The case that I think about is when the entity [1] is a function on the
node that I want to monitor separately.  In this case I need to know which
discriminator maps to which function.

Alvaro.


[1]
   o  Entity - a function on a network node that S-BFD mechanism allows
      remote network nodes to perform continuity test to.  An entity can
      be abstract (e.g., reachability) or specific (e.g., IP addresses,
      router-IDs, functions).
