As I put into the doc, I don't think that's quite right. If both the source and dest ULAs are in the same /48 then I think the correct default is as you say (use ULA). If the source and dest ULAs are in different /48's then I think the correct default is instead to use the non-ULA global, since there's no guarantee of routability between different /48s. So unless configured otherwise, one has to assume it's far more problematic than a non-ULA global. You'll find the above logic in the current 3484bis draft. -Dave -------------------------------------------------------------------- IETF IPv6 working group mailing list [email protected] Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
