Why do you say you cannot run a routing p...Hi Jeff,<br />Why do you say you cannot run a routing protocol with ISATAP? You can. I find that really one of the strengths of ISATAP. The IPv4 number is not in the network part of the IPv6 address (which is the case with automatic 6to4.) Therefore you're not bound to a specific IPv6 addressing scheme with ISATAP for your client networks. All Tunnels connect in the same subnet at the IPv4 border and that is where you run OSPFv3. So in the end all IPv6 networks are advertised across the IPv4 network. To me that ISATAP is the clear winner ;)rinmeisterhttps://www.blogger.com/profile/00120511755110391714noreply@blogger.com
