We've had good success with both GRE (insecure) and OpenVPN over UDP.
In both cases, it's pretty trivial:

  - start the tunnel;
  - make sure the tunnel endpoints have link-local IPv6 addresses;
  - assign IPv4 addresses to the tunnel endpoints;
  - run babeld with

       interface tun0 type tunnel
