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.
