See above for my test configuration. What I am trying to do is set the VSA's in RADIUS for both the unnumbered loopback interface and the VRF. The IPv4 address and IPv6 prefix should be delegated from the local pools. I will post additional troubleshooting output later but in the meantime can someone look at this and verify there isn't something here in the BNG config that would cause the session not to come up? I see authentication passing in RADIUS and it is handing the VSAs back to the BNG but the IP is not allocated in the BNG.  Xander?
