How to use vlan in public network
I have an external physical network which is used as public network. Network admins gave me one vlan (say 10). While creating external bridge I created its internal tagged interface and it is able to reach other devices in this network. Nonetheless, when neutron creates its external interfaces in the bridge, they appear untagged, so they cannot reach others. What should I do so that neutron forced to create routers' external interfaces with tags? Thanks in advance.
Is this the ovs plugin? Try creating a subinterface with vlan id 10 from the main interface, and add it to bridge br-ex instead of the main interface.
Unfortunately I cannot do that because I have another vlans in the same bridge for management and storage networks. Any other opinions?
