|
||||
A GRE Tunnel for NetBSD
|
||||
|
||||
Heiko W.Rupp
|
||||
<hwr@pilhuhn.de>
|
||||
|
||||
This is a very alpha implementation of GRE packet encapsulation.
|
||||
Generic Route Encapsulation (GRE) is described in RFC 1701 and 1702.
|
||||
The interface also supports MOBILE (protocol 55) as of RFC 2004 but
|
||||
default is GRE mode.
|
||||
|
||||
Basically GRE allows to tunnel not only IP over IP, but also provides
|
||||
for other protocols like Appletalk etc. Cisco routers do their multicast
|
||||
tunnels over GRE (1). The hope is, that with GRE encapsulation, a method
|
||||
is found to encapsulate all other protocols with one mechanism and reduce
|
||||
the need for own tunneling in ip_mroute etc.
|
||||
|
||||
This implementation is (as said) still alpha, but works for me.
|
||||
Successful testing has been done for GRE encapsulation with Cisco routers
|
||||
and NetBSD boxes as remote.
|
||||
|
||||
The files:
|
||||
|
||||
net/if_gre.[ch] : output interface, encapsulates packets.
|
||||
netinet/ip_gre.[ch]: input part, deencapsulates packets. Is IP only
|
||||
at the moment and only supports GRE without options.
|
||||
netinet/in.h : Addition of IPPROTO_GRE
|
||||
netinet/in_proto.c : Addition of protocol switch for GRE
|
||||
conf/files : mention new files for GRE
|
||||
greconfig.c : Utility to set/display tunnel endpoints / mode.
|
||||
greconfig.8 : Manpage for greconfig.
|
||||
gre.4 : Documentation of driver plus example.
|
||||
|
||||
|
||||
Installation:
|
||||
|
||||
On NetBSD: add "pseudo-device gre <n>"
|
||||
to your kernel config file with <n> being the number of tunnel interfaces
|
||||
you want. Then recompile and install the new kernel.
|
||||
|
||||
Also compile greconfig.c: cc -o greconfig greconfig.c
|
||||
Grectl is used to set/display tunnel endpoints. In case when IP is
|
||||
encapsulated, this is not needed, but e.g. in the AppleTalk over IP
|
||||
case.
|
||||
|
||||
Todos/Bugs:
|
||||
Support other protocols for encapsulation
|
||||
|
||||
The compute_route() code in if_gre.c toggles the last bit of the
|
||||
IP-address to provoke the search for a less specific route than the
|
||||
one directly over the tunnel to prevent loops. This is possibly not
|
||||
the best solution.
|
||||
|
||||
GRE RFC not yet fully implemented (no GRE options), no other protocols
|
||||
yet than IP over IP.
|
||||
|
||||
Code quality is surely not best and possibly not near anything like KNF
|
||||
|
||||
Traceroute does not work yet over the tunnel :(
|
||||
|
||||
BPF does probably not yet work (it might, but last time I looked,
|
||||
it bombed, so I #if 0'd it out). And also only in outgoing
|
||||
direction.
|
||||
|
||||
---------------------------------------------------------------------------
|
||||
|
||||
(1) tunnels that end on a mrouted have tunnel mode DVMRP set

|
||||

|

.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 8
|
||||
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 8
|
||||
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 8 .
|
||||
In this case, the encapsulation protocol can be chosen by giving
|
||||
.Dq -link0
|
||||
for GRE encapsulation
|
||||
as argument to
|
||||
.Xr ifconfig 8 .

||||

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

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