Configuring BGP Route Summarization

To reduce the routing table size on medium and large BGP networks, you need to configure route
summarization on BGP routers. BGP supports two summarization modes: automatic and manual.
Manual summary routes enjoy a higher priority than automatic ones.
Configure automatic route summarization
After automatic route summarization is configured, BGP summarizes redistributed IGP subnets to
advertise only natural networks. Routes injected with the network command can not be summarized.
Follow these steps to configure automatic route summarization:
To do...
Enter system view
Enter BGP view
Use the command...

bgp as-number
import-route protocol
[ process-id | all-processes ]
[ med med-value |
