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 occurs
