'rtr responder' instead of 'ip sla monitor' ?

I have written some code for a Cisco 6509. I want to check traffic on all LAN and WAN VLANs to see if it is destined to, or arriving from, a particular Data Centre. If it is, then I want that traffic redirected to a particular device. I first want to check that the device is alive; if it is not alive, then I want the traffic to ignore the code and traverse the network as per usual. I wrote the below code only to find out that the version of software (12.2) on the 6509 does not support the ‘ip sla monitor’ command. I have been advised that I should use the ‘rtr responder’ command instead. Can someone tell me what code I would need to run to replace the below code that I had already written? I’m a little short on time and don’t have time to spend days researching; I was hoping someone in here might have the knowledge?
