A multicast tunnel allows multicast packets to cross several unicast routers 
to a destination router that supports multicast. A tunnel has two end points. 
The local end point is associated with an interface on the CoreBuilder router. 

When you define the tunnel, you specify the associated index on the local 
CoreBuilder router and then the characteristics of the tunnel. Tunnel 
characteristics are the same as those of an interface. You also specify the IP 
address of the remote multicast router.

To display the IP multicast tunnels on the router: 

1 From the top level menu of the Administration Console, enter:

2 Enter the slot of the switching module for which you want to display a 

multicast interface.

Select IP stack(s) by slot (2,3,7,9-12|all) [9]:
