There is no summary address range of the specified area by de-
fault.
� This command is supported after the platform version 4.6.02.

This command is only applicable to the area border routers. It
is used to make a combination of computation and a summary
of routes in an area. As a result, an outline route is advertised
to the other areas by the ABR. The information of the route-
choosing is compressed at the area border.
� Only the corresponding routes of type 1 and type 2 LSA can be
summarized.
� If the area does not exist, it will be created automatically.
In this example, the networks of area 1 are aggregated into area
0, and type 3 LSA is advertised.
