Shouldn't be.  In fact there is someone working on it.  I do not know
the status of their work.

Do you want to measure the flows at the LER or the LSR?

I've been getting some "undeliverables" from the mailing list admin account
I'll look to see if you account is one of them.

If you're gonna be at N+I make a trip over to the iLabs and see what we're
doing as part of the Advanced Routing Initiative.  If nothing else stop by
and say hi.

i'm not a kernel hacker but it seems not to be an hard task to put  a 
netfilter hook in mpls....isn't it?

Yes i know this...

>May I ask what you are trying to do?  Maybe I can help point you in the
 right direction.

I'm working on a Diffserv over MPLS trial and i have to implement a system 
which takes some measures on aggregate flows and decides if more provisioning 
is needed (really i'm not sure how to do everything, but now this is not the 
problem...the problem in WHERE); so my idea was to make a netfilter hook but 
now i have to take another way...but the problem is: to intercept a packet at 
any place of the path i have to put a call to my code in that place (i.e. i 
have to hack mpls code) or i can make a module and tell the kernel  (in some 
way) where to plug it in the path (without hacking mpls code)?
At the moment i'm only analysing the code to decide how and where to plug my 
system in the kernel code, after this i can think what it had to do ;-).

Sorry for my bad english i hope all is clear.  

Thank you very much!

Are you asking if there are netfilter hooks in MPLS?  Not, not yet.
As far as I know there are only netfilter hook in the IPv4 and IPv6 code.
Remember there are two differnt path a packet can take to get into the
MPLS code:
-packet arrives at ethernet driver with protocol ID of 0x8847
 (LSR or egress LER)
-packet get diverted from IPv4 into MPLS (ingress LER)

May I ask what you are trying to do?  Maybe I can help point you in the
right direction.

No.  Although it seems you are doing a good job reading the kernel source.
I suggest continuing to do that and ask specific question when you need help.

[mpls-linux-general] packet journey in mpls linux (for experts)

[Francesco O. <f.o...@ti...>]

For my degree thesis i have to understand which is the real path a packet 
traverses in a linux mpls box.
Here is what a know:
when an (e.g.) ethernet frame arrives to the nic, it is stored in a skbuff 
structure; 
here a kernel function dermines the protocol field of the frame and calls the 
code of the corresponding layer; if this code is 0x0800 the frame is passed 
to the IP layer which in turn calls the first netfilter hook (prerouting)...
if the code is 0x8847 the frame is passed to the mpls layer; here are  my 
questions: 
this  means that no netfilter code is called because the frame is handled by 
mpls layer? 
So if i write a kernel module that hooks to the netfilter code, it will be 
bypassed in the mpls core nodes?  
Is there a documentation that explains step by step the funcions that are 
called by the mpls layer?

Thank you very much
Francesco Oppedisano

instruction written in  http://dsmpls.atlantis.rug.ac.be/files/installati=

iproute2-2.4.7-now-ss010824.tar.gz,iptables-1.2.7a.tar.bz2
Have i to follow this advise? What's the difference between packets advis=

Re: [mpls-linux-general] ip route

[Luca Da C. <luc...@ti...>]

Dear e77d

I agree on what Miguel is suggesting  you; 
as James wrote "before running you should learn how to walk". Would be a
good start up for you to get a little bit more into Unix world. You can
find many good books  and tons of docs in the internet covering about
almost every issue; maybe once you get fundamentals you would be less
frustrated and things would work (at least the easiest ones) without too
much effort. Feel free to email me and I'll point you to some documents
(not MPLS for this you have the mailing list and james's help ) 

Cheers,
Luca

Re: [mpls-linux-general] Compiling patched zebra-0.93a problem

[James R. L. <jl...@mi...>]

Hi there,

Are you sure the patch applied cleanly?  Check for the existance of .rej
files.

Second turn off IPv6 via the zebra configure script, it is known that my
patch does not compile with the IPv6 features turned on.

Thanks

Re: [mpls-linux-general] ip route

[Miguel G. <mg...@fi...>]

Dear e77d,
I suggest you to visit The Linux Documentation Project: www.tldp.org
There are lots of HOWTOs and guides that are very useful, you could learn
a lot there. Believe me, it is really worth it, and it seems that you need
some knowledge about Unix. Taking a look at these guides should work for
you.
Cheers,
Miguel.

Re: [mpls-linux-general] php on mpls-linux

[blue c. <nom...@ya...>]

OK, so for the time being, I could setup some 'dumb'
PHP with mplsadm?  Can I do this while mplsd is
running?

thanks

[James R. L. <jl...@mi...>]

There was sthread about this a couple of months back.  You could read
more about it there.

A quick summary.  The formwarding plane can to 'dumb' PHP but the sigalling
plane does not handle it yet.  (ie ldp and rsvp-te need to have
code added to handle it).

