   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 provides advice on the
   implementation of RA-Guard, such that the RA-Guard evasion vectors
   are eliminated.
