Comment 9 for bug 1889454

Hello,

I'm actually working on this bug.

In fact, it may cause a serious problem when it comes to receiving paquet with size larger than mtu, OVS bridge will drop, the log that you are seing is a serious problem, it means that you are receiving paquet larger than your bridge mtu and OVS drop it !!!!

You can test that on IXIA or with iperf.

This problem isn't reproduced on Linux bridge because, like you have already said, it has no local port.
Virtuel port with type internal for ovs bridge is the main cause of this problem.

So what I'm actually working on, is to drop packet with size larger than mtu only for ports who there type is different than internal.
Actually that's the normal behave because bridge should behave as a switch in this case.

I will keep you up-to-date.
