Abstract
The distribution of reachability information between data centers includes receiving routes that are advertised among network devices within a given data center. The received routes are summarized to produce one or more summarized (aggregated) routes which are fewer in number than the received routes. Instead of advertising the received routes among the data centers, the summarized routes are advertised. Advertising the summarized routes as compared to the received routes reduces control plane traffic between data centers, and reduces the requirements for storing advertised routes received by a data center.
