Configuring Bgp Route Aggregation; Configuring Bgp Route Filtering - H3C SecPath F1800-A Operation Manual

Operation Manual - Network and Routing Protocol
H3C SecPath F1800-A Firewall
Note:
If the import-route command is configured a route-policy with apply clauses (apply A)
to import routes discovered by other protocols, the routes that are sent to the peer will
take effect in turn when the peer is configured an export route-policy with if-match
clauses (if-match A).

6.2.9 Configuring BGP Route Aggregation

BGP supports two types of route aggregation:
summary automatic: aggregates the IGP subnet routes imported by BGP. After
summary automatic is configured, BGP will not receive subnet routes imported
by IGP, but aggregate them to a route in natural network segment.
aggregate: aggregates the local BGP routes. In general, the preference of the
aggregate is higher than that of the summary automatic.
Do as follows in BGP view, multicast sub-address family view or VPN instance view.
