<div class="PlainText">Thanks Moshe and Trinath. We found out the issue.<br>
We were using the stable pike branch of networking-odl.<br>
This is where it failed:<br>
<a href="https://github.com/openstack/networking-odl/blob/stable/pike/networking_odl/ml2/pseudo_agentdb_binding.py#L366">https://github.com/openstack/networking-odl/blob/stable/pike/networking_odl/ml2/pseudo_agentdb_binding.py#L366</a><br>
<br>
Now that we migrated to the master branch of networking-odl, it's<br>
working for us.<br>
<br>
Regards,<br>
Pranab<br>
