Usage Guidelines
•
Use the no form of this command to set the Forwarding State Holding timer to the default value.
•
This timer is started if the MPLS forwarding state of the restarting router was preserved after a grace-
ful restart. The router then marks the forwarding entries as "stale" for the length of this time value.
When the timer expires, any entries that are still marked as stale are deleted.
•
An LDP router is considered in the process of restarting if the Forwarding State Holding timer is still
active. When the end of this holding time is reached, the restart process is considered complete for the
router.
•
The Recovery Time advertised in the FT Session TLV of the LDP message is set to the current value
of the Forwarding State Holding timer at the time the message is sent. If the router did not retain its
MPLS forwarding state after a restart, then the Recovery Time is set to zero.
