The label withdrawal delay timer delays sending a label withdrawal message for a FEC to a neighbor. This feature is enabled by default with a delay of 60 seconds.
To configure the label withdrawal delay timer, perform the following steps.
-
In privileged EXEC mode, enter global configuration mode.
device# configure terminal
-
Enable MPLS on the device.
device(config)# router mpls
-
Access LDP configuration mode.
device(config-router-mpls)# ldp
-
Configure the delay timer.
device(config-router-mpls-ldp)# label-withdrawal-delay 100
In this example, the timer is set to 100 seconds. The default value is 60 seconds.
If you set the timer to 0 (zero), the label withdrawal delay feature is disabled for subsequent events. Any FEC which has already started the label withdrawal delay timer continues to run the timer and to delay sending its label withdrawal messages upstream.
Example
The following example shows the previous configuration steps.
device# configure terminal
device(config)# router mpls
device(config-router-mpls)# ldp
device(config-router-mpls-ldp)# label-withdrawal-delay 100
