This is caused because the ext-routers is not created. Seems to be a duplicate root cause of NETVIRT-304 which Olga is currently working on.

To identify this bug, you can see the following log line:
2016-12-12 14:44:05,809 | ERROR | ool-46-thread-15 | NeutronvpnNatManager | 321 - org.opendaylight.netvirt.neutronvpn-impl - 0.3.2.SNAPSHOT | Creation of extrouters failed for router a47a1a5a-9247-4a77-959b-9915d3c6c095 failed with null
