Configuring MPLS on a Frame Mode Interface

`Router(config)#``mpls ip`	Enables MPLS globally on the router NOTE: MPLS is enabled by default on Cisco routers. However, if you need to re-enable it, use the global mpls ip command.
`Router(config)#``interface fastethernet 0/0`	Moves to interface configuration mode
`Router(config-if)#``mpls ip`	Enables MPLS on the specified interface
`Router(config-if)#``mpls label protocol tdp`	Enables Tag Distribution Protocol (TDP) on this interface NOTE: TDP is Cisco proprietary. LDP is a superset of TDP. Cisco is changing from TDP to a fully compliant LDP.
`Router(config-if)#``mpls label protocol ldp`	Enables Label Distribution Protocol (LDP) on this interface NOTE: LDP is the default protocol on Cisco IOS Release 12.4(3) and later. In older releases, TDP was the default protocol.
`Router(config-if)#``mpls label protocol both`	Enables both TDP and LDP on this interface
