Abstract:
Bit Index Explicit Replication (BIER) is an architecture that
provides multicast forwarding through a "BIER domain" without
requiring intermediate routers to maintain multicast related per-flow
state. Neither does BIER require an explicit tree-building protocol
for its operation. A multicast data packet enters a BIER domain at a
"Bit-Forwarding Ingress Router" (BFIR), and leaves the BIER domain at
one or more "Bit-Forwarding Egress Routers" (BFERs). The BFIR router
adds a BIER header to the packet. Such header contains a bit-string
in which each bit represents exactly one BFER to forward the packet
to. The set of BFERs to which the multicast packet needs to be
forwarded is expressed by the according set of bits switched on in
BIER packet header.
This document describes the OSPF protocol extension required for BIER
with MPLS encapsulation.
