Chapter 9 Device Network Settings The following table describes the labels in this screen. Table 121 Device Operation > Device Configuration > Network > Routing > Static Route > Add LABEL DESCRIPTION Destination IP This parameter specifies the IP network address of the final destination. Routing is always based on network number. If you need to specify a route to a single host, use a subnet mask of 255.255.255.255 in the subnet mask field to force the network number to be identical to the host ID. Subnet Mask Enter the IP subnet mask here. Gateway IP Select the radio button and enter the IP address of the next-hop gateway. The gateway is a router or switch on the same segment as your ZyWALL's interface(s). The gateway helps forward packets to their destinations. Interface Select the radio button and a predefined interface through which the traffic is sent. Metric Metric represents the "cost" of transmission for routing purposes. IP routing uses hop count as the measurement of cost, with a minimum of 1 for directly connected networks. Enter a number that approximates the cost for this link. The number need not be precise, but it must be 0~127. In practice, 2 or 3 is usually a good number. Apply Click Apply to save your changes back to the ZyWALL. Cancel Click Cancel to exit this screen without saving. 9.12 The RIP Screen RIP (Routing Information Protocol, RFC 1058 and RFC 1389) allows a device to exchange routing information with other routers. Use the RIP screen to specify the authentication method and maintain the policies for redistribution. First, the Authentication field specifies how to verify that the routing information that is received is the same routing information that is sent. Second, the ZyWALL can also redistribute routing information from non-RIP networks, specifically OSPF networks and static routes, to the RIP network. Costs might be calculated differently, however, so you use the Metric field to specify the cost in RIP terms. 308 Vantage CNM User's Guide
