Chapter 42 Configuring IP Unicast Routing
Configuring RIP
If you want to configure an interface running RIP to advertise a summarized local IP address pool on a
network access server for dial-up clients, use the ip summary-address rip interface configuration
command.
Note If split horizon is enabled, neither autosummary nor interface IP summary addresses are advertised.
Beginning in privileged EXEC mode, follow these steps to
set an interface to advertise a summarized
local IP address and to disable split horizon on the interface:
To disable IP summarization, use the no ip summ
ary-address rip router configuration command.
In this example, the major net is
10.0.0.0. The summary address 10.2.0.0 overrides the autosummary
address of 10.0.0.0 so that 10.2.0.0 is advertised out interface Gigabit Ethernet port 2, and 10.0.0.0 is
not advertised. In the example, if the interface is still in Layer 2 mode (the default), you must enter a no
switchport interface configuration command before entering the ip address interface configuration
command.
Note If split horizon is enabled, neither autosummary nor interface summary addresses (those configured with
the ip summary-address rip router configuration command) are advertised.

Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface interface-id Enter interface configuration mode, and specify the Layer 3
interface to configure.
Step 3
ip address ip-address subnet-mask Configure the IP address and IP subnet.
Step 4
ip summary-address rip ip address ip-network mask Configure the IP address to be summarized and the IP
network mask.
Step 5
no ip split horizon Disable split horizon on the interface.
Step 6
end Return to privileged EXEC mode.
Step 7
show ip interface interface-id Verify your entries.
Step 8
copy running-config startup-config (Optional) Save your entries in the configuration file.
