Usage 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.
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.
