What steps do I need to take to prepare to start running HSRP between two 4006's. One running Sup III and one running Sup IV. I also want to collapse 3 networks onto the switches. The current switch IP is 10.1.1.108 and I want to use Intervlan routing to place networks 10.99.1.xxx, 10.98.1.xxx and 10.97.1.xxx onto the switching environment and off of my 7200 to free up three ehternet ports on the router.
