Command History
Version Description
9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
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.
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
Parameters
send Enter the keyword send to indicate that the system sends
multiple paths to peers.
receive Enter the keyword receive to indicate that the system
accepts multiple paths from peers.
