A method for processing multicast data packets has steps for (a) requesting a second router upstream router by a multiple-processor data router to join a multicast group, the request including identification of a single physical ingress port from a plurality of available ports for receiving the multicast data packets; (b) preparing a multicast forwarding information base (MFIB) limited to only forwarding information incorporating the identified physical ingress port, and distributing the MFIB to a client software module hosting the identified physical ingress port; (c) receiving the multicast data packets at the identified ingress port; and (d) using only the MFIB to route the received multicast data packets.

Method and apparatus for distributing routing instructions over multiple interfaces of a data router

A software application in a multi-processor data router in which a forwarding information base for the router is maintained is provided with a server module and one or more client modules, each client module associated with one or more communication interfaces of the data router. The application is characterized in that the server module sends to each client module only that portion of the forwarding information base specific to the communication interfaces associated with the client module.
