Bit Index Explicit Replication (BIER) [RFC8279] is an architecture that provides multicast forwarding through a "BIER domain" without requiring intermediate routers to maintain multicast related per-flow state. BIER can be supported in MPLS and non-MPLS networks. The common BIER header format and encapsulation for MPLS and non-MPLS networks is specified in [RFC8296]. BIER in Ethernet encapsulation is an example of BIER encapsulation in non-MPLS networks. [RFC8401] specifies the required extensions to the IS-IS [RFC1195] protocol for the distribution of BIER sub-domain information including the Sub-sub-TLV required to support BIER in MPLS encapsulation for MPLS networks. This document specifies the required extensions to the IS-IS [RFC1195] protocol for supporting BIER in non-MPLS networks using BIER in Ethernet encapsulation.
