Command History
This guide is platform-specic. For command information about other platforms, refer to the relevant Dell
Networking OS Command Line Reference Guide.
The following is a list of the Dell Networking OS version history for this command.
Version 8.3.19.0 Introduced on the S4820T.
Version 8.4.2.1 Introduced on the C-Series and S4810.
Version 7.4.1.0 Introduced on the E-Series TeraScale.
Usage Information
At least one of the routes included in the aggregate address must be in the BGP routing table for the
congured aggregate to become active.
Do not add the as-set parameter to the aggregate. If routes within the aggregate are constantly changing,
the aggregate aps 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 true: routes meeting the permit clause are suppressed.
If the route is injected using the network command, that route stills appear in the routing table if the
summary-only parameter is congured in the aggregate-address command.
The summary-only parameter suppresses all advertisements. If you want to suppress advertisements to
only specic neighbors, use the neighbor distribute-list command.
