First and second egress nodes are each multi-homed to a customer edge (CE) that participates in virtual routing and forwarding (VRF). First forwarding information is configured on the first egress node. The first information includes VRF labels and defines forwarding of traffic based on the VRF labels and a status of a primary path to the CE. The VRF labels include a per-VRF label for the VRF and a per-CE label for the CE. Second forwarding information is configured on the second egress node. The second forwarding information includes the per-VRF label and the per-CE label, and defines traffic forwarding based on the VRF labels. Upon receiving traffic for the CE that carries the per-VRF label, the first egress node determines the status of the primary path, and forwards the traffic to either the CE over the primary path or to the second egress node, depending on the status.

Methods to improve ECMP for BGP services and BGP for provider edges with hybrid label distribution

Embodiments of the present disclosure relate to methods and systems for on-demand next-hop resolution. Aspects of the embodiments include receiving a triggering event to prompt a request for a path to a network location; requesting a path computation from a second network element based on receiving the triggering event; receiving the path computation from the second network element; and programming an output interface with an indication of the path computation received from the second network element.

On-demand next-hop resolution

A method, apparatus and computer program product for routing data within a packet-switched network using a PW wherein the PW is terminated directly on the layer-3 routing device such that certain services and applications can be utilized is presented. The method, apparatus and computer program product receives an encapsulated layer-2 Protocol Data Unit (PDU) from a pseudowire emulating a service. The encapsulation is removed from the encapsulated layer-2 PDU and a layer-2 circuit associated with the pseudowire is terminated. The circuit is treated as an interface and the PDU is forwarded based on upper layer protocol information within the PDU.
