Comment 5 for bug 1338880

This bug has not been completely fixed. Any user can still unset the network from being external.

The change in the test of the description would be:

with network(name="UpdateNetworkExternalRouter", tenant_id=ProjectA, router_external=True) as test_network:
            self.project_member_a_neutron_client.update_network(network=test_network, router_external=False)
