	Title           : Routing Loops using ISATAP and 6to4: Problem Statement and Proposed Solutions
	Author(s)       : G. Nakibly

This document is concerned with security vulnerabilities in the
ISATAP and 6to4 tunnels.  These vulnerabilities allow an attacker to
take advantage of inconsistencies between a tunnel's overlay IPv6
routing state and the native IPv6 routing state.  The attacks form
routing loops which can be abused as a vehicle for traffic
amplification to facilitate DoS attacks.  We describe these security
vulnerabilities and the attacks which exploit them.  We further
recommend on solutions to remove the vulnerabilities.
