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.
