Hi Folks Just a quick heads up - yesterday on Citylink we had the customer of an ISP perform a very effective DOS on that ISP when the customer put the IP number of the ISP's router on to the Citylink interface of their own router. Any ISP who has a Cisco router attached to a public L2 infrastructure (such as Citylink) really needs to read the Cisco advisory: http://www.cisco.com/warp/public/707/IOS-arp-overwrite-vuln-pub.shtml and take the appropiate precautions.
