YANG Data Model for OSPFv3 Segment Routing

This document defines a YANG module for OSPFv3 extensions for Segment Routing . It is an augmentation of the OSPF SR base YANG model, where the configuration for both OSPFv2 and OSPFv3 are defined. and are not referenced in the document text but within the YANG module itself.
