Quidway S3900 Series Ethernet Switches-Release 1510 Chapter 3 OSPF Configuration Commands

3-2
Use the undo abr-summary command to disable route aggregation on an ABR.
By default, an ABR does not aggregate routes.
This command is applicable to ABRs only and is used for route aggregation in an area.
It allows the ABR to transmit an aggregated route to other areas.
Route aggregation means that routing information is processed by an ABR, which
transmits only one route to other areas for each network segment configured with route
aggregation. You can configure multiple aggregation routes in an area so that OSPF
can aggregate multiple network segments.
Example
# Aggregate the routes in the two network segments, 36.42.10.0 and 36.42.110.0, in
OSPF area 1 into one summary route 36.42.0.0 and transmit it to other areas.
