Hi, I am trying to configuring openstack with one controller and one network and two compute nodes. I am not able to understand how the communication of the VM's happens which are for the same tenant with same ip range but on the different compute hosts. Please help me to understand how GRE communication happens. Regards, Arumon -------------- next part -------------- An HTML attachment was scrubbed...
