This really depends on the network architecture and assumes that you
can remap the VNIs in the entire network. You might want to run L3
with group definitions across multiple L2 VNI segments. A second issue
is that many hardware VXLAN VTEPs do VNI based learning and will run
into capacity limits.

I'm not saying it's impossible but it's very tricky to intergrate if
you can't start from scratch. The whole point of this is to come up
with something that is painfully easy to use and integrate without
requiring to change much.
