Configuring IP Multicast

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.

The Passport switch supports two protocols for IP multicasting:

1. Distance Vector Multicast Routing Protocol (DVMRP)

2. Internet Group Management Protocol (IGMP)

The following sections describe using Device Manager to view and modify multicast parameters:

• 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 Reference for the Passport 8000 Series Management Software Switching Operations, Release 3.1.
