Bidirectional Forwarding Detection Reverse Path for MPLS Label Switched Paths
RFC 9612, “Bidirectional Forwarding Detection Reverse Path for MPLS Label Switched Paths”, is an Experimental document published in July 2024 by G. Mirsky, J. Tantsura, I. Varlashkin, M. Chen. The canonical text is published by the RFC Editor.
Abstract
Bidirectional Forwarding Detection (BFD) is expected to be able to monitor a wide variety of encapsulations of paths between systems. When a BFD session monitors an explicitly routed unidirectional path, there may be a need to direct the egress BFD peer to use a specific path for the reverse direction of the BFD session. This document describes an extension to the MPLS Label Switched Path (LSP) echo request that allows a BFD system to request that the remote BFD peer transmit BFD control packets over the specified LSP.
What “Experimental” means
Describes a specification that is part of a research or development effort, published so the community can gain experience with it.
