This document proposes to combine a Backward Recursive or Hierarchical method in Stateful PCE with PCInitiate message to setup independent paths per domain, and combine these different paths together in order to operate them as end-to-end inter-domain paths without the need of signaling session between AS border routers. A new Stitching Label is defined, new Path Setup Types and a new Association Type are considered for that purpose.
