Hi Srikanth,

I think you're hitting [1], which I believe has a pending patch in master.

Subject: br-int become slave and disconnect from ODL

Hi,
I am trying to integrate Openstack with ODL.
I am using ODL Boron stable release and OVS 2.6.1. I started ODL karaf using the below command:

/opt/distribution-karaf-0.5.3-SNAPSHOT/bin# ./karaf -of13 clean
Apache Karaf starting up. Press Enter to open the shell now...

Karaf started in 273s. Bundle stats: 389 active, 401 total

and '[cmd] --help' for help on a specific command.
Hit '<ctrl-d>' or type 'system:shutdown' or 'logout' to shutdown OpenDaylight.

And, executed below command to set manager to ODL:

#> ovs-vsctl set-manager tcp:10.20.0.26:6640

ODL able to add br-int to OVS. Following are the OVS details:

root at node-4446ubuntu:~# ovs-vsctl show
9bf5a6cb-e906-4205-afb2-14bb31510a51
    Manager "tcp:10.20.0.26:6640"
        is_connected: true
    Bridge br-int
        Controller "tcp:10.20.0.26:6653"
        fail_mode: secure
        Port br-int
            Interface br-int
                type: internal

Following are the ovs-vswitchd logs:

I am able to see the following ODL errors in the Karaf logs:

Can anyone let me know what could be the issue?
