Which architecture does not require an explicit multicast signaling protocol, such as PIM or P2MP, to signal the multicast state hop-by-hop, but instead uses a link state protocol to advertise the…

Binary indexed explicit routing is not a defined networking architecture or standard; it is a fabricated distractor.

Binary intermediate enhanced routing is not a defined networking architecture or standard; it is a fabricated distractor.

Bit Indexed Explicit Replication (BIER) uses IS-IS or OSPF extensions to advertise BIER forwarding information across the network, so each router knows how to forward multicast packets based on the bit string in the header. This design eliminates the need for PIM or P2MP RSVP-TE to signal multicast state hop-by-hop, as the link state protocol handles state distribution. The bit string in each packet identifies the exact set of egress nodes that need to receive the packet.
