v6ops I published 04,add some comments. 4.2. Configuration 4.4. Traffic Pattern http://tools.ietf.org/html/draft-sakura-6rd-datacenter-04
I believe native IPv6 data center is ideal,but the operators sometimes can not reach the ideal. Server based 6rd would be useful to provide IPv6 to customer as solution. Could you share presentation time slot in IETF83?
