For my CCIE SP training I've been working on basic L3VPN's over MPLS with OSPF as an IGP, happy with the way that works. So have moved onto something a little more ambitious, with an IPv6 only PE-P links and isis, to support IPv4 and and IPv6 L3VPN's. As I understand it this is 6VPN?
The ipv6 and isis apears to be working fine, from my PE loopback used to anchor BGP and LDP I can ping the remote PE loopback IPv6 address across my core, using my loopback as a source. The BGP session is active, but not passing any ipv4 routes, and I'm struggling to see where I'm going wrong, not totally sure what troubleshooting commands to look at. I'm just trying to advertise a loopback on the PE into the vrf TEST, which worked fine on my IPv4 MPLS lab. All the MPLS LDP seems ok.
My goal is to have seperate L3VPN's to carry ipv4 and ipv6 traffic across the ipv6 core, but so far I've been unable to find an example. This is using GNS3 7200 emulation, with 12.2(33)SRE7 SPSERVICES code.

How should I troubleshoot this, I'm out of ideas, and unfamilar with the IPv6 and ISIS element of this, although at this stage I'm sure that is working ok, and that the issue is with the MP-BGP configuration somewhere.
