This command is disabled by default.
� This command enables LDP to exchange labels on the interface
of layer 3. Once the command is configured, LSR starts to pe-
riodically send hello messages on the interface. When packets
to the destination network obtain the outgoing label to some
destination network, the outgoing label will be added into the
packets and the packets will be forwarded from this interface.
Note that this command will take effect only after mpls ip is
configured in global configuration mode.
� The no form of this command make packets routed from this
interface no more carry labels and cease the label switching on
the interface.
This example describes how to enable LDP on the interface fei_1/1.
