View	MPLS view
Parameter	explicit-null: Specifies that the egress does not support PHP and distributes to the
	penultimate hop an explicit null label, whose value is 0.
	implicit-null: Specifies that the egress supports PHP and distributes to the
	penultimate hop an implicit null label, whose value is 3.
	non-null: Specifies that the egress distributes the label to the penultimate hop
	normally and does not support PHP. The value of the distributed label will be equal
	to or greater than 1024.
Description	Use the label advertise command to specify whether the egress supports PHP
	and what type of label the egress should distribute to the penultimate hop.
	Use the undo label advertise command to restore the default.
	By default, an egress supports PHP and distributes to the penultimate hop an
	implicit null label.
n	■ The type of label for the egress to distribute depends on whether the
	penultimate hop supports PHP.
	■ You must use the reset mpls ldp command to reset LDP sessions for the
	configuration to take effect.
Example	# Specify the egress to distribute an explicit null label to the penultimate hop.
