suppress-policy route-policy-name: Suppresses specific routes defined in the routing policy. The routing
policy name is a case-sensitive string of 1 to 63 characters.
origin-policy route-policy-name: References the routing policy to specify routes for summarization. The
routing policy name is a case-sensitive string of 1 to 63 characters.
Table 93 Functions of the keywords
Ke
y
words 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.
Usage guidelines
The output interface of a BGP summary route is Null 0. With route summarization, BGP advertises fewer
routes to its peers. A summary route must not be optimal; otherwise, BGP will fail to forward the packets
matching the route. If a summarized specific route has the same mask as the summary route but has a
lower priority, the summary route becomes the optimal route. In this case, you must change the priority
of the summary or the specific route to make the specific route the optimal route.
Examples
# In BGP view, create a summary route 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
# In BGP-VPN instance view, create a summary route of 192. 213.0 .0 / 16 in BGP rout ing table. (The VP N
has been created.)
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ipv4-family vpn-instance vpn1
[Sysname-bgp-ipv4-vpn1] aggregate 192.213.0.0 255.255.0.0
balance (BGP/BGP-VPN instance view)
Use balance to configure the number of BGP ECMP routes.
Use undo balance to disable load balancing.
