Claim:
1. A method comprising: generating, with an ingress router of a label switched path (LSP) that admits network packets into the LSP and forwards the network packets toward an egress router of the LSP, a path message for establishing the LSP in accordance with a multi-protocol label switching (MPLS) protocol, the path message indicating that a label allocated and bound to the LSP by a router positioned along the LSP between the ingress router and the egress router of the LSP is to be sent upstream by the router toward the ingress router prior to the router confirming that a forwarding plane within the router has been configured to use the bound label to forward the network packets; and outputting, with the ingress router and toward the egress router, the path message to initiate establishment of the LSP.
