I get authenticated with PEAP MSCHAPv2, but no IP address. After 20 seconds I only get a self assigned: spock# ifconfig en1 en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500

Hi, I'm at the far end of the hackathon, at the table with switch SW-HACK5. I have a router wired in, which is expecting to see DHCPv6-PD. It sees IPv6, but not apparently DHCPv6. Surprisingly, it has an rfc1918 IPv4.

I heard that there might have been DHCPv6PD issues. In the meantime, I have a solution that I use in other less cool venues.

Not seeing ietf-a, ietf-a.1x in Emerald
