Establishing an inter-area MPLS TE tunnel over a CRLSP
calculated by PCEs
Network requirements
Router A, Router B, Router C, and Router D support MPLS TE and run OSPF.
Configure Router A and Router B as PCEs, and configure Router C as a PCC to automatically
discover the PCEs.
Establish an MPLS TE tunnel over a CRLSP from Router C to Router D that uses the inter-area path
calculated by PCEs.
