Chapter 1 Basic Router Configuration

Configuring Static Routes

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. Configuring static routes on the Cisco Secure Router 520 Series router is optional.

Perform these steps to configure static routes, beginning in global configuration mode:

	Command		Purpose
Step 1
	ip route prefix mask {ip-address interface-type		Specifies the static route for the IP packets.
	interface-number [ip-address]}		For details about this command and additional
	Example:		parameters that can be set, see the Cisco IOS IP
			Command Reference, Volume 2 of 4: Routing
	Router(config)# ip route 192.168.0.0		Protocols.
	255.255.0.0	10.10.10.2
	Router(config)#
Step 2
	end		Exits router configuration mode, and enters
			privileged EXEC mode.
	Example:
	Router(config)# end
	Router#

For complete information on the static routing commands, see the Cisco IOS Release 12.3 documentation set. For more general information on static routing, see Appendix B, “Concepts.”

Configuration 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 Fast 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 commands marked “(default).” These commands appear automatically in the configuration file generated when you use the show running-configcommand.

Verifying Your Configuration

	To verify that you have properly configured static routing, enter the show ip route command and look
	for static routes signified by the “S.”
	You should see verification output similar to the following example.
	Router# show ip route
	Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
	D - EIGRP, EX - EIGRP external,
	i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
