            Bug ID: 208173
           Summary: ifconfig gre0/gif0 tunnel inet6
           Product: Base System
           Version: 10.2-RELEASE
          Hardware: Any
                OS: Any
            Status: New

          Reporter: bugs-freebsd-org at bekreyev.ru

Why I can't create GRE-tunnel over IPv6? The same problem with gif interface.

# ifconfig gre0 tunnel inet6 2001:db8::1 2001:db8::2
ifconfig: error in parsing address string: hostname nor servname provided, or
not known

# ifconfig gre0 tunnel 2001:db8::1 2001:db8::2
ifconfig: SIOCSIFPHYADDR: Address family not supported by protocol family

How I can do it?

I found these RFCs:
RFC2473 https://tools.ietf.org/html/rfc2473
RFC7676 https://tools.ietf.org/html/rfc7676