[mpls-linux-general] php on mpls-linux

[blue c. <nom...@ya...>]

Hi to all,

Does mpls-linux support penultimate hop popping? 
Here's my config:

port1----linux----port2

I advertise a FEC from port 1 with OSPF and LDP using
label value of 3.  The linux box advertises a label
for that FEC to port2.  When I send traffic from port2
on the label that it received from the linux box, the
packet is forwarded to port1 using label value=3.  I
intend for the linux box to pop the label and forward
unlabeled traffic to port1.  Or, in the case where I
send two labels from port2, I intend for the linux box
to deliver the packet with one label (inner label) to
port1.  Is this possible?

Re: [mpls-linux-general] ip route

[James R. L. <jl...@mi...>]

This solidifies that you have no idea how UNIX works and therefore need
to learn about UNIX before going any further.

Because that is how you apply a diff file.  MPLS is not native to iproute2,
so I have modified it to work with MPLS.  I distribute these changes in the
form or a diff file.

Files that end in 'ps' usually are postscript files.  You need to use
a postscript reader like 'ghostview' to view them.

Did you do a 'make install'? Where did it install 'ip'?  Is that the same
as '/sbin/ip'

While you're at it read the man page for 'which'.

Do you know how to do any sort of debugging?  Do you know how a
Makefile works?  If not, why are you even trying to understand MPLS,
go back to school and learn about UNIX first.

Re: [mpls-linux-general] ip route

[James R. L. <jl...@mi...>]

Does your man page say:

OPTIONS
       For the complete command reference please look at the  following  docu-
       ment:
       /usr/share/doc/iproute-2.4.7/ip-cref.ps

If not, go find that document on the net and read it.
BTW 'scope link' has no relevance to your problem at hand.


Back to your problem at hand:

Why don't you answer all of my questions?  There is a reason I ask
each question, therefore I expect you to answer each one.  Here are
some questions (ie please answer them).

Did you compile and install a MPLS enabled version of iproute2?
If so how, and where did you install it?
(as an FYI 'ip' is part of iproute2)

Does the output of 'which ip' point to the version of 'ip' that you
compiled after patching iproute2?

[mpls-linux-general] ip route

[<e7...@ti...>]

Hi James
I've tryed to do the following
[root@localhost utils]# ip route show
10.0.3.57 via 10.0.3.100 dev eth0  scope link
10.0.3.57 via 10.0.3.100 dev eth0
10.0.3.17 via 10.0.3.100 dev eth0  scope link
!!!Deficit 4, rta_len=3D10
10.0.3.0/24 dev eth0  proto kernel  scope link
127.0.0.0/8 dev lo  scope link
default via 10.0.3.1 dev eth0
What does it mean?What is scope link? I've not found it on man ip
Thanks in advance

Re: [mpls-linux-general] HELP ME PLEASE!!!

[James R. L. <jl...@mi...>]

(CC'ed to the list, please continue to CC the list)

'mplsadm2 -d' toggles kernel debugging.  When kernel debugging is turned
on every mplsadm2 command will result in new info showing up at the end of the
'dmesg' output.

Do you mean mplsadm2 or mplsadm?
What is the output from these commands?

Turn on mpls kernel debugging before issuing these commands then
check the output of 'dmesg'.

Is this your mpls enabled version of 'ip'?
Do a 'which ip' does it point to the version of 'ip' that was built
from the patched version of iproute2?

See above.

Read the 'ip' man page.

pc (10.0.3.100) to another (10.0.3.17)
I've done

 mplsadm -O key1 -o push:gen:16:set:eth0:ipv4:192.168.8.197
 mplsadm -A -I gen:17:0
 mplsadm -L eth0:0
and after i ping 10.0.3.17 from my pc
Like i've told i saw packets going from my pc to the others but i didn't
see MPLS headers.
I've read mails about this problem on this mailing list and i've seen tha=
t
my problem is common to many people but how can i resolve it?
I've another problem:reading mails i've seen that to see thematching betw=
een
labels and device i've to do following commands:
[root@localhost root]# cat /proc/net/mpls*
01010702
[root@localhost root]# ip route show
i've done it and the result is :
[root@localhost root]# cat /proc/net/mpls*

[mpls-linux-general] Help me (my questions are useful for all)

[<e7...@ti...>]

Hi everybody
	i'm trying to use mplsadm, ping and ethereal to set a lsp from my pc (IP=

address 10.0.3.100) to another pc (10.0.3.17), sending to it MPLS packets=

and wiew with ethereal if these packets are MPLS. Yesterday, after i've
read mail "Sorry if i ask again" i've given my pc the same commands
mplsadm -A -O 0
mplsadm  -O key1 -o push:gen:16:set:eth0:ipv4:192.168.8.197
mplsadm -A -I gen:17:0
mplsadm -L eth0:0
After  this ive done ping 10.0.3.17 and wiewing at the other pc that the
packets received from me had header MPLS (i see Label <>unknown  , TTL a
value etc)
Reading better that mail i've given 
ip route add 10.0.3.17 via 10.0.3.100
and it gaves me 
Error: either "to" is duplicate, or "lsp" is a garbage
From  that moment i've read all mails that are in the mailing list about
ip route
I've tryed also to follow indication given to other that have my same pro=
blem
but without any result
I' ve tryed to redownload ip-route2-current.tar.gz, tar it  but without
result
What i've to do?
Another question: how can i resume from the beginning?
Thanks all in advance
