The routing policy name is a string of 1 to 19 characters. 

The keywords of the command are described as follows: 

Table 1-1 Functions of the keywords  

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. 

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. 

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. 

Selects only routes satisfying the routing policy for route summarization.

Sets attributes except the AS-PATH attribute for the summary route. The 
same work can be done by using the peer route-policy command. 

 

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.
