Usage Guidelines

Usage Scenario

After route summarization is configured on an ABR using the abr-summary command, you can run the display ospfv3 abr-summary-list command to view information about summary routes, which facilitates troubleshooting.

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

After route summarization is configured on an ASBR using the asbr-summary command, you can run the display ospfv3 asbr-summary command to view information about summary routes, which facilitates troubleshooting.

Example

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