Hi everyone,
Having some issues with load balancing two webservers using two CSS11501 content service switches (VIP/interface redundancy, Active/Backup, and Active Session Redundancy setup).
I've set up both CSSs to load balance the web servers behind it, and it works with Active/Backup setup. When I configure it with Active Session Redundancy though for stateful failover, I start to have issues. For example, as a test, I'm downloading a file through the load balancers from the web server. Mid-download, when I do a reboot on the master CSS, the download just suddenly stops (meaning, my ASR stateful config didn't work.. duhh). the funny thing is this: after the CSS finishes rebooting, and both are up again, I can't access the web servers through vip address at all (times out on my web browser). To get it up and running again, I would first need to unplug the ethernet cables from the master CSs, wait awhile, then re-attach.
I've tried many variations on fixing this issue, but have been unsuccessful. Any help is appreciated. I've attached the running config on both CSSs for your reference (i've chnaged the IPs around, of course, but you get the idea):
