Configuring broadcast, unknown unicast, and multicast forwarding

All switches in a Brocade VCS Fabric cluster share a single multicast tree rooted at the RBridge with the lowest RBridge ID (domain ID). All broadcast, unknown unicast, and multicast traffic between two edge RBridges is forwarded on this multicast tree inside the Brocade VCS Fabric. The multicast tree includes all RBridges in the Brocade VCS Fabric.
