consider the following document:
- 'Implementation Advice for IPv6 Router Advertisement Guard (RA-Guard)'
  <draft-ietf-v6ops-ra-guard-implementation-04.txt> as Best Current
Practice

The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the

Abstract


   The IPv6 Router Advertisement Guard (RA-Guard) mechanism is commonly
   employed to mitigate attack vectors based on forged ICMPv6 Router
   Advertisement messages.  Many existing IPv6 deployments rely on RA-
   Guard as the first line of defense against the aforementioned attack
   vectors.  However, some implementations of RA-Guard have been found
   to be prone to circumvention by employing IPv6 Extension Headers.
   This document describes the evasion techniques that affect the
   aforementioned implementations, and formally updates RFC 6105, such
   that the aforementioned RA-Guard evasion vectors are eliminated.
