This same Vendor C wants us to upgrade our 7206VXR's to ASR1K's just so we have the (hopefully working) IPv6 features in IOS-XE that are broken in 12.x.

Finally a useful post in this thread. Good work on the deployment of real ipv6!

Thanks. And thanks to Vendor-C for helping us through it. The IPv6 Broadband featureset on the ASR platform starting from IOS-XR 3.1 is a vast improvement on its predecessors. Biggest hassle with IPv6 in production right now: DNS support is woefully undercooked. I don't think anyone has put anywhere near as much effort into making it fluid, user-friendly, and automated. Simple questions like, "How are reverse mappings supposed to work when you can't predict an end-user's address?" have no good answer. If any systems folks want a nice meaty problem domain to focus their efforts on, DNS would be da shiznit. - mark -- Mark Newton Email: newton@internode.com.au (W) Network Engineer Email: newton@atdot.dotat.org (H) Internode Pty Ltd Desk: +61-8-82282999 "Network Man" - Anagram of "Mark Newton" Mobile: +61-416-202-223
