James -

Lars and Pekka are reporting external issues with our IPv6 announcements, and Lars is on-site.

I spoke with Lars this morning and explained that one of our providers is unwilling to accept the /32 and want multiple smaller blocks, and that the funet folks want ONLY the /32. Unfortunately a bit of an impasse.

I'll leave the ticket open in case James/Leon? wants to push on the local provider to consider accepting the /32.

Replying to jim@…:

I spoke with Lars this morning and explained that one of our providers is unwilling to accept the /32 and want multiple smaller blocks, and that the funet folks want ONLY the /32. Unfortunately a bit of an impasse.

I'll leave the ticket open in case James/Leon? wants to push on the local provider to consider accepting the /32.

well, it will be quite difficult because it is not our direct provider who refuses accept /32, but one of the providers of our provider. When it is more than one hop away, our influences are really limited... we will see what we could do about this situation.

thanks,
Leon

I advertised 2001:df8::/32 to CERNET and CSTNET for this issue, but this prefix could not pass the AS18344, so the CERNET is only one path to reach the fit.nokia.com (2001:708:40:fff1::1).
