered RFC4379 2 IPv4 Unnumbered RFC4379 3 IPv6 Numbered RFC4379 4 IPv6 Unnumbered RFC4379 5-250 Unassigned 251-254 Experimental This document 255 Reserved This document Assignments of Interface and Label Stack Address Types are via Standards Action [RFC5226]. 3. Security Considerations This document simply creates IANA registries for code point defined in [RFC4379] and [RFC6424]. Thus, there are no new security concerns. Decraene, et al.
