The BGP Control Plane for the SR service-chaining solution is consistent with the BGP Control Plane for the topological Segment Routing Traffic Engineering (SR-TE) solution. o BGP Link-State(BGP-LS) address-family/sub-address-family[RFC7752] is used to discover service and topological characteristics from the network. o SR-TE policies[I-D.ietf-idr-segment-routing-te-policy] instantiate source-routed policies that may mix service and topological segments.
