Prestige 480 Dual BRI ISDN Router
5-6 Remote Node TCP/IP Configuration
5.2.1 Static Route Setup
Static routes tell the Prestige routing information that it cannot learn automatically through other means. This
can arise in cases where RIP is disabled on the LAN or a remote network is beyond the one that is directly
connected to a remote node.
Figure 5-6 Example of Static Routing Topology
Each remote node specifies only the network to which the gateway is directly connected, and the Prestige has
no knowledge of the networks beyond. For instance, the Prestige knows about network N2 in the following
diagram through remote node Router 1. However, the Prestige is unable to route a packet to network N3
because it doesn’t know that there is a route through remote node Router 1 (via gateway Router 2). Static
routes are for you to tell the Prestige about networks beyond the remote nodes.
