A.configure static frame relay map entries for each subinterface network.
B.remove the ip address from the physical interface
C.create the virtual interfaces with the interface command
D.configure each subinterface with its own IP address
E.disable split horizon to prevent routing loops between the subinterface networks
F.encapsulate the physical interface with multipoint PPP

A.Security increases because only the network administrator may change the routing tables.
B.Configuration complexity decreases as network size increases.
C.Routing updates are automatically sent to neighbors.
D.Route summarization iscompued automatically by the router.
E.Routing traffic load is reduced when used in stub network links
F.An efficient algorithm is used to build routing tables，using automatic updates.
G.Routing tables adapt automatically to topology changes.

A.RSTP significantly reduces topology reconverging time after a link failure.
B.RSTP expends the STP port roles by adding the alternate and backup roles.
C.RSTP port atates are blocking,discarding,learing,or forwarding.
D.RSTP also uses the STP proprsal-agreement sequence.
E.RSTP use the same timer-baseed process as STP on point-to-point links.
F.RSTP provides a faster transition to the forwarding state on point-to-point links than STP does.
