BGP Lab Tips

  • unsuppressĀ -map – use this with a route-map that contain specific routes you wish a neighbour to know in case you are summarising using, say, the aggregate-address command.
  • Weight and Local Preference will affect how traffic leaves your AS
  • MED and AS-PREPEND will affect how traffic enters your AS
  • send-community both is needed when setting BGP attributes like no-export
  • Condition-map uses reverse logic. We check to see if a route does NOT exist before we advertise.
