The advertise-map <map-name> parameter configures the router to advertise the more specific
routes in the specified route map.
The attribute-map <map-name> parameter configures the router to set attributes for the aggregate
routes based on the specified route map.
NOTE
For the suppress-map, advertise-map, and attribute-map parameters, the route map must already
be defined. Refer to “Defining route maps” on page 1042 for information on defining a route map.
