Network Working Group B. Decraene Internet-Draft Orange Updates: 4379, 6424 (if approved) N. Akiya Intended status: Standards Track C. Pignataro Expires: September 7, 2015 Cisco Systems L. Andersson S. Aldrin Huawei Technologies March 6, 2015 IANA registries for LSP ping Code Points draft-ietf-mpls-lsp-ping-registry-03 Abstract RFC 4379 and RFC 6424 created name spaces for Multiprotocol Label Switching (MPLS) Label Switched Path (LSP) Ping. However, those RFCs did not create the corresponding IANA registries for the Downstream Mapping object Flags (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 RFCs 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.ietf-mpls-entropy-lsp-ping] and [I-D.ietf-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. Note that "DS Flags" and "Multipath Type" are fields 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 their registry will affect both TLVs. 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 (DSMAP) 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 (DDMAP) TLV, which has the Type 20 assigned from the "Multi-Protocol Label Switching (MPLS) Label Switched Paths (LSPs) Ping Parameters - TLVs" registry. Decraene, et al. Expires September 7, 2015 [Page 2] Internet-Draft IANA registries for LSP ping March 2015 DSMAP has been deprecated by DDMAP, but both TLVs share a field: "DS Flags". The IANA is requested to create and maintain a registry entitled "DS Flags" with the following registration procedure: 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]. 2.2. Multipath Type The IANA is requested to create and maintain a registry entitled "Multipath Type". The registration policies [RFC5226] for this registry are: 0-250 Standards Action 251-254 Experimental Use 255 Standards Action IANA is requested to make the following initial assignments: 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 Decraene, et al. Expires September 7, 2015 [Page 3] Internet-Draft IANA registries for LSP ping March 2015 2.3. Pad Type The IANA is requested to create and maintain a registry entitled "Pad Type". The registration policies [RFC5226] for this registry are: 0-250 Standards Action 251-254 Experimental Use 255 Standards Action IANA is requested to make the following initial assignments: Registry Name: Pad Type. Value Meaning Reference ---------- ---------------------------------------- --------- 0 Reserved This document 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 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". The registration policies [RFC5226] for this registry are: 0-250 Standards Action 251-254 Experimental Use 255 Standards Action IANA is requested to make the following initial assignments: Decraene, et al. Expires September 7, 2015 [Page 4] Internet-Draft IANA registries for LSP ping March 2015 Registry Name: Interface and Label Stack Address Type. Value Meaning Reference ---------- ---------------------------------------- --------- 0 Reserved This document 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 3. Security Considerations This document simply creates IANA registries for code point defined in [RFC4379] and [RFC6424]. Thus, there are no new security concerns. 4. References 4.1.
