Ballot Text

Technical Summary

   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 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 requests that the remote BFD peer
   transmits BFD control packets over the specified LSP.
