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.
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.
