Cisco's Implementation of IP Multicast Routing

Cisco IOS software supports the following protocols to implement IP multicast routing:
• Internet Group Management Protocol (IGMP) is used among hosts on a LAN and the routers (and
• Protocol-Independent Multicast (PIM) protocol is used among routers and multilayer switches to track
• Distance Vector Multicast Routing Protocol (DVMRP) is used on the multicast backbone of the Internet
• Cisco Group Management Protocol (CGMP) is used on Cisco routers and multilayer switches connected
