I see no reason why this shouldn't work. We had separate P routers due to our physical topology, but this would have worked with only PEs. Not that the Sup720s need to support MPLS, so you require at least the 3B iirc. How many 6500s and VRFs are you talking about using? Also note, with the

Spanning tree is automatically enabled on the Cisco switches- you don't need to configure anything. Alternatively, you can use a port-channel but you would need to configure that. HP Procurve switches come with spanning tree disabled. On Mon, Mar 25, 2013 at 6:12 PM, M K gunner_...@live.com
