2025-09-11 03:30:23,285 - INFO - TEST DESCRIPTION : Test the underlay brocast traffic handling by vrouter. (Bug-1545229).
1. Send broadcast traffic from one compute node.
2. Other compute in same subnet should receive that traffic.
3. Receiving compute should treat this traffic as underlay.
4. Compute should not replicate the packet and send the copy back.
Pass criteria: Step 3-4 should pass
