Node-Wide MPLS-TP Parameter Configuration

Generic MPLS-TP parameters are configured under config>router>mpls>mpls-tp. If a user configures no mpls, normally the entire MPLS configuration is deleted. However, in the case of MPLS-TP a check that there is no other MPLS-TP configuration; for example, services or tunnels using MPLS-TP on the node, is performed.

The MPLS-TP context is configured as follows:

config
   router
      mpls
         [no] mpls-tp
            . . . 
            [no] shutdown 

MPLS-TP LSPs may be configured if the MPLS-TP context is administratively down (shutdown), but they remain down until the MPLS-TP context is configured as administratively up. No programming of the data path for an MPLS-TP path occurs until the following are all true:

A shutdown of MPLS-TP therefore brings down all MPLS-TP LSPs on the system.

The MPLS-TP context cannot be deleted if MPLS-TP LSPs or SDPs exist on the system.
