Usage Guidelines

Usage Scenario

Route summarization reduces the amount of routing information transmitted between areas and the routing table size and improves routing performance.

After route summarization is configured using the asbr-summary command, you can run the display ospf asbr-summary command to view the route summarization information, which facilitates troubleshooting.

The actual command output varies according to the device. The command output here is only an example.
