Parameters
explicit-null: Specifies the egress to advertise an explicit null label of 0 to the penultimate hop.
implicit-null: Specifies the egress to advertise an implicit null label of 3 to the penultimate hop.
non-null: Specifies the egress to advertise a normal label to the penultimate hop. The value range for a
