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.
This document is a product of the Multiprotocol Label Switching Working Group of the IETF.
