Overview
Multicast routing and switching is the functionality of a network that allows a single host (the
multicast server) to send a packet to a group of hosts. With multicast, the server is not forced to
duplicate and send enough packets for all the hosts in a group. Instead, multicast allows the
network to duplicate the packet where needed to supply the group. Multicast greatly reduces the
bandwidth required to send data to a group of hosts. IP multicast routing is a function that allows
multicast traffic to be forwarded from one subnet to another across a routing domain.
