Recommeded design with 4 units of Nexus 3172

[keofua]

Hi everyone,

I'm working on a design with 4 units of Nexus 3172, my idea is to create VPN between 2 Nexus 3172, and then create a separate VPC to cover 2 sets of 2 Nexus 3172 (it's confusing), diagram as below:-

Wondering if anyone has any similar design?

Is this design good/bad or recommeded/not recommeded?

Comments are welcome :)

Thanks,

Keo

Hello,

"my idea is to create VPN between 2 Nexus 3172", did you mean VPC and not VPN? If not please explain.

If so, I assume N3K1 & 3 is one vPC pair and N3K2 & 4 is another. That being the case, then you really can't create a vPC between vPC peer switches. Short of that, I've never created a vPC between two vPC pairs. It would probably work, but never tried it. Check this previous forum discussion, it may prove helpful:
