I currently have a production WAAS environment leveraging WCCPv2 for redirection with a single WAAS at each of my 3 data centers. I want to add a second WAAS into the WCCP for each location. Can somebody please provide a link for configuring this? I have seen you can do multi-cast or unicast wccp groups. Is that correct? Is there a benefit to one over the other. Thanks for your help.
