Exam 300-410 topic 1 question 19 discussion

The correct answer C: Device(config-if)# ospfv3 1 area 1 ipv4 because the question is which command add ipv4 interface to OSPFv3

The answer is C, below the sample config for OSPFv3 R2(config)# router ospfv3 1 R2(config-router)# address-family ipv4 unicast R2(config-router-af)# passive-interface Lo0 R2(config-router-af)# exit R2(config-router)# exit R2(config)# interface Loopback 0 R2(config-if)# ospfv3 1 ipv4 area 1 R2(config-if)# interface Serial 0/0 R2(config-if)# ospfv3 1 ipv4 area 1

C is correct. From Cisco command reference examples: Device(config-if)# ospfv3 1 area 1 ipv4 --- Enables OSPFv3 on an interface with the IPv4 or IPv6 AF. address-family ipv4 unicast --- Enters IPv4 address family configuration mode for OSPFv3.

R1(config-if)#ipv6 enable R1(config-if)#ospfv3 1 ipv4 area 0 R1(config-if)#do show run | sec ospf ospfv3 1 ipv4 area 0 router ospfv3 1 ! address-family ipv4 unicast exit-address-family Lab it people... It's "C"

The correct answer is c

I labbed it and u can't configure af-interface in OSPFv3 address-family unicast routing, so the answer is C.

the correct answer is C. answer D ( even if there no sysntax error) does not adds interface, its just adds the family. the question states " adds a nother interface" meaning - the address family IPV4 unicast is already configured and the command to associate a new interface to OSFPv3 is in answer C

The only method to add an interface on ospfv3 y by interface basis so C is correct

D - because the configuration be applied into process OSPFv3 - D contain 2 commands

Make it simple, the configuration is under an interface, not router configuration mode, A and D are not even relevant to the case

C 100%
