Use the Multicast Tunnels View to manage multicast tunnels and DVMRP operations on an GIGAswitch/IP or IP Switch Gateway.
To present the Multicast Tunnels View, click the Multicast Tunnels link in the Config Tool main menu.
If there are currently no multicast tunnels, this view presents only a field in which to enter the IP address of a new tunnel. The following figure shows an example.

If tunnels have been created, a list of existing tunnels is presented. The following figure shows an example of this view.

The following section describes the fields in the Multicast Tunnels View. Note that a value for the Local Address field is mandatory. You can use the default values for all other parameters; they are reasonable for a large number of environments.
