Interconnecting IPv6 networks by carrier supporting carriers method

I have to implement a carrier supporting carriers method for IPv6 clients. I have done it in IPv4, it works perfectly, but it does not work for me in IPv6 ( IPv6 over IPv4 MPLS backbone) and I need someone to help me troobleshuting it. I have attached the project in GNS3, where the routers are configured both for IPv4 and IPv6. In Ipv4 in responds end to end ( between CE1-A and CE2-A): CE2-A#ping [login to view URL] so [login to view URL] Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to [login to view URL], timeout is 2 seconds: Packet sent with a source address of [login to view URL] !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 984/1064/1208 ms CE1-A#ping [login to view URL] so [login to view URL] Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to [login to view URL], timeout is 2 seconds: Packet sent with a source address of [login to view URL] !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 844/1050/1260 ms I need to respond these two in IPv6: CE2-A#ping ipv6 2002:AC10:A00::1 so 2002:AC10:1400::1 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 2002:AC10:A00::1, timeout is 2 seconds: Packet sent with a source address of 2002:AC10:1400::1 ..... Success rate is 0 percent (0/5) CE1-A#ping ipv6 2002:AC10:1400::1 so 2002:AC10:A00::1 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 2002:AC10:1400::1, timeout is 2 seconds: Packet sent with a source address of 2002:AC10:A00::1 ..... Success rate is 0 percent (0/5) As you can see below I received both routes in their routing tables and that makes me think that there is a problem in MPLS with the labels, not in normal IP packets. The clients routers (CE1-A and CE2-A) are receiving the routes through eBGP between CSC-CE1-X-AS2 and CSC-CE2-X-AS2. CE1-A#sh ipv6 route | i 2002:AC10:1400 B 2002:AC10:1400::/48 [20/0] CE2-A#sh ipv6 route | i 2002:AC10:A00 B 2002:AC10:A00::/48 [20/0] Also, I have attached the PDF and some images where you can find this scenario in IPv4, it is very well explained how it works. I am talking about the first scenario CSC Network—Customer Carrier Not Running MPLS. (page 5) After resolving this scenario, I have to do the next scenario from book: CSC Model—Customer Carrier Providing MPLS VPN Service, but also in IPv6. So, if there is someone who can help me first with the first scenario I would be very grateful. Thanks in advance, Anca
