Command Modes ROUTER BGP Address Family (conf-router_bgp_af)
Command History
Version 9.0(1.3) Introduced on the S5000.
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.
