Abstract
Various systems and methods are disclosed for performing multicast routing over unidirectional links. For example, one method involves maintaining a multicast adjacency state, which is associated with an interface that is coupled to receive messages from a network device via a unidirectional link. The multicast adjacency state identifies a network address of the network device. The method also involves sending a multicast protocol control message to the network device via a bidirectional path. The destination address of the network multicast protocol control message is the network address in the multicast adjacency state.
