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.

If routes within the aggregate are constantly changing, do not add the as-set

parameter to the aggregate as 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 also true:

routes meeting the permit clause are suppressed.

If the route is injected via the network command, that route still appears 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.

In the show ip bgp command, aggregates contain an 'a' in the first column and

routes suppressed by the aggregate contain an 's' in the first column.

When an aggregate address is denied using a peer's outbound route-map,

individual routes suppressed by the aggregate address are advertised to that peer.

The attribute-map corresponding to an aggregate address is applied during the

outbound update creation time; hence the value set in that attribute-map will not

be shown in the output of the show ip bgp aggregate route command.
