By default, no summary route is configured.
Examples
# In BGP view, create a summary of 192.213.0.0/16 in the BGP routing table.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] aggregate 192.213.0.0 255.255.0.0
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 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.
