MPLS/GMPLS interworking Signaling aspects Static (GMPLS LSP setup is not triggered by MPLS signaling, e.g., pre-configured or measurement based, e.g., bandwidth on demand) Dynamic (GMPLS LSP setup is triggered by MPLS signaling, e.g. on-demand based on signaling setup request) Routing aspects Border routers advertise setup and hold priority of the GMPLS FA-LSP into MPLS networks. OSPF/ISIS extensions for link priority identification MPLS routers select a GMPLS FA-LSP during SPF calculation.
