 Description   

When the below topology modules are stopped through osgi cli, the topology is getting updated when the nodeconnector is brought down

osgi> ss | grep topology

Test case:
=========
->Create a 2 switch topology to 2 hosts topology is created. Send the table miss flows to the switches.
->Make a GET request to the controller with URL:
http://<controller ip>:8080/restconf/operational/network-topology:network-topology/topology/flow:1
->Now the get response has the link information.
->Stop the above bundles in osgi cli.
->Bring down the link in the switch.
->Make a GET request for the topology:
http://<controller ip>:8080/restconf/operational/network-topology:network-topology/topology/flow:1
The get response does not contain the link information.

Could you please explain why the link status is getting updated when the listeners are stopped.

Thanks,
Sindhuri.

Although this bug is put under openflowplugin, the fix lies in MD-sal's topology manager.
I have submitted a patch and its in the WAITING_FOR_REVIEW state
