IANA Registries for LSP Ping Code Points

and created name spaces for MPLS LSP Ping. However, those RFCs did not create the corresponding IANA registries for DS Flags, Multipath Types, Pad TLVs, and Interface and Label Stack Address Types. There is now a need to make further code point allocations from these name spaces. In particular, and request new DS Flags and Multipath Type allocations. This document updates and in that it creates IANA registries for that purpose. Note that "DS Flags" and "Multipath Type" are fields included in two TLVs defined in the "Multi-Protocol Label Switching (MPLS) Label Switched Paths (LSPs) Ping Parameters - TLVs" registry: Downstream Mapping (DEPRECATED) (value 2) and Downstream Detailed Mapping (value 20). Modification to either registry will affect both TLVs.

Per this document, IANA has created new registries within the "Multi-Protocol Label Switching (MPLS) Label Switched Paths (LSPs) Ping Parameters" registry to maintain DS Flags, Multipath Types, Pad TLVs, and Interface and Label Stack Address Types fields. The registry names and initial values are described in the immediate subsections that follow.

defines the Downstream Mapping (DSMAP) TLV, which has Type 2 assigned from the "Multi-Protocol Label Switching (MPLS) Label Switched Paths (LSPs) Ping Parameters - TLVs" registry. defines the Downstream Detailed Mapping (DDMAP) TLV, which has 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 share a field: DS Flags. IANA has created and now maintains a registry entitled "DS Flags". The registration policy for this registry is Standards Action . IANA has made the following initial assignments:

IANA has created and now maintains a registry entitled "Multipath Types". The registration policies for this registry are as follows:

IANA has made the following initial assignments:

IANA has created and now maintain a registry entitled "Pad Types". The registration policies for this registry are:

IANA has made the following initial assignments:

IANA has created and now maintains a registry entitled "Interface and Label Stack Address Types". The registration policies for this registry are:

This document simply creates IANA registries for code points defined in and . Thus, there are no new security concerns.
