Establishing a IPv6 tunnel to Tunnelbroker. Its in the router config guide, but as usual the docs do not make any sense.
Anyone have a config for a Tunnel. Its trivial in Cisco!

Here's a config that worked for me 5 years ago when I last used it.
All that is required on the ALU is this line of config (with appropriate prefix filled in)
static-route <cust-ipv6-prefix::/length> indirect <ipv4 address of ipv6ip tunnel end point>
Optional: Can also have this line of config to match the tunnel config on the cisco end
static-route 2001:DB0:DD0:CC0D::1/128 indirect <ipv4 address of ipv6ip tunnel end point>
The Cisco side does need an IPv6 address to be configured on the tunnel
!
interface Tunnel1
description IPv6 tunnel test
no ip address
ipv6 address 2001:DB0:DD0:CC0D::1/64
tunnel source GigabitEthernet0/1 <--- IP of this is the target of indirect on the ALU
tunnel destination 172.16.0.12
tunnel mode ipv6ip
end
ipv6 route ::/0 Tunnel1
