We do this to connect N7k's @ datacenter1 to VSS @ datacenter2 to transport
SAN traffic. Works quite well in fact. Not sure of your exact topology in
regards to layer 3, but check out the link below from Brad in regards to
the vPC peer-link and routing. As long as you don't have to route via the
peer-link, you should be good with the solution Pete describes.
