I finally figured out how to get IPv6 on my outside and inside interfaces of my router (Cisco 2821) and on the uplink port on my switch (Cisco 3750). All three IPv6 addresses are pingable from the outside world. The switch and router are connected with OSPF. I am not able to add the eui-64 prefix to my VLAN. What do I need to do to add IPv6 to my VLANs?
Router interfaces:
interface GigabitEthernet0/0
