2. Show the OSPF interface status
The following message shows that the F0/1 port belongs to area 0 of the OSPF, and the
device ID is 172.16.120.1. The network type is ―BROADCAST‖-broadcast type. You must
pay special attention to the parameters such as Area, Network Type, Hello and Dead. If
these parameters are different from the neighbor, no neighborhood relationship will be
established.
