Controlling route distribution and reception

This section describes how to control route distribution and reception.

Configuring BGP route summarization

Route summarization can reduce the number of redistributed routes and the routing table size. IPv4 BGP
supports automatic route summarization and manual route summarization. Manual summarization takes
precedence over automatic summarization. IPv6 BGP supports only manual route summarization.
