Thanks very much. Can Open VSwitch GRE tunnel support ipv6 ? Since we have the private ip address conflicting problem when tunneling different clusters. Each cluster has its dedicated DHCP server assigning ip addresses. It is possible to assign the same ip for VM at two cluster. When they are isolated, that is fine. But when those two cloud hosts are tunneled. that would be a problem.
Is there any solution solving the ip conflicting problem on open Switch ? There are multiple VMs with private ip (for example., 192.168.0.2) address at each host. Any consideration on this concern in Open vSwitch ?
