1.  Introduction

   The Neighborhood Discovery Protocol (NHDP) [RFC6130] allows routers
   to acquire topological information up to two hops away from
   themselves, by way of periodic HELLO message exchanges.  The
   information acquired by NHDP is used by other protocols, such as
   OLSRv2 [OLSRv2] and SMF [SMF].  The topology information, acquired by
