yes, sure, it was some time ago that the discussion happened :(
6rd can be poorly done by embedding the entire IPv4 address in the IPv6 address. Doing that does waste space. 6rd deployment should not require much more IPv6 /48’s than a native IPv6 deployment would. That does require properly configuring your DHCPv4 servers with DIFFERENT 6rd DHCPv4 Option values on a per IPv4 DHCP pool basis which I’m sure every ISP here is capable of doing as there is nothing really new here to do. You have all carved up IPv4 assignments into IPv4 pools. This is no different. You carve up a IPv6 assignments into similar sized pools of /48’s then set the 6rd DHCPv4 Option to the appropriate values for that IPv4 to IPv6 pool mapping. Add the mapping to the BRs and you are done. Mark -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: marka () isc org
