(*, G)

A multicast routing entry used in the ASM model. * indicates any source, and G indicates a multicast group.

(*, G) applies to all multicast messages with the multicast group address as G. That is, all the multicast messages sent to G are forwarded through the downstream interface of the (*, G) entry, regardless of which multicast sources send the multicast messages.

(S, G)

A multicast routing entry used in the SSM model. S indicates a multicast source, and G indicates a multicast group.

After a multicast packet with S as the source address and G as the group address reaches a router, it is forwarded through the downstream interfaces of the (S, G) entry.

A multicast packet that contains a specified source address is expressed as an (S, G) packet.
