Would it be feasible to go the EVPN over MPLS route? Arista might support
some basic MPLS forwarding (most Data-Centre switches do).

Never understood this VXLAN nonsense in DC universe (not the comics), in SP
space this was a solved problem and is a well-trodden path since ever -PWs,
VPLS now EVPN (even with traffic engineering possibilities -you know the
mice around elephant flows...)
MPLS to DCs is my answer.
