Abstract

See full text

Systems and methods for enabling Bidirectional Forwarding Detection (BFD) over a selected reverse path are provided. A process, according to one implementation, include sending an echo request in a forward direction from an initiator node to a reflector node. For example, the initiator node and reflector node may be configured to operate in a network having no or different centralized controller that manages both the initiator node and reflector node. The echo request may be sent to the reflector node to discover a reverse path in a reverse direction from the reflector node to the initiator node. Also, the reverse path is discovered for the purpose of initiating a Bidirectional Forwarding Detection (BFD) or Multi-Protocol Label Switching (MPLS) Ping procedure.
