Abstract:
1. A method for providing scalable engineered bypass connectivity between end-point routers in an MPLS network, the method comprising the steps of: configuring a physical port of a first end-point router on the MPLS network to support a stand-alone Forwarding Instance without an associated Routing Adjacency, the physical port of the first end-point router being connected to an underlying bypass technology supporting the MPLS network using a client-server relationship and enabling connectivity through the bypass technology to implement the Forwarding Instance; configuring a physical port of a second end-point router on the MPLS network to support the same stand-alone Forwarding Instance without an associated Routing Adjacency, the physical port of the second end-point router being connected to the underlying bypass technology supporting the MPLS network, configuring the stand-alone Forwarding Instance on a local end-point router, and associating the Forwarding Instance with an IP address of the remote end-point router and configuring the stand-alone Forwarding Instance on the remote end-point router, and associating the Forwarding Instance with an IP address of the local end-point router, configuring a path to be used by traffic passing over the Forwarding Instance through the bypass technology to associate the path in the bypass technology with the Forwarding Instance between the first and second end-point routers; and establishing an Operation Administration and Maintenance (OAM) session on the Forwarding Instance to verify connectivity on the Forwarding Instance and configuration of the Forwarding Instance.
