	specifying the command in interface configuration mode.
Router(config)# mpls label protocol ldp
Router(config)# interface type number	Specifies the interface to be configured and enters interface
	configuration mode.
Example:
Router(config)# interface ethernet3/0
mpls ip	Configures MPLS hop-by-hop forwarding on the interface.
	• You must enable MPLS forwarding on the interfaces as well
Example:	as for the router.
Router(config-if)# mpls ip
exit	Exits interface configuration mode and enters global configuration
	mode.

Router(config-if)# exit

	mode.
Example:
Router(config)# exit
show mpls interfaces [interface] [detail	Verifies that the interfaces have been configured to use LDP, TDP,
	or both.
Example:
