Introduction to Routing
... To do multicast routing, each router computes a spanning tree covering all other routers in the subnet. When a process sends a multicast packet to a group, the first router examines its spanning tree ad prunes it, removing all lines that do not lead to hosts that are members of the group. The simple ...
