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; the
value set in that attribute-map will not be shown in the output of the
show ip bgp aggregate route
command.
bgp add-path
Allow the advertisement of multiple paths for the same address prefix without the new paths replacing any previous ones.
Syntax bgp add-path [send | receive | both] path-count
