The MLX platform is not a layer2 switch by default, so there are two ways to solve this problem:
a) Use a VLL-local to bridge VLAN 999 from the firewall, through the MLX, to the ICX2. Then the MLX does not even learn the MAC addresses of the packets which are passing through. b) Perform a "no route-only" on all the interfaces which are involved in layer2 switching.
