Thanks Robert for the quick response

Just thinking out loud -  I can see there maybe some advantages of
elimination of L2 to the host but the one major disadvantage is that BGP
multipath provides flow based uneven load balancing so not as desirable
from that standpoint compare to L3 MLAG bundle XOR Src/Dest/Port hash.

Other big down side is most enterprises have the hypervisor managed by
server admins but if you run BGP now that ends up shifting to network.
More complicated.

Kind regards

Gyan
