Traffic Engineering

Traffic Engineering (TE) could be considered both an easy and hard topic depending on how it's used. I like to start with the Star Wars Queen Amidala also known as Padme. PADME, this is the most basic route selection order. P - prefix length AD - administrative distance ME - metric Once in the routing table the best route is first chosen by it's prefix length. If both of these are the same the best route is then chosen by the lowest administrative distance and then to the metric. The point is use to manipulate these values in such a way for the route to choose the route you want to a particular destination.

BGP Aggregation
You can remove more specific routes in the BGP table by summarizing routes with summary-only. aggregate-address 14.1.4.0 255.255.255.0 summary-only
