This object indicates any aggregation processing that has been applied to this Adj-RIB-Out route. A value of noAggregation(1) indicates that this route does not aggregate any other routes, and is not aggregated by any route. A value of aggregateRoute(2) indicates that this route is a locally configured aggregating route, corresponding to an entry in the bgpAggregateTable. A value of unsuppAggregatedRoute(3) indicates that this route has been aggregated by a locally configured aggregate route and is not suppressed - the route is still explicitly advertised to the peer. A value of suppressedAggregatedRoute(4) indicates that this route has been aggregated by a locally configured aggregate route and is flagged such that it should not be advertised along with the aggregate route. Typically such routes are not installed on an Adj-RIB-Out. If however the aggregate route itself is not permitted to be added to the Adj-RIB-Out then suppressed routes are advertised if they themselves are permitted by policy.
