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.
For the static routes to be visible, you must perform the following steps:
• Enable ip r
outing globally
.
• Enable ip routing f
or the interface.
• Confirm that the associated link is also up.
