MULTICAST ROUTING

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 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 3-140).

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 3-223)or PIM (page 3-232),and specify the interfaces that will participate (page 3-227or 3-233). Note that you can only enable one multicast routing protocol on any given interface.

Web – Click IP, Multicast Routing, General Setting. Set Multicast Forwarding Status to Enabled, and click Apply.

CLI – This example enables multicast routing globally for the router.

Console(config)#ip multicast-routing	4-288

Displaying the Multicast Routing Table

You can display information on each multicast route this router has learned via DVMRP or PIM. The router learns multicast routes from neighboring routers, and also advertises these routes to its neighbors. The router stores entries for all paths learned by itself or from other routers, without considering actual group membership or prune messages. The routing table therefore does not indicate that the router has processed multicast traffic from any particular source listed in the table. It uses these
