Aggregation and Suboptimal Routing

This is a continuation from the last topic: route aggregation.

When you advertise an aggregate, you effectively ‘hide’ topological information and can cause suboptimal routing. If you have and summarized into and advertised via two links, one of the links may be the ‘best’ path for the traffic to take, but since the rest of your network has no knowledge of the real ‘best’ path, it may take a suboptimal route.
