-.Dt GIFCONFIG 8
-.Os
-.Sh NAME
-.Nm gifconfig
-.Nd configure generic IP tunnel
-.\"
-.Sh SYNOPSIS
-.Nm
-.Ar interface
-.Op Ar af
-.Op Ar physsrc physdest
-.Nm
-.Ar interface
-.Ic delete
-.Nm
-.Fl a
-.Sh DESCRIPTION
-The
-.Nm
-utility configures the physical address for the generic IP tunnel
-interface, such as "gif0".
-Argument
-.Ar physsrc
-and
-.Ar physdest
-are interpreted as the outer source/destination address for
-encapsulating IPv4/v6 header.
-Argument
-.Ar af
-specifies the address family for
-.Ar physsrc
-and
-.Ar physdest .
-.Ar af
-can be
-.Li inet
-or
-.Li inet6 ,
-and will be treated as
-.Li inet
-if ommitted.
-.Pp
-If a special argument
-.Ic delete
-is specified,
-.Nm
-just deletes the existing source and destination addresses on
-.Ar interface .
-If no outer addresses are specified, this usage has no effect.
-.Pp
-The
-.Nm
-utility takes the following optional argument:
-.Bl -tag -width Ds
-.It Fl a
-Display information associated with all
-.Xr gif 4
-interfaces.
-.El
-.Pp
-Please note that it is very easy to create infinite routing loop,
-when you configure tunnel over same address family
-(e.g. IPv4-over-IPv4).
-.Pp
-Each
-.Xr gif 4
-interface is created at runtime using interface cloning.
-This is
-most easily done with the
-.Xr ifconfig 8
-.Cm create
-command or using the
-.Va gifconfig_ Ns Aq Ar interface
-variable in
-.Xr rc.conf 5 .
-.Sh EXAMPLES
-If you would like to configure IPv6 over IPv4
-(aka IPv6 in IPv4)
-tunnel between
-.Li 10.1.1.1
-and
-.Li 10.2.3.4 ,
-you should perform the following command:
-.Bd -literal -offset
-# gifconfig gif0 inet 10.1.1.1 10.2.3.4
-.Ed
-.Pp
-.\" To use the
-.\" .Li 0.0.0.0
-.\" feature to establish a tunnel from host1 to host3
-.\" which will encapsulate and carry packets from host2, on host1 do:
-.\" .Bd -literal -offset
-.\" # ifconfig gif0 inet host1  127.0.0.2  # assign an address to gif0
-.\" # gifconfig gif0 inet host1 0.0.0.0    # assign encapsulation addresses
-.\" # route add host2 host3 -ifp gif0:     # encap host2 packets, send to host3
-.\" .Ed
-.\" .Pp
-.\" Note: the
-.\" .Fl ifp
-.\" option to route does not work as documented in
-.\" most versions of FreeBSD.
-.\" .Pp
-.\" On host3 do:
-.\" .Bd -literal -offset
-.\" # ifconfig gif0 inet host3  127.0.0.2  # assign an address to gif0
-.\" # gifconfig gif0 inet host3 0.0.0.0    # assign encapsulation addresses
-.\" .Ed
-.\" .Pp
-.\" Now if you ping host2 from host1, the packets should be encapsulated
-.\" with outer source address = host1 and outer destination address = host3,
-.\" and delivered to host3.
-.\" host3 will decapsulate the packet and deliver it normally to host2.
-.\" .Pp
-This is also possible to use IPv6 as outer proto, by replacing
-.Li inet
-to
-.Li inet6 ,
-and IPv4 addresses to some appropriate IPv6 addresses in above example.
-.Sh RETURN VALUES
-The command exits with exit status of 1 on errors, 0 on success.
-.Sh SEE ALSO
-.Xr gif 4 ,
-.Xr ifconfig 8
-.Sh HISTORY
-The
-.Nm
-utility first appeared in WIDE Hydrangea IPv6 protocol stack kit.
-.Pp
-IPv6 and IPsec support based on the KAME Project (http://www.kame.net/) stack
-was initially integrated into
-.Fx 4.0
