There's a cisco doc somewhere but here's a sample config from our routers:

interface Tunnel2
  description 6to4 Tunnel
  ipv6 unnumbered Loopback2
  tunnel source Loopback2
  tunnel mode ipv6ip 6to4

interface Loopback2
  description 6to4 relay anycast address (RFC 3068)
  ip address 192.88.99.1 255.255.255.0
  ip pim sparse-mode
  ip igmp version 3
  ipv6 address 2002:C058:6301::/128
  ipv6 enable

ipv6 route 2002::/16 Tunnel2


Good luck!
