Singhh,
1. Yes, I can see remote CE route in VPNv4 table.
2. No. Those are local prefixes including the link local prefixes.
3. I have configured the ipv6-tunneling on both PEs under the MPLS proto but still those routes are not redistributed into ospfv3 domain. Also, the PE-CE is enabled for both v6 and v4.
I have also attached both PE configurations.
NB: The current configurations works perfectly well with OSPFv2 and the current requirement is using OSPFv3 to route IPv4 traffic.
Thanks for your help so far mate.
