[OPNFLWPLUG-728] Entity Owner not resolved properly after owner is isolated or rejoined with iptables

Blocks — Mon, 27 Sep 2021 09:01:51 +0000

To reproduce install controller cluster in Be or B and:

1) Connect switch to 3 nodes
2) Find out switch owner
3) isolate owner from other nodes using iptables:
sudo iptables -A OUTPUT -d

{other-controller-IP} -j DROP
sudo iptables -A OUTPUT -d {other-controller-IP}

-j DROP
4) Check entity ownership in cluster node
5) after a while rejoin the cluster:
sudo iptables -D OUTPUT -d

{other-controller-IP} -j DROP
sudo iptables -D OUTPUT -d {other-controller-IP}

-j DROP
6) Check entity ownership in cluster node

Either 4) or 6) fails sporadically.
