Function
Enables the summary route to carry the AS path information of all summarized routes.
This feature can help avoid routing loops. However, if many routes are summarized and
are changed frequently, do not specify this keyword because this configuration causes
the summary route to flap with the more specific routes.
Sets attributes except the AS-PATH attribute for the summary route. The peer route-policy
command can achieve the same purpose.
Disables advertisement of all more specific routes. To disable advertisement of some
more specific routes, use the suppress-policy keyword or the peer filter-policy
command.
Summarizes only routes satisfying a routing policy.
If the destination address of a route falls within the summary network but does not match
the routing policy, the route is not summarized, and is not controlled by the
detail-suppressed and suppress-policy keywords.
There is no need to configure apply clauses for the routing policy referenced by the
origin-policy keyword because they do not take effect.
Disables advertisement of some more specific routes filtered by a routing policy. The
routing policy uses if-match clauses to filter routes.
There is no need to configure apply clauses for the routing policy referenced by the
suppress-policy keyword because they do not take effect.
