Modes OSPF Router Configuration

nsf helper strict-lsa-checking

The restarting router is unable to react to topology changes. In particular, the restarting router
will not immediately update its forwarding table; therefore, a topology change may introduce
forwarding loops or black holes that persist until the graceful restart completes. By exiting the
graceful restart on a topology change, a router tries to eliminate the loops or black holes as
quickly as possible by routing around the restarting router. A helpful neighbor considers a link
down with the restarting router to be a topology change, regardless of the strict LSA checking
configuration.
Use this command to require that an OSPF helpful neighbor exit helper mode whenever a
topology change occurs.
Default Enabled.
