.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 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
|
