While the conventional setup is that the bridge alone would get the IP and not igb1, I think being able to observe the packets in question on igb1= is still important for debugging purposes. There's also an incorrect looking comment in if_bridge.c that I'll dig into= a little later; in bridge_forward(), we claim that tapping multicast/broadcast traffic isn't important because it will be reinjected into ether_input. I c= an't see how this is true. AFAICT these packets will travel bridge_broadcast() -> bridge_enqueue() -> if_transmit OR just bridge_enqueue() -> if_transmit, wh= ich will typically not involve ether_input. --=20 You are receiving this mail because: You are the assignee for the bug.=
