I have a network of 6500 series switches with SUP720s for my backbone and I want to separate the traffic for some of the users. The links between the core devices are routed with ip addresses on each side not trunked using vlans for routing. I can't bring down the routed links or add additional links between the 6500s, but I need to set up vrf on the core.
I was thinking I could set up gre tunnel with ip vrf forwarding in the setup and route across the existing links. Will the links have to be put into the vrf or can I tunnel across them? Hope this makes sense. Any one had to do this? Any other suggestions?
