Network provider bridge MMRP registration snooping

摘要

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.

1. A method comprising:
creating, by a device, a multicast distribution tree that is associated with a plurality of service virtual local area networks (SVLAN)
the plurality of SVLANs being associated with one or more ports of a plurality of ports associated with the device; creating, by the device, a multicast forwarding table based on the multicast distribution tree; receiving, by the device, a data unit; extracting, by the device, a media access control (MAC) address from the data unit; determining, by the device, a particular SVLAN, of the plurality of SVLANS, associated with the MAC address; determining, by the device and based on the multicast forwarding table, the one or more ports associated with the particular SVLAN; and forwarding, by the device and via the one or more ports, the data unit.
