Abstract:

   Neighbor Discovery (ND) is a key protocol of IPv6 first-hop. ND uses
   multicast extensively and trusts all hosts. In some scenarios like
   wireless networks, multicast can be inefficient. In other scenarios
   like public access networks, hosts may not be trustable.
   Consequently, ND has potential issues in various scenarios. The
   issues and the solutions for them are documented in more than 30
   RFCs. It is difficult to keep track of all these issues and
   solutions. Therefore, an overview is useful.

   This document firstly summarizes the known ND issues and
   optimization solutions into a one-stop reference. Analyzing these
   solutions reveals an insight: isolating hosts is effective in
   preventing ND issues. Five isolation methods are proposed and their
   applicability is discussed. Guidelines are described for selecting a
   suitable isolation method based on the deployment scenario. When ND
   issues are prevented with a proper isolation method, the solutions
   for these issues are not needed. This simplifies the IPv6 first-
   hops.
