Static Route Setup
This chapter shows how to setup IP static routes.
19.1 IP Static Route Overview
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.
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 figure through remote node Router 1. However, the Prestige is
unable to route a packet to network N3 because it does not know that there is a route through
remote node Router 1 (via Router 2). The static routes allow you to tell the Prestige about the
networks beyond the remote nodes.
