Usage Guidelines

After an AS is divided into areas, configuring route aggregation can reduce routing information transmitted between areas. This reduces the size of the routing table and improves route performance.

To check information about OSPF route summarization, run the asbr-summary command.

Example

# Display summarization information about all the imported OSPF routes.

<HUAWEI> display ospf asbr-summary
