Reference Guide

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.
