Yes - definitely desirable, and maybe required. The same provider
attributes are needed to use a provider external network with the
l3-agent. With linuxbridge, this is the only way to define an external
network, and I recommend it for openvswitch (in place of setting
external_network_bridge = br-ex) as well. In general, I think we need to
support both direct access to external networks (as provider networks
that VMs connect to) and routed access to external networks (via
l3-agent + provider network).
