This wizard is intended for leaf routers, which are at the edge of the network. The wizard will not create a multicast network. An additional rendezvous point candidate and mapping agent must exist. Refer to the Auto-RP documentation in Configuring IP Multicast Routing for more information.

Follow these steps to enable multicast routing on one or more Catalyst 3550 multilayer switches in the cluster:

  1. Select a Catalyst 3550 multilayer switch from the Current Candidates list.
    Click Select All below the list if you want to enable all switches in the list.
  2. Click Add to move your selections to the Enable Multicast list.
    To remove a switch from the Enable Multicast list, select the switch and click Remove. To remove all the switches, click Select All and Remove.

The PIM mode for routable interfaces on the enabled switches is set to Sparse-Dense. Multicast forwarding is enabled for each switch. The state of the CGMP server on the switches is not changed.
