Prestige 153/153X WAN Bridge/Routers
5-6 Remote Node TCP/IP Configuration
5.1.2 IP 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.
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 R. 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 R.
The static routes are for you to tell the Prestige about the networks beyond the remote nodes.
