in global configuration mode. To disable this option for the specified neighbor, use the no form of this
command.

Syntax Description
Defaults When the vr
f keyword is not specified in this command, the label distribution protocol (LDP) neighbor
is configured in the default routing domain.
If this command is not configured, when it is necessary for LDP to change the label it has advertised to
a ne
ighbor for some prefix, it will withdraw the previously advertised label before advertising the new
label to the neighbor.
For the no
form of the command, if the implicit-withdraw keyword is not specified, all configuration
information for the specified neighbor reverts to the defaults and the neighbor record is deleted.
