Configuring Static Routes

Static routes provide fixed routing paths through the network. They are manually configured on the

router. If the network topology changes, the static route must be updated with a new route. Static routes

are private routes unless they are redistributed by a routing protocol.

To configure static routes, follow these steps, beginning in global configuration mode.

SUMMARY STEPS

1. ip route prefix mask {ip-address | interface-type interface-number [ip-address]}

2. end

DETAILED STEPS

Example

In the following configuration example, the static route sends out all IP packets with a destination IP

address of 192.168.1.0 and a subnet mask of 255.255.255.0 on the Gigabit Ethernet interface to another

device with an IP address of 10.10.10.2. Specifically, the packets are sent to the configured PVC.

You do not need to enter the command marked “(default).” This command appears automatically in the

configuration file generated when you use the show running-config command.

ip classless (default)

ip route 192.168.1.0 255.255.255.0 10.10.10.2!

Command Purpose

Step 1

ip route prefix mask {ip-address | interface-type

interface-number [ip-address]}

Example:

Router(config)# ip route 192.168.1.0

255.255.0.0 10.10.10.2

Router(config)#

Specifies the static route for the IP packets.

For details about this command and about

additional parameters that can be set, see Cisco

IOS IP Command Reference, Volume 2 of 4:

Routing Protocols, Release 12.3

Step 2

end

Example:

Router(config)# end

Router#

Exits router configuration mode, and enters

privileged EXEC mode.
