Hi,

Show vpc clearly states that

vPC keep-alive status : Suspended (Destination IP not reachable) that means the somehow your routing is not working.

vpc domain 100
role priority 4098
peer-keepalive destination 1.1.1.2 source 1.1.1.1

Here, by default Management VRF is chosen to route. So please check what VRF you are using in order to route the keepalive link traffic.

You can check if any firewall in between that might be blocking the default port UDP / 3200 used by the keepalive process.

peer-keepalive destination 1.1.1.1 source 1.1.1.2 vrf default

it will work
