    Operations, Administration, and Maintenance for MPLS-SR over IP
                  draft-mirsky-mpls-oam-mpls-sr-ip-01

Abstract

   Segment routing uses source routing paradigm to traffic engineering
   by specifying segments a packet traverses through the network.  MPLS
   Segment Routing applies that paradigm to an MPLS data plane-based
   networks.  SR-MPLS over IP uses MPLS label stack as a source routing
   instruction set and uses IP encapsulation/tunneling such as MPLS-in-
   UDP as defined in RFC 7510 to realize a source routing mechanism
   across MPLS, IPv4, and IPv6 data planes.  This document describes
   Operations, Administration, and Maintenance operations in SR-MPLS
   over IP environment.

1.  Introduction

   Segment routing [RFC8402] uses source routing paradigm to traffic
   engineering by specifying segments a packet traverses through the
   network.  MPLS Segment Routing (SR-MPLS)
   [I-D.ietf-spring-segment-routing-mpls] applies that paradigm to an
   MPLS data plane-based networks.  SR-MPLS over IP uses MPLS label
   stack as a source routing instruction set and uses IP encapsulation/
   tunneling such as MPLS-in- UDP as defined in [RFC7510] to realize a
   source routing mechanism across MPLS, IPv4, and IPv6 data planes.
   This document describes Operations, Administration, and Maintenance
   (OAM) operations in SR-MPLS over IP environment.
