How to Select Static Routing on a Host That Is a Nework Client

  1. Become superuser on the host.

  2. Add an entry for a router on the network into the /etc/defaultrouter file.

(See "/etc/defaultrouter File".) A single static default route is then installed in the routing table. Under this condition, the host does not run any dynamic routing protocol (such as RIP and RDISC).
