Usage
Information
At least one of the routes included in the aggregate address must be in the BGP routing table for the
configured aggregate to become active.
Do not add the as-set parameter to the aggregate. If routes within the aggregate are constantly
changing, the aggregate flaps to keep track of the changes in the AS_PATH.
In route maps used in the suppress-map parameter, routes meeting the deny clause are not suppress;
in other words, they are allowed. The opposite is true: routes meeting the permit clause are suppressed.
If the route is injected using the network command, that route stills appear in the routing table if the
summary-only parameter is configured in the aggregate-address command.
The summary-only parameter suppresses all advertisements. If you want to suppress advertisements to
only specific neighbors, use the neighbor distribute-list command.
