Hello,
I have a BGP network that I am trying to be more efficient with. Just trying to advertise one summary route into the provider cloud. I have an internal routingprotocal of OSPF that I am redistrubuting into BGP via a route map (this is so I can control what I send into BGP). However I then would like to only send a summary route into the proiders AS. I am not doing something correctly as when I look at the routes advertised into the providers AS I see the summary route and the routes with longer prefixes that I am trying to hide.
Andy
Any advise would be appreciated.
