Nexus to L2 6500s

Hoping I can get some clarification on a design. I have a typical pair of 6500s doing L2 only, vPCed upstream to Peered 7Ks where the SVIs are running HSRP. Rapid STP root and HSRP actives are on the primary role switch 1. In the attached drawing, do I have the STP alternate port states correct?

Nexus to L2 6500s

Hello Ben,

Your almost there however the segment connecting the 6500's together, one would assume the Designated Role (having presented the Superior BPDU on the segment) and the other would assume the role of Alternate.

A similar topology to your attachment is depicted on pg.57 of "Design and Configuration Guide: Best Practices for Virtual Port Channels (vPC) on Cisco Nexus 7000 Series Switches."
