Usage Guidelines
•
Route summarization is the consolidation of addresses within an area which are advertised as a single
route. When network numbers in an area are assigned consecutively, the area border router can be
configured, using this command, to advertise a route that aggregates all the individual networks within
the range.
•
Using this command causes a single route to be advertised, for an address range in the specified area,
to other areas.
