Configurable policy in version 2.5, and Teredo in the default policy only very recently. Because Teredo is not mentioned in RFC3484, I expect many other RFC3484 implementations do have the same issue. Unfortunately, even if they don't have Teredo support themselves, they should still recognize the prefix for source address selection... I did write an I-D to allocate one new prefix, but then I realized that the revised RFC3484 draft work already mentioned it, so I did not bother submitting it. In your particular case, did you try to add label 2001:0::/32 7 precedence 2001:0::/32 5 to /etc/gai.conf ? -- Rémi Denis-Courmont _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
