An HP Comware switch is controlled by a team of HP VAN SDN Controllers. The controllers have these roles within the region that contains the switch.
Controller 1 = Master
Controller 2 Primary slave
Controller 3 =Secondary slave
A failed network connection causes Controller 1 to lose contact with the switch. Controller 2 and Controller 3 can still reach all the controlled devices. Controller 1 is still up and has contact with other controllers and switches. How does the team handle this situation?
A. Controller 1, as master, contacts OpenFlow-enabled devices near the switch and attempts to repair the connection.
B.Controller 2 becomes the master for this switch, although Controller 1 remains master for other switches.
C. Controller 1, as master, removes the switch from any active flows and sends updated flows to Controller 2 andController 3.
D.Controller 2 becomes the master for all switches in the region, and Controller 1 becomes the primary slave for the region.
