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 will flap 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 via the network command, that route will still 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.
