I am not sure what kind of answer you would expect. BIRD (AFAIK)
supports announcing IPv6 over IPv4 connection, but it is not a suggested
configuration. Because if bird6 is listening also on IPv4 socket, you
cannot start bird4 on the same address/iface. And also it can forward
IPv6 routes even if IPv6 is not really working on the router.
