YANG Data Model for Segment Routing
draft-ietf-spring-sr-yang-29
Abstract
This document defines a YANG data model for segment routing
configuration and operation, which is to be augmented by different
segment routing data planes. The document also defines a YANG model
that is intended to be used on network elements to configure or
operate segment routing MPLS data plane, as well as some generic
containers to be reused by IGP protocol modules to support segment
routing.
