Chapter 1 Basic Router Configuration
Configuring Static Routes
Configuration Example
The following configuration shows the command-line access commands.
You do not need to input the commands marked “default.” These commands appear automatically in the
configuration file generated when you use the show running-config command.
!
line con 0
exec-timeout 10 0
password 4youreyesonly
login
transport input none (default)
stopbits 1 (default)
line vty 0 4
password secret
login
!
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
1800 series routers is optional.
Perform these steps to configure static routes, beginning in global configuration mode:
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.”
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 additional
parameters that can be set, see the
Cisco IOS IP
Command Reference, Volume 2 of 4: Routing
Protocols.
Step 2
end
Example:
Router(config)# end
Router#
Exits router configuration mode, and enters
privileged EXEC mode.
