Detailed Description

Generic multicast route in an IRoutingTable.

Multicast datagrams are forwarded along the edges of a multicast tree. The tree might depend on the multicast group and the source (origin) of the multicast datagram.

The forwarding algorithm chooses the route according the to origin (source address) and multicast group (destination address) of the received datagram. The route might specify a prefix of the origin and a multicast group to be matched.

Then the forwarding algorithm copies the datagrams arrived on the parent (upstream) interface to the child interfaces (downstream). If there are no downstream routers on a child interface (i.e. it is a leaf in the multicast routing tree), then the datagram is forwarded only if there are listeners of the multicast group on that link (TRPB routing).
