Control plane driven summarization in a network

Techniques for dynamically adapting a router capacity to system needs in a network. The border router may receive a list of summarized prefixes for endpoint devices associated with the router from control-plane nodes. The router may store the list of summarized prefixes in memory of the border router. Once the router receives traffic that is destined for endpoint devices associated with the border router, it may determine that the destination address is included in the summarized prefixes. In some examples, the router may download complete prefixes from the control-plane nodes, and forward the traffic to the destination address indicated by the complete prefixes.
