Chapter Basic Router Configuration
Configuring Dynamic Routes
DETAILED STEPS
Example
The following configuration example shows RIP version 2 enabled in IP network 10.0.0.0 and
192.168.1.0.
To see this configuration, use the show running-config command from privileged EXEC mode.
!
Router# show running-config
router rip
version 2
network 10.0.0.0
network 192.168.1.0
no auto-summary
!
Command Task
Step 1
router rip
Example:
Router> configure terminal
Router(config)# router rip
Router(config-router)#
Enters router configuration mode, and enables RIP
on the router.
Step 2
version {1 | 2}
Example:
Router(config-router)# version 2
Router(config-router)#
Specifies use of RIP version 1 or 2.
Step 3
network ip-address
Example:
Router(config-router)# network 192.168.1.1
Router(config-router)# network 10.10.7.1
Router(config-router)#
Specifies a list of networks on which RIP is to be
applied, using the address of the network of each
directly connected network.
Step 4
no auto-summary
Example:
Router(config-router)# no auto-summary
Router(config-router)#
Disables automatic summarization of subnet routes
into network-level routes. This allows subprefix
routing information to pass across classful network
boundaries.
Step 5
end
Example:
Router(config-router)# end
Router#
Exits router configuration mode, and enters
privileged EXEC mode.
