ip route

This command configures a static route. The ipaddr parameter is a valid IP address, and subnetmask is a valid subnet mask. The nexthopip parameter is a valid IP address of the next hop router. Specifying Null0 as nexthop parameter adds a static reject route. The optional preference parameter is an integer (value from 1 to 255) that allows you to specify the preference value (sometimes called “administrative distance”) of an individual static route. Among routes to the same destination, the route with the lowest preference value is the route entered into the forwarding database. By specifying the preference of a static route, you control 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. A route with a preference of 255 cannot be used to forward traffic.

The description parameter allows a description of the route to be entered.

For the static routes to be visible, you must perform the following steps:

• Enable ip routing globally.
• Enable ip routing for the interface.
• Confirm that the associated link is also up.
