DELL 9.8(0.0) User Manual

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.
