So I've been tasked with extending a single /24 subnet across 3 data centers due to VM. We need the 3 because a witness server is required.
Data Center 1 - 2 Nexus 7710 w/vPC v8.1(1)
Data Center 2 - 1 Nexus 7706 v8.1(1)
Data Center 3 - Catalyst 9400 v16.9.3
DC 1 is connected to DC2 via 2 point-to-point 10GB links
DC 2 is connected to DC 3 via 1GB link
DC 3 is connected to DC1 via a 1GB link
I've been told that NSX is not an option.
Is this doable? What would the best design suggestion be? I've done VXLAN between 2 data centers with N7Ks before, but never 3 with a C9400
Thanks
