Hello All, I would like to learn more about OVN and especially the maximum MTU that I can use in my environment. Current Setup 4.3.10 Network was created via UI -> MTU Custom -> 8976 -> Create on External Provider -> Connect to Physical Network So my physical connection is MTU 9000 and I have read that Geneve uses 24 bits (maybe that's wrong ?) , thus I have reduced the MTU to 8976. I did some testing on the VMs and ping with payload of '8914' was the maximum I could pass without fragmenting and thus the MTU on the VMs was set to 8942. Did I correctly configure the test network's MTU and am I understanding it correctly that we need extra 34 bits inside the network for encapsulation ? I have checkedĀ https://www.ovirt.org/develop/release-management/features/network/managed_mt... but I don't see any refference how to calculate the max MTU. Best Regards, Strahil Nikolov
