Hi all,

I checked at 7.0-CURRENT release notes, that gre(4) is support IPv6
encapsulation. Could you tell me how I can tunnel IPv6 through gre(4)
? Is anybody ever configure this new thing ?

Referring to man 4 gre :

(1)=09   route add default B
(2)=09   ifconfig greN create
(3)=09   ifconfig greN A D netmask 0xffffffff linkX up
(4)=09   ifconfig greN tunnel A D
(5)=09   route add E D

I only have to configure IPv6 gre address in line (3), am I correct ?

Regards,
