Multiple networks with network_type of 'vlan' are already allowed to have the same segmentation ID with the ml2, openvswitch, or linuxbridge plugins - the networks just need to have different physical_network names. If they have the same network_type, physical_network, and segmentation_id, they are the same network. What else would distinguish them from each other? Could your use case be addressed by simply using different physical_network names for each rack? This would provide independent spaces of segmentation_ids for each. -Bob > > Thanks! > Kyle > >> Thanks >> -- >> Vinay Bannai >> Email: vban...@gmail.com >> Google Voice: 415 938 7576 >> _______________________________________________ >> OpenStack-dev mailing list >> OpenStack-dev@lists.openstack.org >> http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev > > > _______________________________________________ > OpenStack-dev mailing list > OpenStack-dev@lists.openstack.org > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev > _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
