Abstract

Methods and network devices are disclosed relating to a multi-area communication network employing bit indexed explicit replication (BIER). In one embodiment, a method includes receiving, at a node in a communications network, a message comprising a first message bit array. The method further includes detecting a bit value of a first relative bit position in the first message bit array, where the first relative bit position represents a first group of destination nodes in the communications network, and evaluating the bit value of the first relative bit position in order to determine whether to encapsulate the received message for delivery to the first group of destination nodes. An embodiment of a network device comprises a processor adapted to implement an embodiment of the method.
