    Description

      In OVSDB Single node clustering 2 switches registered with same manager there are two "OWNER" founds in southbound, and with this two "OWNER" replication happens

      Observation : 1 (A Switch registered with manager) - one "OWNER" found

      Here switch ip is : 10.106.138.114
