    abstract =  {This document defines a new SRv6 Endpoint behavior, End.B6.Encaps.Relay, for Binding SID (BSID) nodes in SRv6 networks. The behavior enables BSID nodes to relay tunnel-internal notification messages, such as ICMPv6 errors and congestion notifications, back to the upstream tunnel source node through a mapping mechanism.},
