Configures

A static route for a network

Default

None

Description

This command defines a static route to the destination network specified by its network address and mask. next-hop-address is the IP address of the router to which traffic for this destination network should be sent. distance is an optional administrative distance that allows you change the way the static route behaves. If the distance is high enough, it can be overwritten by dynamic protocols. See Chapter 8 for more information about administrative distances. The permanent keyword tells the router to keep the route in the route table even if the interface goes down. The router normally removes static routes that are invalid because the interface is down.

Example

The following commands create two static routes. The first route sends traffic for the 192.168.1.0/24 network to 10.1.1.1; the second route sends traffic for the 192.168.2.0/24 network to 10.2.2.2.

ip route 192.168.1.0 255.255.255.0 10.1.1.1
ip route 192.168.2.0 255.255.255.0 10.2.2.2
