You want to classify and mark the packets that are received by a router from a Catalyst 2900 XL. Your supervisor wants you to retag the packets at the router. The connection from the switch to the router must be a trunk in order to carry the Layer 2 CoS markings. The router interface is a Fast Ethernet interface. Which three steps will you use to correctly map 802.1p to DSCP on this L2 switch to accomplish this task? (Choose three.)
A.
router(config)#class-map match-any CoS5 router(config-cmap)#match cos 5
B.
router(config)# policy-map dot1p-to-DSCP router(config-pmap)# class CoS5 router(config-pmap-c)#set dot1p dscp AF11
C.
router(config)# interface fa0.1 router(config-subif)#encapsulation 802.1p router(config-subif)#service-policy input DSCP-to-CoS
D.
router(config)#class-map match-any 802.1p router(config-cmap)#match dscp 5
E.
router(config)# policy-map CoS-to-DSCP router(config-pmap)# class CoS5 router(config-pmap-c)#set ip dscp AF11
F.
router(config)# interface fa0/0.1 router(config-subif)#encapsulation isl 1 router(config-subif)#service-policy input CoS-to-DSCP
