Our configuration is MPLS VPNv6 for IPv6. Therefore we have no native IPv6
in the backbone and no need for OSPFv3.

The IPv4 internet is MPLS VPNv4 so there should be no easy way to attack
our OSPFv2 instance from outside. The attacker is simply not in the same
VRF as the routing protocol.

Is this such an uncommon configuration? I am asking because nobody
mentioned this in the thread.
