Renato,

I appreciate all you have done for this project since James started 
looking for people to hand off to.  I was aware of his request for help, 
but I never knew what the results were, so this organizational structure 
is news.

I would very much like to get this project integrated into its various 
upstreams including the kernel, and also get the Quagga LDP code 
integrated over there too.

I'd like to offer help documenting the mpls-linux part, I can easily put 
together a small lab to test interop with cisco and Juniper once we get 
some repositories that build, or even a current set of patches if that's 
the best place to start.

	Sorry, I've been really short of time. I am still interested and have done some
more cleanups in the code in this time. But I am not really interested in
maintaining patches for an outdated kernel because I think that we should aim
for kernel inclusion.
	So, if you can add me to the project and I can clone kernel git and work from
there, I can push a topic branch with my cleanups this same week.

@Milos Vujkovic

I also recommend you to start with the MPLS Labs from Adrian Popa. The
only problem is that the kernel and tools used in those experiments
are a bit old. If you want you may use that documentation but use the
lastest MPLS code from Sourceforge (kernel 2.6.32 instead of kernel
2.6.15). The commands are the same and the MPLS Labs scripts should
work.

You can grab the lastest MPLS code with this command:
git clone git://mpls-linux.git.sourceforge.net/gitroot/mpls-linux/mpls-linux

Compile & install instructions (no rpms sorry ^^):

@Scott Whyte

I have to agree that the mpls-linux project is a disaster in terms of
organization. The wiki is outdated and this mailing list is almost
dead.

The problem IMHO is the lack of contributors. When James decided to
retire from the project I have offered myself to maintain the
Quagga/MPLS integration and work in the LDP support. Some other people
were named to maintain the kernel and the documentation. Since then
the Quagga/MPLS integration got working and the LDP reached an usable
state, working OK when acting in an ingress LSR. Now I'm working to
port the OpenBSD LDP to Quagga/Linux.

Since the others maintainers gone quiet, I ported myself the MPLS code
to the newer versions of the upstream projects: iproute2-2.6.35,
iptables-1.4.10, linux-2.6.32.27. I also ported the MPLS code to the
kernel 2.6.35, which is the version that I'm currently using. However
I'm not a kernel developer, this project needs a real kernel developer
to keep improving the MPLS stack in the kernel.

(sorry for my english)

Hey all,

It is good to see discussions occurring.  Last year about this
time I made a plea for someone to step up and start maintaining the
project.  I had 3 people that started out very interested, but they've
gone quiet.  I'll be more then happy to help someone else start organizing
the git repo or answer questions on the code.

Its true that the OpenLSR project hosted on code.google.com is a system
integration project done by a very capable summer intern I had.  Its
also true that I would love to be moving it forward onto current (x64)
kernel and quagga versions, but it seems the mpls-linux project
organization is in so much disarray that other OSes start to look more
interesting.  In particular OpenBSD has support for LDP in their kernel.

I'm very glad to hear that the code, including verilog, is found useful
by some.  I'm actively working on better MPLS support in the NetFPGA
platform, if we could get mpls-linux a bit more organized with respect
to the code repository, I'm certain I could keep NetFPGA verilog updates
coming, in the interests of network research.

Dear Adrian and Marton,

Thank you for your prompt help, I greatly appreciate it. I will give my best
to make it running, and report my results here.

Thanks again,

Re: [mpls-linux-general] Setting up simple lab - how?

[Steierlein M. <st...@gm...>]

No, this is just a project hosted on Google code. Some students made
major strides from the mpls-linux project, including a a hardware MPLS
switch. The source code in verilog is even accessible. Such knowledge
and codebase is priceless.

Well, if google has started to work with mpls-linux I think it will breathe

Re: [mpls-linux-general] Setting up simple lab - how?

[Steierlein M. <st...@gm...>]

Milos,

Try this:

http://www.nanog.org/meetings/nanog50/presentations/Monday/NANOG50.Talk17.swhyte_Opensource_LSR_Presentation.pdf

There is a URL at the end of the slides. Follow the steps in the
readme and disable sysctl table in the kernel. I also managed to
install it on two debian systems.

Unfortunately the sources are not up-to-date and the patch is a pain
in the ass as well.

If you need any help feel free to post your questions.

Re: [mpls-linux-general] Setting up simple lab - how?

[Adrian P. <adr...@gm...>]

Hello Milos,

If you want something simple, look here:
http://sourceforge.net/apps/mediawiki/mpls-linux/index.php?title=Examples

If you want something a bit more complicated, look here:
http://downloads.sourceforge.net/project/mpls-linux/mpls-linux/MPLS%20Linux%20Labs/mpls-linux-docs_v1.950.tar.gzand
download
http://downloads.sourceforge.net/mpls-linux/mpls-linux-labs_v1.950.tar.gz

There are some tips in the instructions above on how to install mpls support
on debian, but you will need to run a supported kernel.

Good luck,
Adrian

Hello everyone,

I am trying to give mpls-linux a test run in my VmWare lab. What I would
like to have running is this simple scenario:

host1 -- router1 -- router2 -- host2 ,

where all nodes are Linux virtual machines, running Debian. However, I am
having hard time finding any kind of documentation, support or instructions
on how to perform this. Can someone point me to relevant place where I could
get more help with this?

Thank you in advance,

[mpls-linux-general] Mpls linux status ?

