RELATED IDEAS

z/VM should support reflective_relay and cisco ACI

This capability would solve real-world networking issues for zVM. The current OSA implementation has no way to associate mac addresses with vlan tags, so we can't use cisco ACI + bridge domains to segment traffic into multiple vlans on a single subnet.

This would at least allow us to turn on VEPA on the vswitch and force the traffic to the physical switch so ACI can handle it. For us, this is applicable to z16 and beyond.

Furthermore, VEPA should be supported on global vswitches.
