Administering | A multicast tunnel allows multicast packets to cross several unicast routers |
Multicast Tunnels | 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. |
Displaying | To display the IP multicast tunnels on the router: |
