|
|
.Sh NAME
|
|
.Nm greconfig
|
|
.Nd set characteristics of the
|
|
.Xr gre 4
|
|
pseudo device.
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Fl i Ar unit
|
|
.Op Fl v
|
|
.Nm ""
|
|
.Fl i Ar unit
|
|
.Op Fl d Ar dst

.Op Fl s Ar src

.Op Fl p Ar proto
|
|
.Op Fl v
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
is used to manipulate or display the characteristics of the
|
|
.Xr gre 4
|
|
tunnel device. The first form shown above displays the current
|
|
parameters, while the second one sets parameters to new values.
|
|
.Pp
|
|
The options have the following meanings:
|
|
.Bl -tag -width flag
|
|
.It Fl i Ar unit
|
|
Denotes the interface that is to be set/displayed. Unit is in the form
|
|
.Dq greN
|
|
where N is an integer from zero to the maximum numbers of
|
|
units. This option is always required.
|
|
.It Fl d Ar dst
|
|
Sets the IP address of the remote tunnel end. This may be the same as the
|
|
tunnel destination set with
|
|
.Xr ifconfig
|
|
when IP packets are to be encapsulated.
|
|
.It Fl s Ar src
|
|
Sets the IP address of the local tunnel end. This may be the same as
|
|
the tunnel gateway set with
|
|
.Xr ifconfig
|
|
when IP packets are to be encapsulated.
|
|
.It Fl p Ar proto
|
|
Sets the way how packets are encapsulated. Currently supported values are:
|
|
.Bl -tag -width aaa
|
|
.It 47 GRE encapsulation as described in RFC 1701,1702
|
|
.It 55 MOBILE encapsulation as described in RFC 2004
|
|
.El
|
|
.It Fl v
|
|
Give a little more verbose output when running
|
|
.Nm Ns .
|
|
.El
|
|
.Pp
|
|
Note that the values for
|
|
.Ar src ,
|
|
.Ar dst ,
|
|
.Ar proto
|
|
must be coordinated with the remote end of the tunnel.
|
|
.Pp
|
|
For tunnels that run IP as encapsulated protocol, the tunnel endpoints
|
|
can be set with the normal
|
|
.Xr ifconfig .
|
|
In this case, the encapsulation protocol can be chosen by giving
|
|
.Dq link0
|
|
for IPIP encapsulation and
|
|
.Dq -link0
|
|
GRE encapsulation
|
|
as arguments to
|
|
.Xr ifconfig .

A description of GRE encapsulation can be found in RFC 1701, RFC 1702.

|
|
A description of MOBILE encapsulation can be found in RFC 2004.
