Xiao,

Scanning through the draft, two questions:

1. What is the underlying mechanism to check liveness such that Demand can be used?

https://tools.ietf.org/html/rfc5880#section-6.6

   Demand mode requires that some other mechanism is used to imply
   continuing connectivity between the two systems.  The mechanism used


2. Is this draft testing liveness of a path or a node?

https://tools.ietf.org/html/draft-mirsky-bfd-mpls-demand-03#section-3

   In this state BFD peers MAY remain as long as the egress LER is in Up
   state.  The ingress LER MAY check liveness of the egress LER by
   setting the Poll flag.  The egress LER will respond by transmitting


Thanks,

— Carlos Pignataro

I support WG adoption of this draft. Use of the demand mode for p2p LSP monitoring is feasible and required.
