Folks, We have posted on the SI6 Networks blog more information about IPv6 RA-Guard evasion, including pointers to the recent presentations at IETF 81. The post is available at: http://blog.si6networks.com/2011/09/router-advertisement-guard-ra-guard.html P.S.: In case you haven't, you may want to join the IPv6 Hackers mailing-list: http://www.si6networks.com/community/mailing-lists.html Thanks!
