Troubleshooting
On Cisco routers with Internet Operating System (IOS) version 12.3T, the PBR support for Multiple Tracking Options feature allows the router to check if a machine is still functioning. This feature can detect if the HP EFS WAN Accelerator is up and, if not, to stop redirecting the traffic to it.
You can use the following methods to check an HP EFS WAN Accelerator:
Internet Control Message Protocol (ICMP) ping reach-ability to a remote device.
Application running on a remote device (for example, the device responds to an HTTP GET request).
A route exists in the Routing Information Base (RIB) (for example, policy route only if 10.2.2.0/24 is in the RIB).
Interface state (for example, packets received on E0 should be the policy routed out of E1 only if E2 is down).
