ipsec vti ipv4 over ipv6 possible ?

[nvanhaute]

hi,

I think about switching my VPN backbone ipv4 (vti) in ipv6, but behind all my peers all is in ipv4.

So I would like to start in changing only backbone and not networks behind, is it possible ?

to resume, is it possible to make that :

ipv4 network A ==> Cisco ISR (ipv4 lan inside) | (ipv6 wan outside) <======= ipv6 ipsec vpn (vti)

=======> Cisco ISR (ipv6 wan outside) | (ipv4 lan inside) ==> ipv4 network B

Thanks for your comments.

Best regards

Nicolas

Nicolas,

Can you enable IPV6 unicast-routing on both sides and try again?
