Chapter 29 Configuring IP Unicast Routing
Configuring RIP
Note In general, Cisco does not recommend disabling split horizon unless you are certain that your application
requires it to properly advertise routes.
Beginning in privileged EXEC mode, follow these steps to disable split horizon on the interface:
To enable the split horizon mechanism, use the ip split-horizon interface configuration command.
Configuring Summary Addresses
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 summary-address rip router configuration command.
