IP Routing Commands 971
ip route
Use the ip route command in Global Configuration mode to configure a
static route. Use the no form of the command to delete the static route. The
IP route command sets a value for the route preference. Among routes to the
same destination, the route with the lowest preference value is the route
entered into the forwarding database. Specifying the preference of a static
route controls whether a static route is more or less preferred than routes from
dynamic routing protocols. The preference also controls whether a static
route is more or less preferred than other static routes to the same
destination.
