Example:
Select IP stack by slot (2,3,7,9-12|all) [12]:
Enter an IP interface index [1]: 2
Enter Interface DVMRP metric [1]: 1
Enter Interface TTL threshold [1]:
Enter interface rate limit in KBits/sec [0]:
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.
Not all multicast configurations require a tunnel. The only configurations
that require a tunnel are those that require a connection between two
multicast internetworks through one or more unicast routers.
To display the IP multicast tunnels on the router:
1 From the top level menu of the Administration Console, enter:
ip multicast tunnel display
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]:
