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.
