Administering
Multicast Tunnels
A multicast tunnel allows multicast packets to cross several unicast routers
to a destination router that supports multicast routing. A tunnel has two
end points. The local end point is associated with an interface on the
Layer 3 Module.
When you define the tunnel, specify the associated interface on the
Layer 3 Module 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.
You only need to define a multicast tunnel if you need to set up a
connection between two multicast internetworks through one or more
unicast routers.
Displaying Multicast
