Usage Information
At least one of the routes included in the aggregate address must be in the BGP routing table for the
congured 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 aps 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 congured in the aggregate-address command.
The summary-only parameter suppresses all advertisements. If you want to suppress advertisements to
only specic neighbors, use the neighbor distribute-list command.
In the show ip bgp command, aggregates contain an ‘a’ in the rst column and routes suppressed by the
aggregate contain an ‘s’ in the rst 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.
