Aggregation & Summary

BGP Aggregation (or summarization) is the process of combining multiple specific routes into a single broader route to reduce the size of routing tables. This is crucial for ISP-scale networks to maintain stability and performance.


Boundary Logic: For a prefix to be aggregatable, the constituent subnets must be contiguous. For example, two `/24` subnets (10.0.0.0/24 and 10.0.1.0/24) can be aggregated into a single `10.0.0.0/23` route.

Route Flapping: Summarization also hides "flaps" (routes going up and down frequently) from the rest of the internet, as the summary route remains stable as long as at least one specific route is active.
