                   OSPFv3 CodePoint for MPLS LSP Ping
             draft-nainar-mpls-lsp-ping-ospfv3-codepoint-00

Abstract

   IANA has created "Protocol in the Segment IS Sub-TLV" registry and
   "Protocol in the Label Stack Sub-TLV of the Downstream Detailed
   Mapping TLV" under the "Multi-Protocol Label Switching (MPLS) Label
   Switched Paths (LSPs) Ping Parameters" registry.  RFC8287 defines the
   code point for different Interior Gateway Protocol (IGP).

   This document proposes the code point to be used in the Segment ID
   Sub-TLV and Downstream Detailed Mapping TLV when the IGP protocol is
   OSPFv3.

1.  Introduction

   IANA has created "Protocol in the Segment IS Sub-TLV" registry and
   "Protocol in the Label Stack Sub-TLV of the Downstream Detailed
   Mapping TLV" under the "Multi-Protocol Label Switching (MPLS) Label
   Switched Paths (LSPs) Ping Parameters" registry [IANA-MPLS-LSP-PING].
   [RFC8287] defines the code point for different Interior Gateway
   Protocol (IGP).

   [RFC5340] describes OSPF version 3 (OSPFv3) protocol to support IPv6.
   [RFC5838] describes the mechanism to support multiple address
   families (AFs) in OSPFv3.  Accordingly OSPFv3 may be used to
   advertise IPv6 and IPv4 prefixes.

   This document proposes the code point to be used in the Segment ID
   Sub-TLV (Type 34, 35 and 36) and Downstream Detailed Mapping (DDMAP)
   TLV when the IGP protocol is OSPFv3.

2.  Terminology

   This document uses the terminologies defined in [RFC8402], [RFC8029],
   [RFC8287] and so the readers are expected to be familiar with the
   same.
