Enable BGP atomic aggregate
Mark the route as a less specific route because it has been aggregated. ATOMIC_AGGREGATE is a well-known discretionary attribute that alerts BGP speakers along a path that information has been lost due to route aggregation, and therefore the aggregate path might not be the best path to the destination. When some router are aggregated by an aggregator, the aggregator attaches its Router-ID to the aggregated route into the AGGREGATOR-ID attribute and it sets the ATOMIC_AGGREGATE attribute or not, based on whether the AS_PATH information from the aggregated routers was preserved.
Aggregator—Aggregate AS
