Well, this is exactly what Doyle has in Vol 2 p.188 where the router CONFIGURED with thte "aggregate-address" command shows the more-specific routes in its BGP table with S> entries and to suppress the more-specific routes you add the "no-summary" keyword. Doyle's config clearly has the "network" statements removed to prove this behavior. Thanks for the replies. Elmer
