Public bug reported: When external bridge is configured in Neutron, the FIP Agent Gateway port 'fg-' is tagged as a DEAD port with Vlan id of 4095.
This issue is seen in Pike. It seems that there was fix that recently merged in neutron shown below https://review.openstack.org/#/c/564825/10 Based on this patch, the 4095 vlan tag for the 'qg-' is removed when external bridge is configured. But it has not been handled for the DVR FIP agent gateway port. So we are seeing the port as DEAD always, when external bridge such as 'br-vlan1087' is configured.
