1550 CHAPTER 95: MPLS BASICS CONFIGURATION COMMANDS

	If the interface is bound to a VPN instance, you must use the mpls ldp
	vpn-instancecommand to enable LDP for the VPN instance before enabling LDP
	on the interface to add the interface into the VPN instance.
n	This command supports these interface types: serial interface, async interface,
	Layer 3 Ethernet interface (Ethernet interface, GE interface, and XGE interface),
	ATM interface, POS interface, Layer 3 virtual Ethernet interface (that is,
	virtual-Ethernet interface), virtual template, Mp-group interface, MFR interface,
	tunnel interface, VLAN interface, and virtual dial template (that is, dialer).
Example	# Enable LDP for interface Ethernet 1/0.
	<Sysname> System-view
	[Sysname] interface ethernet 1/0
	[Sysname-Ethernet1/0] mpls
	[Sysname-Ethernet1/0] mpls ldp
mpls ldp advertisement
Syntax	mpls ldp advertisement { dod du }
	undo mpls ldp advertisement
View	Interface view
Parameter	dod: Works in downstream on demand (DoD) mode, advertising a label to FEC
	binding in response to the explicit request of an upstream LSR.
	du: Works in downstream unsolicited (DU) mode, advertising label to FEC bindings
	to LSRs without explicitly requesting bindings.
Description	Use the mpls ldp advertisement command to specify the label advertisement
	mode.
	Use the undo mpls ldp advertisement command to restore the default.
	By default, DU mode is used.
	Note that changing the label advertisement mode will cause the existing sessions
	to be reestablished, and the LSPs established by the sessions to be deleted and
	reestablished.
Example	# Set the label advertisement mode to DoD.
	<Sysname> System-view
