Static Route
This chapter tells you how to configure static routes for the Prestige.
8.1.1

Basics

If you wish to know more about static route basics , please read on. Skip to the Static Route Setup section for the
actual configuration.
Static routes tell a router 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 a router 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 the same remote node Router 1 (via gateway Router 2). The static routes are for
you to tell the Prestige about the networks beyond the remote nodes.

8.1.2

Static Route Setup

Static routes are required if the DSL client has more than one public IP address. The routing information (static
route) entered in the secondary machine will be passed to the primary machine through RIP. By adding static
routes, the Prestige knows how to route packets belonging to the public IP addresses back to the DSL client's local
network. The Prestige supports up to 240 static routes. Enter "p" to view a precious page of static routes and "n" to
