Title:
[vpnaas] neutron-vpn-agent is trying to query br-ex link on an
environment that does not use an external_network_bridge
Status in OpenStack Neutron (virtual network service):
Expired
Bug description:
Version
=======
Havana on RHEL
Description
===========
I configured my environment with empty external_network_bridge which means
that it does not uses a br-ex as external bridge, the admin can create a
provider external network.
When trying to start neutron-vpn-agent service, it seems like it tries
to check the link status on br-ex, while br-ex does not appear in any
neutron-related configuration.
