IPv4 is working file over psedowire using MPLS or L2TPV3. But, I am facing problem with IPv6.
If both site is PPP or both site is Frame-relay, I could setup IPv6 over pseudowire. But, if one site is PPP and another site is Frame-relay, I could not setup IPv6 over Pseudowire. I have to use 'interworking ip' for the pseudowire. Without that, IPv4 doesn't work. But, with 'interworking ip', IPv6 at PPP site never up.
Is there any solution to solve this issue? I hope this will not be exam question.
