ipv6 newbie question

Hi,

> Is it best practice to have the internet facing BGP router's peering ip (or for that matter any key gateway or security appliance) use a statically configured address or use EUI-64 auto config?

Static. You don't want to have to contact all of your peers when the EUI-64 address changes when you replace hardware.
