vPC in a VDC scenerio

[Arjun Dabol]

Hi,

We have 2 n7K that need to be in vPC pair.
We are also going to have 2 diff VDC on these N7K

-----N7K-1------                 ------N7k-2-----
vdc-A      vdc-B                  vdc-A      vdc-B

So now if ee have to create vPC between these 2 N7K , do we need different vPC peer links between these N7Ks.
Is it like  2 peer links between both vdc-A and  2 peer link between both vdc-B .

thanks

Thnx manish. My question was more related to design -

So in general, if I have  create vPC pair between 2 switches and they are running 2 Different VDCs - how that should be done ?

Hi Arjun,

As per the Nexux7K NX-OS Interface config guide

A vPC domain is associated to a single VDC, so all vPC interfaces belonging to a given vPC domain must be defined in the same VDC. You must have a separate vPC peer link and peer-keepalive link infrastructure for each VDC deployed. Consolidating a vPC pair (two vPC peer devices of the same domain) in two VDCs of the same physical device is not supported.
