> @Tim, can you please update us on the status of this bug.

We need to fix puppet-opendaylight first. It currently is failing CI because of 
https://git.opendaylight.org/gerrit/#/c/75515/

Then we will need to configure OVSDB in ODL with the incactivity probe timeout. Do we also need to configure the switch with OF inactivity probe timeout as well?

I spoke to Vishal regarding this and the correct approach is to tweak the following file (or the appropriate one) by modifying the elements "<controller-inactivity-probe>"

File: “/var/lib/config-data/puppet-generated/opendaylight/opt/opendaylight/etc/opendaylight/datastore/initial/config/netvirt-elanmanager-config.xml”

Example: <controller-inactivity-probe>xxxxxx</controller-inactivity-probe>

With this configuration in place before starting Karaf, ELAN will pick it and configure OVSDB when creating each bridge on the Nodes. 
This will be used for OVSDB and most-likely even for Openflow connections.
