IP Multicast Wizard

This wizard appears when you choose Device > IP Multicast Wizard on the menu bar.

The 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 switch from the Current Candidates list. Only Catalyst 3550 multilayer switches are listed.
    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.
  3. Click OK.

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.

To enable a disabled CGMP server, choose Device > IP Multicast Routing and use the IP Multicast Routing window.
