Overview

IP multicasting provides services such as the delivery of information to multiple destinations with a single transmission and the solicitation of servers by clients. These services benefit applications such as video conferencing, dissemination of datagram information, and dissemination of mail or news to a large number of recipients.

A Passport 8600 module supports two protocols for IP multicasting:

• Internet Group Management Protocol (IGMP) is used by hosts to report their multicast group memberships to neighbor multicast routers.
• Distance Vector Multicast Routing Protocol (DVMRP) is used between routers to exchange multicast routing information.

• Configuring IGMP for the router interface
• Configuring and viewing DVMRP
• Viewing IP Multicast protocol interface information

For procedures for setting IGMP snooping, refer to the information about working with VLANs in Configuring Switching Operations for the Passport 8000 Series Switch Using Device Manager Release 5.1.x.
