Hi, > That’s a bit of a snarky question, but it’s a real one. Is there any > real-world problem for which 6rd is the best answer? The deployments that I worked on used 6rd because the L2 infrastructure couldn't do first-hop security for IPv6. No DHCPv6-PD snooping, no source guard etc. They refused to deploy IPv6 in a much less secure way than they deployed IPv4. And of course the switches either couldn't be software upgraded or would require newer supervisors to support the features they needed. Part of that has solved itself over the years with forklift upgrades, but not everywhere. So they couldn't do native IPv6, but still wanted to provide IPv6 service to their users: hence 6rd. Cheers, Sander
