I am looking for some suggestions...Here is the scenario:
I have two DCs and each has a pair N7K running sa vPC as the core. I have a ACI multi-site for the same two DCs. Now I am planning to move the existing networks and workloads into ACI in order to remove the N7Ks from DC network... Simple diagram is attached for reference. Some of the existing networks are L2 stretched between two DCs.
If there were just a single N7K vPC, there should not be any issue of building this kinda back-to-back vPC migration path/topology to move networks and workloads. However, I am having concern about with two pairs of N7Ks are inter-connected besides the multi-site ISN for ACI...especially worried about spanning-tree considering ACI does not parcipate in STP and would put some unexpected interruptions or blocks on interfaces...
So any suggestions for this use case scenario?
