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.
