[多选] Company has a Catalyst 6500 and you need to configure redundancy between the supervisormodules. With route processor redundancy （RPR+）， the redundant supervisor engine is fullyinitialized 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 supervisorengine switched over the failed primary supervisor engine？（）

A . Static IP routes are maintained across a switchover because they are configured from entries inthe configuration file
B . Information about dynamic routing states， maintained on the active supervisor engine， issynchronized to the redundant supervisor engine and is transferred during the switchover
C . Information about dynamic routing states， maintained on the active supervisor engine， is notsynchronized 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， routedtraffic is interrupted until route tables reconverge
E . Static IP routes are cleared across a switchover and recreated from entries in the configurationfile on the redundant supervisor engine
F . The Forwarding Information Base （FIB） tables are maintained during the switchover. As aresult， routed traffic continues without any interruption when the failover occur
