3 Configuring the Switch

Multicast Routing

This router can route multicast traffic to different subnetworks using either Distance Vector Multicast Routing Protocol (DVMRP) or Protocol-Independent Multicasting - Dense Mode (PIM-DM). These protocols flood multicast traffic downstream, and calculate the shortest-path, source-rooted delivery tree between each source and destination host group. They also rely on messages sent from IGMP-enabled Layer 2 switches and hosts to determine when hosts want to join or leave multicast groups.

DVMRP builds a source-rooted multicast delivery tree that allows it to prevent looping and determine the shortest path to the source of the multicast traffic. PIM also builds a source-rooted multicast delivery tree for each multicast source, but uses information from the router’s unicast routing table instead of maintaining its own multicast routing table, making it routing protocol independent. Also note that the Dense Mode version of PIM is supported on this router because it is suitable for densely populated multicast groups which occur primarily in the LAN environment.

If DVMRP and PIM-DM are are not enabled on this router or another multicast routing protocol is used on your network, you can manually configure the switch ports attached to a multicast router (page 3-174).

Configuring Global Settings for Multicast Routing

To use multicast routing on this router, you must first globally enable multicast routing as described in this section, globally enable DVRMP (page 3-264)or PIM (page 3-271),and specify the interfaces that will participate (page 3-267or 3-272). Note that you can only enable one multicast routing protocol on any given interface.
