                 draft-raza-bess-srv6-services-yang-00

Abstract

   This document defines a YANG data model that can be used to configure
   and manage SRv6 based services in BGP.

   The YANG module in this document conforms to the Network Management
   Datastore Architecture (NMDA).

1.  Introduction

   YANG [RFC6020] [RFC7950] is a data definition language that was
   introduced to define the contents of a conceptual data store that
   allows network devices to be managed using NETCONF [RFC6241].

   Segment Routing (SR), as defined in [RFC8402], is source routing
   paradigm where a node steers a packet through an ordered list of
   instructions, called segments.  A segment is idenfied using its SID
   (Segment Identifier) and may represent a topological path, a service
   endpoint, a virtual network function, etc.  The IPv6 dataplane
   instantiation of SR is called SRv6 as specified in
   [I-D.ietf-spring-srv6-network-programming]

   BGP overlay service endpoints can be identified using SRv6 service
   SIDs.  These services include L3VPN, EVPN, and Internet services.
   The procedures and messages for BGP overlay services using SRv6 SID
   are specified in [I-D.dawra-bess-srv6-services]

   This document defines the YANG model for managing these SRv6 based
   services in BGP.
