Refer to the exhibit.Which command must be applied to R2 for an OSPF neighborship to form?
- A. network 126.96.36.199.0.0.0.0 area 0
- B. network 188.8.131.52 255.255.0.0. area 0
- C. network 184.108.40.206.0.0.255.255 area 0
- D. network 220.127.116.11 255.255.255 area 0
Explanation: The network 18.104.22.168 0.0.0.255 area (” command on R2 did not cover the IP address of Fal/1 interface of R2 so OSPF did not run on this interface. Therefore we have to use the command “network 22.214.171.124 0.0.255.255 area 0” to turn on OSPF on this interface.
Note: The command “network 126.96.36.199 0.0.255.255 area 0” can be used too so this answer is also correct but answer C is the best answer here.
network 0.0.0.0 255.255.255.255 area 0 command on R1 will run OSPF on all active interfaces of R1.
