generate_as_set
as_set Generates AS path information
Form a verbose aggregate, whose AS path contains a leading AS
sequence representing the common leading sequence of all
contributing routes, and whose AS path contains a trailing AS set
representing all ASes in all contributing paths that could not be
included in the AS sequence. By default, this feature is off, and the AS
path is truncated when the aggregate is formed.
generate_summary_only
summary_only Filters more specific routes from updates
Suppresses transmission of any contributing routes if an aggregate
exists. Note that the contributing route will not be sent even if an
outgoing route_map blocks the sending of the aggregate itself. This
cannot be combined with the suppress_map parameter.
suppress_map Name of the route map to suppress
Uses the named route_map to suppress the transmission of selected
contributing routes. Contributing routes that do not match the
route_map will not be suppressed. This cannot be combined with the
summary_only parameter.
advertise_map Name of route map to control attribute advertisement
Selects the routes that contribute to the aggregate. The aggregate will
only be formed if matching routes exist. Only the matching routes will
be suppressed if summary_only or suppress_map are configured.
attribute_map Name of route map for setting attributes
Specifies attributes to be set on the aggregate when it is transmitted.
