Configuring the router to Filter LSAs to Be Sent
Context
When multiple links exist between two routers, you can configure the local router to filter the LSAs to be sent. This prevents transmission of unnecessary LSAs and saves bandwidth resources.
Perform the following steps on the router running OSPF.
Procedure
- Run system-view
The system view is displayed.
- Run interface interface-type interface-number
The interface view is displayed.
- Run ospf filter-lsa-out { all | { summary [ acl { acl-number | acl-name } ] | ase [ acl { acl-number | acl-name } ] | nssa [ acl { acl-number | acl-name } ] } * }
The LSAs to be sent are filtered.
By default, the LSAs to be sent are not filtered.
