Multilayer vPC with N9K and N3K

[rootswitch]

Hello,

According to official Cisco vPC documentation one use case is:

Inside Data Center:
◦ Single-sided vPC (access layer or aggregation layer)
◦ Double-sided vPC, also called multilayer vPC (access layer using vPC interconnected to aggregation layer
using vPC)

Is it possible to have aggregation layer with a pair of N9K in a vCP domain and some of the access pairs to be each a vPC domain? Any document/link that clearly prevents to do so or states that is instead possible?

Best Regards.

The document does not mention 9k nd 3k models. But it mentions close to Figure 9 Nexus 7k and 5k. I was looking for a generic statement that Nexus models/releases can be mixed provided that a single domain includes the same model.
