Two strategies are outlined right here. The one-to-one backup methodology creates detour LSPs for every protected LSP at each potential level of local repair. The ability backup method creates a bypass tunnel to guard a possible failure level; by making the most of MPLS label stacking, this bypass tunnel can protect a set of LSPs which have related backup constraints. Each strategies can be used to protect hyperlinks and nodes throughout community failure. The described behavior and extensions to RSVP allow nodes to implement both methodology or both and to interoperate in a combined community. [Requirements Observe]
