Centralized Protection: Riverhead Long Diversion Method Using MPLS LSP
... While the Guard is at the end of the LSP path, it is not required to run MPLS; it only receives pure IP due to the fact that R1 is the egress proxy LSP path for the Guard. In other words, R1 performs penultimate hop popping on the MPLS packets that arrive at the Guard’s loopback and shoots them dire ...
