Usage
Information
The command area range summarizes routes for the different areas.
With "not-advertise" parameter configured, this command can be used to filter out some external
routes. For example, you want to redistribute static routes to OSPF, but you don't want OSPF to
advertise routes with prefix 1.1.0.0. Then you can configure summary-address 1.1.0.0
255.255.0.0 not-advertise
to filter out all the routes fall in range 1.1.0.0/16.
