GRE over IPv6 configuration

[Affan Basalamah]

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

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

Regards,
