I imagine the bridge ports are being flooded looking for the final destination.

Hi,

I am using vpp v18.01-rc0~160-ge13c799 (show version in vppctl). I feel I find a bug.

I have two physical interfaces TenGigabitEthernet5/0/0 (int1) and TenGigabitEthernet5/0/1 (int2).

Normally, if I send traffic (from another server) to int1, I expect int2 should NOT receive the traffic. This is true when int2 is in l3 mode.

However, if I set int2 to l2 mode (e.g., set interface l2 bridge TenGigabitEthernet5/0/1 2), int2 will receive the same traffic as int1 does. This problem happens no matter int1 is in l2 or l3 mode. I use the trace to confirm that int2 receives the same traffic as int1 does.

Does anyone know this problem?

Thanks,
