ABSTRACT:
Methods and systems for distributing multicast messages in a network are disclosed. The use of such a method or system in an Ethernet network can result in a reduction in the number of flooded multicast messages. One method can involve receiving a companion message, which includes a multicast address, at a network device and extracting the multicast address from the companion message. The multicast address can then be associated with a VLAN and an interface of the network device. Another method involves receiving a join message, which identifies a multicast group being joined, and generating a companion message corresponding to the join message. The companion message includes an address of the multicast group.
