Table 214 Functions of the keywords

Keywords	Function
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 a summary route in the BGP routing table.

Use the undo aggregate command to remove a summary route.

By default, no summary route is configured.
