This document provides a configuration example for route health injection (RHI) on a Cisco Content
Switching Module (CSM).

RHI allows the CSM to advertise the availability of a virtual IP (VIP) address throughout the network.
Multiple CSM devices with identical VIP addresses and services can exist throughout the network. One CSM
can override the server load−balancing (SLB) services over the other devices if the services are no longer
available on the other devices. One CSM also can provide the services because it is logically closer to the
client systems than other SLB devices. The CSM advertises the VIP address as a host route.

There are no specific requirements for this document.

The information in this document is based on the CSM running version 3.x or 4.x.

The information in this document was created from the devices in a specific lab environment. All of the
devices used in this document started with a cleared (default) configuration. If your network is live, make sure
that you understand the potential impact of any command.
