    abstract =  {This document defines a YANG data model ({[}RFC6020{]}, {[}RFC7950{]}) for segment routing ({[}RFC8402{]}) configuration and operation. This YANG model is intended to be used on network elements to configure or operate segment routing MPLS data plane {[}RFC8660{]}. This document defines also generic containers that SHOULD be reused by IGP protocol modules to support segment routing.},
