4.2.2 Entering OSPF Area view
Perform the following configurations in OSPF view.
Table 4-2 Entering OSPF Area view
Enter OSPF Area view
delete a designated OSPF area
area-id: ID of the OSPF area, which can be a decimal integer or in IP address format.
4.2.3 Specifying interface
OSPF further divides the AS into different areas. An area logically groups the routers.
Some routers belong to different areas (such routers are called ABRs), but one
segment can only belong to an area. In other words, you must specify each OSPF
interface to belong to a particular area identified by area ID. The areas transfer routing
information between them via the ABRs.
In addition, parameters of all the routers in the same area should be identical.
Therefore, when configuring the routers in the same area, please note that most
configurations should be based upon the area. Wrong configuration may disable the
neighboring routers to transmit information between them, and even lead to congestion
or self-loop of the routing information.
Perform the following configuration in OSPF Area view.

You must specify the segment to which the OSPF will be applied after enabling the

ip-mask: IP address wildcard shielded text (similar to the complement of the IP address
