1. With peer-switch turned on, do I give same priority on non-vPC vlans like the vPC ones, or do I give lower value on the primary and higher on the secondary?
2. I will have a separate port-channel to carry non-vPC vlans. Can I use one vlan for L3 routing peering between the two Nexus?
I Strongly suggest look at the Desing guide.
If you have still question, we would like to know how is your network and where you placing this nexus switches ? do you have exiting network with spanning tree.
vPC designed meant to mitigate the spanning tree in DC Environment.
