View
OSPF Area view
Parameter
ip-address: Network segment address.
mask: Network mask.
advertise : Advertise only the summarized route.
not-advertise : Do not advertise routes matching the specified IP address and mask.
Description
Using abr-summary command, you can configure the route aggregation on the area
border router. Using undo abr-summary command, you can disable the function of
route aggregation on the area border router.
By default, the area border router doesn’t aggregate routes.
This command is applicable only to the area border router (ABR) and is used for the
route aggregation in an area. The ABR only transmits an aggregated route to other
areas. Route aggregation refers to that the routing information is processed in the ABR
and for each network segment configured with route aggregation, there is only one
route transmitted to other areas.
