Hi, The packet has a multicast destination MAC so it was flooded, including to the BVI. The BVI dropped it because it does not have a valid ether type. The trace says the ethertype value was 0x162. I don’t know what a gns3 simulation is, nor do I want to 😉

Could gns3 simulation conditions cause it?

I see in trace that the ARP packet after l2 flooding goes to the Non-BVI output interface , but this doesn't happen for a loopback/BVI interface. thus I can't ping 100.3.4.4 from 100.3.4.11. create bridge-domain 2 set int l2 bridge GigabitEthernet2/6/0 2 set int state GigabitEthernet2/6/0 up create loopback interface set int l2 bridge loop0 2 bvi set int state loop0 up set int ip address loop0 100.3.4.12 / 3.3.3.3/24<http://3.3.3.3/24> Should I configure a route for loop0/BVI or use set ip arp command? I also use ip route table 0 100.3.4.0/24<http://100.3.4.0/24> via loop0 but the problem remains.I use vpp 18.10.
