In a fresh installation create a tenant neutron network, subnet and router.<br/> 2. Associate the subnet to the neutron router.<br/> 3. In karaf cli, check the ELAN instances.<br/> opendaylight-user@root&gt;elan:show <br/> 4. You would see an ELAN instance created for the resources.<br/> 5. Now dissociate the tenant subnet from neutron router, delete the router, network and subnet.<br/> 6. Check elan instances.<br/> You will see the same output as in Step 3 above.</p> <p>Expected behavior:<br/> The ELAN instances should have been deleted.</p> <p>Along with this, the following exception is logged in karaf.<br/> 2017-01-17 16:30:12,135 | ERROR | pool-43-thread-1 | InterfacemgrProvider | 335 - org.opendaylight.genius.interfacemanager-impl - 0.1.2.Boron-SR2 | Interface b1c4af31-b2eb-4cb7-8aff-f67fdbd1e8ac is not present<br/> Exception in thread "pool-43-thread-1" java.lang.NullPointerException<br/> at java.util.concurrent.ConcurrentHashMap.get(ConcurrentHashMap.java:936)<br/> at java.util.concurrent.ConcurrentHashMap.containsKey(ConcurrentHashMap.java:964)<br/> at java.util.Collections$SetFromMap.contains(Collections.java:5459)<br/> at org.opendaylight.netvirt.neutronvpn.NeutronvpnUtils.isNetworkTypeSupported(NeutronvpnUtils.java:975)<br/> at org.opendaylight.netvirt.neutronvpn.NeutronNetworkChangeListener.remove(NeutronNetworkChangeListener.java:101)<br/> at org.opendaylight.netvirt.neutronvpn.NeutronNetworkChangeListener.remove(NeutronNetworkChangeListener.java:34)<br/> at org.opendaylight.genius.datastoreutils.AsyncDataTreeChangeListenerBase$DataTreeChangeHandler.run(AsyncDataTreeChangeListenerBase.java:129)<br/> at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142)<br/> at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617)<br/> at java.lang.Thread.run(Thread.java:745)</p> <p>Operating System: All<br/> Platform: All</p> NETVIRT-438
