Field Restart Helper Exit Reason Description One of the following values: • Restart Reason - When the router is in helpful neighbor mode, the output includes the restart reason the restarting router sent in its grace LSA. The Restart Reason is the value in the Graceful Restart Reason TLV in the grace LSA sent by the restarting router. Possible values for the Restart Reason are defined in RFC 3623 as follows: - Unknown (0) - Software restart (1) - Software reload/upgrade (2) - Switch to redundant control processor (3) - Unrecognized - a value not defined in RFC 3623 When the switch sends a grace LSA, it sets the Restart Reason to Software Restart on a planned warm restart (when the initiate failover command is invoked), and to Unknown on an unplanned warm restart. • Remaining Grace Time - The number of seconds remaining in the current graceful restart interval. This row is only included if the router is currently acting as a restart helper for the neighbor. • Restart Exit Reason - One of the following: - None - graceful restart has not been attempted - In Progress - restart is in progress - Completed - the previous graceful restart completed successfully - Timed Out - the previous graceful restart timed out - Topology Changed - The previous graceful restart terminated prematurely because of a topology change. A helpful neighbor declares a topology change when it forwards a changed LSA to the restarting router. An LSA is considered changed if its contents are changed, not if it is simply a periodic refresh. show ip ospf range Use the show ip ospf range command in Privileged EXEC mode to display information about the area ranges for the specified area-id.
