pany has a Catalyst 6500 and you need to configure redundancy between the supervisor  modules. With route processor redundancy （RPR+）， the redundant supervisor engine is fully initialized and configured， which shortens the switchover time if the active supervisor engine fails.   Which three statements are true about the RPR + operations when the redundant supervisor  engine switched over the failed primary supervisor engine？ （）

• A、 Static IP routes are maintained across a switchover because they are configured from entries in  the configuration file.
• B、 Information about dynamic routing states， maintained on the active supervisor engine， is  synchronized to the redundant supervisor engine and is transferred during the switchover.
• C、 Information about dynamic routing states， maintained on the active supervisor engine， is not  synchronized to the redundant supervisor engine and is lost on switchover.
• D、 The Forwarding Information Base （FIB） tables are cleared on a switchover. As a result， routed  traffic is interrupted until route tables reconverge.
• E、 Static IP routes are cleared across a switchover and recreated from entries in the configuration  file on the redundant supervisor engine.
• F、 The Forwarding Information Base （FIB） tables are maintained during the switchover. As a  result， routed traffic continues without any interruption when the failover occurs.
