ORA-12514 during Switchover using DG broker with multiple IP segment

Our new system 2 node RAC Oracle 11.2.0.2 are setup with 1 instance of Standby database. Yesterday we tested to switchover to standby database using 'dgmgrl'. The switchover was ok , only that my Primary Node (Node1) was not automatically restarted instead throwing ORA-12514 - TNS:listener does not currently know of service requested in connect descriptor. 

I checked all my listener for DG broker have been setup with static listener, which usually this is the cause of this error. Everything looks properly setup until I checked each instance Broker configuration "StaticConnectIdentifier"(New parameter in 11g) property :

dgmgrl > show instance verbose "PRD1"

...

StaticConnectIdentifier='(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=172.22.2.29)(PORT=1532))(CONNECT_DATA=(SERVICE_NAME=PRD_DGMGRL)(INSTANCE_NAME=PRD1)(SERVER=DEDICATED)))';

dgmgrl > show instance verbose "PRD2"

StaticConnectIdentifier='(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=172.22.2.30)(PORT=1532))(CONNECT_DATA=(SERVICE_NAME=PRD_DGMGRL)(INSTANCE_NAME=PRD2)(SERVER=DEDICATED)))';

Well, we configure all the static listener on 172.22.12.7 (VIP1 - Segment 12) and 172.22.12.9 (VIP2 - Segment 12). I remember that IP segment 172.22.2.xx was the initial VIP segment during the installation. 

Then I just change it to the correct IP and port number.

dgmgrl> edit instance 'PRD1' set property StaticConnectIdentifier='(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=172.22.12.7)(PORT=1523))(CONNECT_DATA=(SERVICE_NAME=PRD_DGMGRL)(INSTANCE_NAME=PRD1)(SERVER=DEDICATED)))';

dgmgrl> edit instance 'PRD2' set property StaticConnectIdentifier='(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=172.22.12.9)(PORT=1523))(CONNECT_DATA=(SERVICE_NAME=PRD_DGMGRL)(INSTANCE_NAME=PRD2)(SERVER=DEDICATED)))';

After this changes my switchover was running smoothly without any error. Problem solved!
