Hi Greg. We've had multiple reports now that Geneve kernel-based tunnels do not work in Open vSwitch if IPv6 is not enabled. Do you have an idea whether we should consider this a bug in OVS or a bug in the documentation? That is, should we plan to fix it (when we can) or should we plan to document that Geneve requires IPv6? (Or is something else going on?)
No rush. Thanks, Ben.
