Functions of the keywords
Keywords
Function
as-set
Used to create a summary route, whose AS path contains the AS path
information of summarized routes. Use this keyword carefully when many
AS paths need to be summarized, because the frequent changes of these
specific routes may lead to route oscillation.
detail-suppressed
This keyword does not suppress the summary route, but it suppresses the
advertisement of all the more specific routes. To summarize only some
specific routes, use the
peer filter-policy
command.
suppress-policy
Used to create a summary route and suppress the advertisement of some
summarized routes. If you want to suppress some routes selectively and
leave other routes still advertised, use the
if-match
clause of the
route-policy
command.
origin-policy
Selects only routes satisfying the routing policy for route summarization.
attribute-policy
Sets attributes except the AS-PATH attribute for the summary route. The
same work can be done by using the
peer route-policy
command.
Description
Use the
aggregate
command to create an IPv6 summary route in the IPv6 BGP routing table.

undo aggregate
command to remove an IPv6 summary route.
By default, no summary route is configured.
