The BGP Prefix-Based Outbound Route Filtering feature uses Border Gateway Protocol (BGP)
outbound route filter (ORF) send and receive capabilities to minimize the number of BGP updates that
are sent between peer routers. The configuration of this feature can help reduce the amount of resources
required for generating and processing routing updates by filtering out unwanted routing updates at the
source. For example, this feature can be used to reduce the amount of processing required on a router
that is not accepting full routes from a service provider network.
