To remove the MPLS instance, MPLS must be disabled (shutdown) and all SDP bindings to LSPs removed. If MPLS is not shutdown first, when the no mpls command is executed, a warning message on the console displays indicating that MPLS is still administratively up.
When MPLS is shut down, the no mpls command deletes the protocol instance and removes all configuration parameters for the MPLS instance. To disable MPLS, use the shutdown command.
To remove MPLS on a router, enter the following command:
config>router# no mpls
