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.
Status of This Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.

1. 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.

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.
