From the top level of the Administration Console, enter:

ip multicast tunnel define

Enter the index number(s) of the interface(s) with which you want to associate a multicast tunnel.

Enter the IP address of the destination multicast router.

The IP address of the destination multicast router must be a remote address. The destination router cannot be directly connected to the same subnetworks as the local IP address.

4Enter the DVMRP metric value of the tunnel.

5Enter the Time To Live (TTL) threshold of the tunnel.

6Enter the rate limit of the tunnel.

Example:

Enter an IP interface index [1]: 2

Enter remote IP address: 192.9.200.40

Enter tunnel DVMRP metric [1]: 1 Enter tunnel TTL threshold [1]: Enter tunnel rate limit [0]:

To remove an IP multicast tunnel:

From the top level of the Administration Console, enter:

ip multicast tunnel remove

Enter the index number(s) of the interfaces associated with the tunnel you want to remove.

Example:

Enter an IP interface index [1]: 2

The tunnel is removed.
