Garry,
Here is my understanding about the above command from Jeff Doyle's Bible :-)
When ABR is also ASBR the default behaviour is to redistribute the external
routes as N in NSSA in order to avoide this default behaviour we use the
above command which would not advertize external routes in the NSSA area and
give us so called "Not so stubby" Stubby area
Hope this helps
Sandro