[Sébastien C. <scr...@gm...>]

Hello,

I would like to know what is the current mpls-linux project status  ?

Seems that the git repositories are not available ???
I've found in this list a patch for 2.6.35 kernel but nothing about quagga
patch ...

We have just jump into Vyatta systems. Vyatta doesn't support Mpls and Vrf !
We would

Let me know where can I download all necesary source code.

Thank you

[mpls-linux-general] [mpls-general]MPLS error

[Steierlein M. <st...@gm...>]

Dear Developers,

I have succesfully compiled the MPLS support in the Linux kernel,
compiled and installed iproute and iptables, quagga with ldp support
as well.

Topology is as follows:

<eth0:192.168.0.198>[Excelsior]<eth1:172.16.0.2> --------
MPLS---------<eth1:172.16.0.1>[Constitution]<eth0:192.168.5.50>

Excelsior has a loopback address (dummy0) of 10.10.10.2 and
Constituion has a 10.10.10.1. OSPF works, ping succeeds.

Pinging from Excelsior to Constitutio (from 192.* addresses) fails.
Catting syslog tells the following:

The ip addresses on dummy0, Excelsior are a result of ospf not being
able to distribute routes to /32 addresses. I had to experiment, the
10.10.10.20 is completely unnececessary. Unfortunately router id-s are
not these addresses as Excelsior has OpenVPN installed and there is a
tun0 interface with 10.0.0.1.

Any help would be very much appreciated. Thanks!

Re: [mpls-linux-general] Hello

[Dibyajyoti G. <dj....@gm...>]

Hi Nilesh,
 Linux : Debian 5 with 2.6.26-1-686 kernel.
 Then download and install linux-2.6.25.14 with mpls-1.962 patch. download
1.962 patch from
http://repo.or.cz/w/mpls-linux.git/snapshot/131b65b4fdc79d30b75d351d3e4bc155da932548.tar.gz.

Here is my dmesg output :
parul:/usr/src/mpls-linux# dmesg | grep MPLS
[    0.852242] MPLS: version 1.962
[    0.852296] MPLS: protocol driver interface - <jl...@mi...>
[    0.852758] MPLS: IPv4 over MPLS support

parul:/usr/src/mpls-linux# uname -a
Linux parul 2.6.25.14 #1 SMP Mon Oct 25 17:48:57 EDT 2010 i686 GNU/Linux
parul:/usr/src/mpls-linux#

I took RPM packages from
http://mpls-linux.sourceforge.net/fedora/10/i386/mpls/

then use alien to convert
iproute-2.6.27-2.fc10.mpls.1.963.i386.rpm<http://mpls-linux.sourceforge.net/fedora/10/i386/mpls/iproute-2.6.27-2.fc10.mpls.1.963.i386.rpm>into
.deb. After installing using dpkg, I am able to get mpls CLI working.

Although above RPM (mpls built into)are made for Fedora 10. For Debian you
need to get iproute-2.6.27.tar.gz and then apply iproute patch diff file
from mpls-1.962 patches. Then run gcc to make iproute patch with mpls. So I
have given the work around to use RPM after converting using alien.
Hope this should work.

install mplsLinux on Fedora machine.
I have some questions.

1. What are the OS requirements (fedora version/kernel)?
2. what are the hardware requirements?
3. Does Logical Volume Management ( LVM ) affect mpls linux

Can anybody help?

Control (ARC), sliding windows and start stop to flow control in mpls sir??
 i use mpls-linux in fedora core 5 operating system (mpls-linux-1.955).. and 
have you script about these flow control... and then is that flow control can 
control sum of traffic or what?? i still don't understand if  it make real in

I'm interested in using MPLS for a project I'm currently developing.

http://sourceforge.net/mailarchive/forum.php?thread_name=g2r64ecee491004130227la3229248y109d3f04f1b4fe13%40mail.gmail.com&forum_name=mpls-linux-general 
<http://sourceforge.net/mailarchive/forum.php?thread_name=g2r64ecee491004130227la3229248y109d3f04f1b4fe13%40mail.gmail.com&forum_name=mpls-linux-general>

Do you have any suggestions on how to solve this problem? Any help would 
be very appreciated.

By the way, is there any chance of using a more recent kernel version? 
If so, which kernel version should I use and where can I get the patch 
for it?

Thank you for your time,
Daniel Figueira

Re: [mpls-linux-general] Error message when establishing LSP between two routers

[Jonathan E. <ell...@go...>]

Still new to MPLS linux, but I had this problem before and I fixed it by
loading all of the MPLS kernel modules that were built in the
mpls-linux/src/ directory:

insmod mpls.ko
insmod mpls4.ko
insmod mpls6.ko
insmod ebt_mpls.ko
insmod mplsbr.ko
insmod mpls_tunnel.ko
insmod xt_mpls.ko

Hope that helps

Jonathan

[mpls-linux-general] problem witth testing mpls and MTU=0

[lili l. <lit...@gm...>]

Hi,

I need help for my linux-mpls tesbed.
I success to configure my testbed like the one in "sourceforge - example"
But if I test with a ping command, it does not work.
In addition I have the following output after executing  "*mpls nhlfe add
key 0 instructions push gen 1000 nexthop eth2 ipv4 .... *"
*
NHLFE entry key 0x00000002 mtu 0 propagate_ttl
     (0 bytes, 0 pkts)*

Is it normal to have MTU=0?

Thanks for helping me.
