Bit Indexed Explicit Replication (RFC 8279). En router som supporterar BIER kallas Bit-Forwarding Router (BFR).

Några fördelar med BIER:

  • No Reverse Path Forwarding (RPF) checks
  • No Rendezvous Points
  • No shared tree -> source tree switchover
  • No receiver driven tree building
  • State is in the packet and not in the network.
