n
The abr-summary command is available on ABRs only. If contiguous network
segments are available in an area, you can use the command to summarize them
into one network segment on the ABR. The ABR will advertise only the summary
route. Any LSA falling into the specified network segment will not be advertised,
reducing the LSDB size in other areas.
