Abstract
A provider edge bridge in a service provider network receives multiple media access control (MAC) Registration Protocol (MMRP) registration messages from customer networks via tunnels. The provider edge bridge snoops the MMRP registration messages to obtain multicast MAC addresses from the registration messages, and tunnels the MMRP registration messages toward one or more other bridges. The provider edge bridge constructs multicast forwarding tables based on the multicast addresses obtained from snooping the MMRP registrations, and uses the multicast forwarding tables for forwarding data units from the provider edge bridge towards destinations.
