I have an advance question about vPC design below. Basically I have two data centers connected as back to back vPC, and I have a requirement of connecting the below pair switches across the four aggregation switches.
Do you think a scenario like this will have a spanning tree loop, by blocking the other legs toward the HSRP listening devices? Or still, it will be working as A/A as vPC eliminate the spanning-tree behavior.
What is the best connectivity for the pair switches to achieve the residence across 4 switches?
