Disable constrained-path LSP computation for this LSP:

LSP that has been set up to that destination:

To configure the egress PE switch:
Configure OSPF (or IS-IS) on the loopback interface (or switch address) and core

Enable traffic engineering for the routing protocol:

Configure an IP address for the loopback interface and for the core interfaces:

Configure MPLS on the core interfaces:
