Border Gateway Protocol IPv4 (BGPv4) | 381
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.
