Usage Information
The area range command summarizes routes for the different areas.
With the not-advertise parameter configured, you can use this command to filter out some external routes.
For example, if you want to redistribute static routes to OSPF, but you don't want OSPF to advertise routes with
prefix 1.1.0.0, you can configure the 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.
