Description
Use the abr-summary command to configure automatic route summarization on
the area border router.
Use the undo abr-summary command to disable the function of route
summarization on the area border router.
By default, the area border router does not summarize routes.
This command is applicable only to the area border router (ABR) and is used for
the route summarization in an area. The ABR only transmits a summarized route to
other areas. Route summarization refers to that the routing information is
processed in the ABR and for each network segment configured with route
summarization, there is only one route transmitted to other areas.
You can summarize multiple network segments in one OSPF area.
