     Internet-Draft                 SRv6 OAM                       July 2017 
         

     Abstract 

        This document outlines various use-cases for Operations, 
        Administration, and Maintenance (OAM) in Segment Routing with the 
        IPv6 data plane (SRv6) network. It also describes how the existing 
        OAM mechanisms can be used to address SRv6 OAM requirements.
