VPC ISSUE

Hello..... please help!

I am having an issue with VPC, which I believe is set up correctly! Please see the attached diagram with config.    I have also pasted all the configs that are relevant below.. I hope.

Basically, communication between server 0 and servers 1 and 2 is fine when both SVI's are up, however, shutting down one SVI of VLAN 40 will result in Server 0 only being able to ping one of the servers - server 1 for example. Bringing that SVI up and downing another will result in the other server (server 2) being reachable and server 1 not being reachable.

It is also worth noting that the server's active nic's are facing different sides of the aggregation layer, so there is clearly a layer 2 issue but I just cant see where it is.

Can anyone suggest what it may be based on the configs attached? I'm happy to put any further config if required. Below are the SVI configs from each core.

If anyone can suggest anything it would be greatly appreciated.

Thank you
