While more succinct, the implication is fail-open without policy.  (Shades
of the subtleties that got us RFC 8212.)

Perhaps instead:
"..., when permitted by local configuration or policy, the passive side
SHOULD create a matching BFD session toward the active side" ?

<RR> I am good with this change, Jeff thanks for the suggestion.
Regards,Reshad.
