Usage Guidelines
The strict LSA checking feature allows a helper router to terminate the graceful restart process if it detects a changed LSA that would cause flooding during the graceful restart process. Strict LSA checking is disabled by default. You can enable strict LSA checking on an OSPF helper to have the router terminate graceful restart when there is a change to an LSA that would be flooded to the restarting router. This feature takes effect only when the router is in helper mode.
Example
- Configure strict Enable strict LSA checking on the Helper Router.
