DETAILED STEPS
Setting the Allocation Algorithm for MPLS Safe Label Reuse
Perform the following tasks to set the algorithm to use for the allocation of MPLS labels.
Refer to the
for a description of
the available allocation algorithms.
SUMMARY STEPS
1.
enable
2.
configure terminal
3.
mpls label restart
Command or Action
Purpose
Step 1
enable
Example:
Router> enable
Enables privileged EXEC mode.
•
Enter your password if prompted.
Step 2
configure
terminal
Example:
Router# configure terminal
Enters global configuration mode.
Step 3
mpls label restart
Example:
Router(config)# mpls label restart
Enters mpls-label-restart configuration mode to configure
parameter settings that govern MPLS label usage following
a router restart.
parameter settings that govern MPLS label usage following
a router restart.
Step 4
pdata absent state free
Example:
Router(mpls-label-restart)# pdata absent state
free
Sets the state of all MPLS labels to the free state when
persistent data describing MPLS label usage is not found
following a router restart.
persistent data describing MPLS label usage is not found
following a router restart.
•
The no form of this command sets all the MPLS labels
to the in-use state if no persistent data is found
following restart.
to the in-use state if no persistent data is found
following restart.
Step 5
end
Example:
Router(mpls-label-restart)# end
Exits to privileged EXEC mode.
