Single sided vs Double Sided VPC

[CiscoBrownBelt]

So in a topology where 2x 95k Nexus will be Core, and 4x 93k Nexus will be access, is it best to join the 2x 9504 in a VPC domain let's say VPC domain 10, then 1st pair of 93k as VPC Domain11, next pair VPC domain 12.

Just do all SVI on the cores, only 1 SVI for manangement on Access switches, then configure trunks between access and core switches if you only have 1 uplink?

Double Sided vPC would be a better approach.

I didnt understand where do you have 1 uplink from?

[CiscoBrownBelt]

Access switches to Cores.

[nazimkha]

You need to have at least 2 links between two vPC domains to form a double sided vPC

[CiscoBrownBelt]

So meaning each access layer switch must have 2x links to Core 1 and 2x links to Core 2? I am confused.

Something like this

So yes that is exactly how my lab is setup.

[nazimkha · Accepted solution]

Perfect

[CiscoBrownBelt]

Should peer-switch and peer=gateway command not only be configured on the Core VPC switches but the Access VPC switches as well?
