SLAAC with OSPFv3 simulation. I can TFTP with IPv6 to my Ubuntu server. This simulation shows SLAAC with IPv4 and IPv6 and does a IP DHCP Helper on iosv6 for iosv7. I did OSPFv3 because of the number of ip routes without a protocol that would have been needed. Without a protocol like OSPFv3, I would need to create IP routes for IPv4 and IPv6 in both directions.
