Abstract: Techniques are described for specifying and constructing multi-protocol label switching (MPLS) rings. Routers may signal membership within MPLS rings and automatically establish ring-based label switch paths (LSPs) as components of the MPLS rings for packet transport within ring networks. In one example, a router includes a processor configured to establish an MPLS ring having a plurality of ring LSPs. Each of the ring LSPs is configured to transport MPLS packets around the ring network to a different one of the routers operating as an egress router for the respective ring LSP. Moreover, each of the ring LSPs comprises a bidirectional, multipoint-to-point (MP2P) LSP for which any of the routers can operate as an ingress to source packet traffic into the ring LSP for transport to the respective egress router for the ring LSP. Separate protection paths, bypass LSPs, detours or loop-free alternatives need not be signaled.

Abstract: In some embodiments, an apparatus includes a first edge device that is operatively coupled to a second edge device via a switch fabric. The first edge device and the second edge device collectively define an edge device network operating with a network-address-based protocol. The first edge device communicates with the second edge device via a multiprotocol label switching (MPLS) tunnel through the switch fabric. Furthermore, the first edge device is operatively coupled to the switch fabric such that a node of the switch fabric can be modified without coordination of the edge device network. Additionally, the first edge device is operatively coupled to the second edge device to define the edge device network such that an edge device of the edge device network can be modified without coordination of the switch fabric.

Abstract: A method and a network device for enabling communication between unnumbered interfaces are provided. A device level address may be assigned to a network device. The network device may announce the assigned device level address to a neighboring network device over a link. A corresponding device level address associated with the neighboring network device may be received over the link. A route may be stored including the received device level address associated with the neighboring network device and the link. In some implementations, the announcement of the assigned device level address is performed during protocol configuration.
