Chapter 6 TCP/IP Configuration for LAN-to-LAN
6.1.2 Static Route Setup
On a directly connected internet, RIP usually handles the routing automatically. However, RIP
cannot propagate across isolated networks, as in the case before a connection is made between the
two subnetworks using one Class C IP address. Without a route, no packets can be forwarded to
their destinations. A static route is used to resolve this problem by providing your Prestige with
some static routing information. As a matter of fact, when you configure the Internet Access or a
Remote Node, a static route is implicitly created by your Prestige. An example is given below. In
the example, stations on the 204.5.1.0/24 subnetwork can access the remote stations using the
static route. The route will have a destination of 204.5.1.64/26 with the gateway address being
that of the Remote Node (204.5.1.150).
Figure 6-4. Example of Static Routing Topology
Note that in normal circumstances, your Prestige will have adequate routing information after you
configure the Internet access and Remote Nodes; you do not need to configure additional static
routes. You will need to configure static routes only for unusual cases (for example, subnetting).
