DVMRP TunnelsDVMRP TunnelsDVMRP (Distance Vector Multicast Routing Protocol) tunnels encapsulate multicast packets IPunicast packets. This technique allows two multicast routers to exchange multicast packets evenwhen they are separated by routers that cannot forward multicast packets.For each DVMRP tunnel you create, you must provide the IP address of the interface that formsthe local endpoint of the tunnel and the IP address of the multicast router that is at the remote endof the tunnel forming the remote endpoint of the tunnel.NoteThe remote multicast router must support IP-in-IP encapsulation and must be configuredwith a tunnel interface to the local router.When you have created the DVMRP tunnel interface, set all other DVMRP multicastconfiguration parameters from the DVMRP configuration page.To create a DVMRP tunnel1. Click Interfaces under Configuration > Interface Configuration in the tree view.2. Click Tunnels in the Physical column.3. From the pulldown menu in the Create a new tunnel interface with encapsulation, selectDVMRP.4. Click Apply.Each time you select a tunnel encapsulation and click Apply, a new tunnel appears in thetable.5. Click the logical interface name in the Interface column of the Logical interfaces table; thistakes you to the interface page for the specified tunnel. Example: tun0c1.6. Enter the IP address of the local end of the DVMRP tunnel in the Local address text box.The local address must be one of the systems interface IP addresses and must also be theremote address configured on the DVMRP tunnel on the remote router.7. Enter the IP address of the remote end of the DVMRP tunnel in the Remote Address textbox.The remote address must be the IP address of the multicast router at the remote end of theDVMRP tunnel. It cannot be one of the system’s interface addresses.8. (Optional) Change the interface’s logical name to a more meaningful name by typing thepreferred name in the Logical name text box.Click Apply.9. (Optional) Add a comment to further define the logical interfaces function in the Commentstext box.Click Apply.10.
