Hello:
According to [1], OVN is honouring the DF bit. From the testing report:
"""
All works as expected according the following guidelines:
DF=0 --> the device will learn the real MTU and after first pkt, the traffic flows
DF=1 --> the router discard the traffic but the sender does not perform fragmentation so traffic does not flow
"""
Having said that, that test is done in the opposite direction: from the VM to an external network with smaller MTU. But that should work in both directions, N/S and E/W traffic.
Can you trace the packets and the DF flag reaching the router GW port?
Regards.
