/etc/defaultrouter File

This file should contain an entry for each router that is directly connected to the network. The entry should be the name for the network interface that functions as a router between networks.

In Figure 4–1, the network interface le1 connects machine timbuktu with network 192.9.201. This interface has the unique name timbuktu-201. Thus, the machines on network 192.9.200 that are configured in local files mode have the name timbuktu-201 as the entry in /etc/defaultrouter.
