the interface is in the desired area.

Meaning
The output shows a list of the Services Router interfaces that
are configured for OSPF. Verify the following information:
Each interface on which OSPF is enabled is listed.
Under Area, each interface shows the area for
which it was configured.
Under Intf and State, the Services Router
loopback (lo0.0) interface and LAN interface that are linked
to the OSPF network's designated router (DR) are identified.
Under DR ID, the IP address of the OSPF network's
designated router appears.
Under State, each interface shows a state of PtToPt to indicate a point-to-point connection. If the state
is Waiting, check the output again after several seconds.
A state of Down indicates a problem.
The designated router addresses always show a state of DR.
