I’m doing some testing/PoC on an RDO Ocata CentOS7 setup and everything has gone well with the exception of configuring multiple VLANs.
After following the configuration detailed at https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/10/html/networking_guide/sec-connect-instance#Using-VLAN-Provider-Networks , neutron errors out with the following: $ neutron net-create 1_network \ --provider:network_type vlan \ --router:external true \ --provider:physical_network extnet \ --provider:segmentation_id 1 --shared Unable to create the network. The VLAN 1 on physical network extnet is in use. extnet is mapped to the OVSbridge br-ex, which has a physical interface that’s trunked to all of the available VLANs..trying this command on the other available VLANs works, but 1 and 2 (the ones I want to test on) always fails. Is there anything obvious to try on the system itself or is this more likely a network issue? Thanks much,
