Title : Routing Loops using ISATAP and 6to4: Problem Statement and Proposed Solutions
Author(s) : G. Nakibly
Filename : draft-nakibly-v6ops-tunnel-loops-01.txt
Pages : 13
Date : 2010-02-01
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.
