The Inter-network East West traffic is not workingm after a compute node is unstacked and restacked. The static Arp and L3 forwarding rules for inter-network east west traffic were not programmed after a unstack/restack for the compute node. This was the reason for failure.

Sample static Arp and L3 forwarding flows:
