Nokia Network Voyager Reference Guide for IPSO 6.0 - Check Point

DVMRP TunnelsA router forwards Multicast traffic to an adjacent router only if that router has a client thataccepts multicast traffic. Nokia IP security platforms require Distance Vector Multicast RoutingProtocol (DVMRP) to be enabled on the interfaces to which you forward multicast traffic.26.66/30NokiaPlatform B26.69/30NokiaPlatform C 26.73/3026.70/3026.65/30 26.74/30Nokia Platform ANokia Platform D22.1/2424.0/24DVMRP Tunnel endpoint fromISP 192.168.22.254/24 to 22.1/2422.254/24 Network Prefix: 192.168.0.0In the preceding example, a DVMRP tunnel originates from the ISP at 22.254/24. This tunnelhas a present endpoint of 22.1/24. A DVMRP tunnel set up on Nokia Platform A points to22.254/24.1. Initiate a Network Voyager session to Nokia Platform A. In this example, we use NokiaPlatform A as the starting point.1. 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: tun0c16. Enter the following in the Local IP Address text box:192.168.22.1InternetRemote PCs usingMulticast Applications7. Enter 192.168.22.254 in the Remote IP Address text box8. (Optional) Change the interfaces logical name to a more meaningful name by typing thepreferred name in the Logical name text box.00039Nokia Network Voyager Reference Guide for IPSO 6.0 51
