Very important Cisco command

ipv6 unicast-routing

I'm noticing a number of Cisco users that try to use their routed /64 or /48 on an interface, and can't seem to get connectivity to their LAN hosts.

Added a note about that to the IOS example configuration.

no ipv6 source-route
ipv6 cef

Although not strictly required these are also very useful and should be on every IPv6 enabled internet facing IOS router in my opinion.

Using IPv6 CEF breaks IPv6 via PPTP (1811 15.1(2)T)
