OVS 2.9 I'm transferring to use OVN, but for those nodes which have external network connection, they may face this problem, except to configure Jumbo frames, is there any other workaround? I am not clear on the situation however. You mention about configuring jumbo frames which means you can avoid the fragments by doing this ? No, I can't guarantee that, only can do it inside OpenStack, it is limited. If this is true, then this is the best way to proceed since performance will be better. What is wrong with jumbo frames ? It's good but it's limited can't be guaranteed, so I am asking is there any other way without IP fragmentation so far. It sounds like you want to avoid IP fragmentation; so far so good. I am not sure I understand the whole picture though. Maybe you can describe what you see ?; maybe a simple diagram would help ? BR. Hui.
