Using Sonera 6rd IPv6 with Cisco IOS router

Sonera recently started offering 6rd tunnels to their customers in Finland. Based on this Comcast example it was easy to get Sonera 6rd up with Cisco 892 running IOS 15.5(1)T.

Config:
ipv6 general-prefix Sonera6RD 6rd Tunnel6
ipv6 unicast-routing
ipv6 cef
!
interface Tunnel6
   description Sonera 6RD IPv6 tunnel
   no ip address
   no ip redirects
   ipv6 enable
   tunnel source Gigabit0
   tunnel mode ipv6ip 6rd
   tunnel 6rd prefix 2001:2003::/32
   tunnel 6rd br 80.221.111.254
!
interface Vlan1
   description Inside
   ipv6 address Sonera6RD ::/64 eui-64
   ipv6 enable
   no autostate
!
ipv6 route ::/0 Tunnel6 2001:2003:50DD:6FFE::
