Chris' config error caused dhcp6c not to configure his downstream interface.

dhclient from ports will only work with the default prefix length assigned by 
the provider. For all providers I have encountered, this is /64 and a good 
choice. But if you want multiple /64's for multiple interfaces, you have to 
request a larger prefix (/56 or /60 depending on the policy of the provider). 
dhclient in ports will not let you do this.

In Chris' case, he only has a single downstream interface (for now) and so 
dhclient in ports would work for that.
