ULTICAST OUTING
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 LANplex router.
When you define the tunnel, you specify the associated index on the local
LANplex router and then the characteristics of the tunnel. Tunnel
characteristics are the same as the 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 tunnel(s) on the router, from the top level menu
of the Administration Console, enter:
ip multicast tunnel display
