[O. <aol...@av...>]

I found something wrong with my kernel... the 
CONFIG_IP_MPLS was deactivated! 
I'll try it now

Re: [mpls-linux-general] MPLS-Linux example problem

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

Make sure you've loaded the mpls4 module:

    modprobe mpls4

(by default all ILMs are bound to IPv4 as the upper layer protocol.  You
can override this behavior using the 'protocol' parameter)

Re: [mpls-linux-general] MPLS-Linux example problem

[O. <aol...@av...>]

Hi again!

I'm trying the solution you gave me ( the IPv4 over MPLS: two LER
example for mpls-linux-1.950 one )and I'm getting some problems in LER2:

uml2:~# mpls ilm add label gen 1000 labelspace 0
RTNETLINK answers: Cannot allocate memory

dmesg shows:


MPLS DEBUG net/mpls/mpls_netlink.c:115:genl_mpls_ilm_new: enter

Any ideas?

[O. <aol...@av...>]

Yes, I'm using version 1.950. I'll try the examples pointed by you.

Thank you!

Re: [mpls-linux-general] ldpd doesn't start properly

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

It is mostly implemented, which just bugs to fix.  I'm sure there are
plenty of though.  Last week I started working on it again, so additional
testing, bug reports are exactly what I'm looking for.  Although I need the
bug reports to contain more debugging info.

If you are interesting in helping me hunt bugs/do testing, then you should
get the latest quagga-mpls and ld-portable from the perforce server.
This way you will be able to update your tree and rebuild RPMs for
more testing.

I think the instuctions for the accesing the perforce server at
http://mpls-linux.sf.net are still update date.  Give them a try
and let me know if you hit any snags.

Re: [mpls-linux-general] ldpd doesn't start properly

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

Ok. Thank you for message.

I hadn't realized that ldpd wasn't ready for users.

I'd like to help out, but I don't have a lot of experience in C, or
the linux network architecture.

If there is a way I can help, please let me know. For now, I'll keep
sending bug reports :)

The thing is that I kind of relied on ldpd working so I can set up
experiments for my graduation diploma.

I'd like to ask you at what stage has the development of ldp arrived?
Is it mostly done, with bugs to clear? Or is it somewhere in the
middle of development? If it's the first case, I'd like to help you
(as best I can) to isolate and correct any bugs.  If there's a lot of
work to be done, I'm sorry, I'd like to help, but I'm afraid I'm
pressed by the lack of time.

Are you close to releasing a new version of ldp? (Could it be done in
less than 1.5 months?) If yes, I'm eager to help. If not, then the
result could arrive to late to help me.

I hope my reply hasn't brought you down. I'll keep trying to use ldpd
(I'm not out of ideas yet), but I'd like to ask you two more
questions:

1. Has this version of ldpd worked on a given test-bed? (Has it done
what it was supposed to do?)
2. Do you have some more elaborate configuration files for ldpd for
the test-bed it worked on? (So that at least, I have somewhere to
start from).

Thank you kindly for your time

Re: [mpls-linux-general] MPLS-Linux example problem

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

I'm not sure if this helps, but try to issue a

cat /sys/mpls/version

and see what it says. If it says 1.950 (or newer), than the examples
in http://mpls-linux.sourceforge.net/simple.php are no longer valid.
For examples (for version 1.950) see this link:

http://sourceforge.net/docman/?group_id=3D15443

Hope it works out for you.

Re: [mpls-linux-general] ldpd doesn't start properly

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

Not unexpected.  If you look back in the archives you'll see that I do not
consider ldpd ready for users.  If you are a developer, and want to help fix
it, I'll be more then happy to provide pointers.

Otherwise wait until I've had a chance to work on it some more
before using it.

[mpls-linux-general] Re: ldpd doesn't start properly

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

I have some extra information on this. Attached is a packet capture
when the two LDP neighbours connect (just before one of them dies)

The file is in libpcap format (viewable with tcpdump or with ethereal)

[mpls-linux-general] ldpd doesn't start properly

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

I'm trying to get ldpd to work and I'm having difficulties.

I'm connecting to ldpd using telnet and this is how I configured my LER:

e1:/home/irina.dumitrascu# cat /usr/etc/ldpd.conf
!
! Zebra configuration saved from vty
!   2006/03/13 16:01:36
!
hostname uml-1
password root
enable password root
!
interface eth0
!
interface eth1
 mpls ip
!
interface eth2
!
interface eth3
!
interface gre0
!
interface ip6tnl0
!
interface lo
!
interface mpls0
!
interface sit0
!
interface teql0
!
!
mpls ldp
 egress connected
!
line vty
!

On the LSR I set up both interfaces with mpls ip (eth0 and eth1), but
when I try to start ldpd on the lsr, it says:

e2:/home/irina.dumitrascu# ldpd -u root -P 6222
ldpd: ldp_interface.c:59: ldp_interface_create2: Assertion
`li->iff.index' failed.
Aborted.

I can start it if I comment out the 'mpls ip' lines from interface
eth0 and eth1.

After I manage to start LDP on the LSR, and try to run  show ldp I get
an error message: 'There isn't an active LDP instance.' This happens
after I have have configured manually the interfaces (mpls ip).

When I have the lsr manually configured (172.16.0.3) and the next ler
running (172.16.0.2), and on the lsr I issue the command 'mpls ldp'
this is what happens:

* the ler is constantly sending out LDP Hello packets
* when I issue mpls ldp on the lsr, the lsr sends a LDP Hello, and
then freezes (actually only ldpd freezes)

This is the output of tcpdump

Do you have any idea why this doesn't work?

[mpls-linux-general] ldpd runs, but doesn't do anything

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

Hello

I've managed to compile quagga (from the src.rpm) and install it to my
computers. I followed the instructions from the readmes in the
compilation process (replaced /usr/include and ran create-links) and
aparently quagga is compiled ok.

I've tried and successfully set up a small ospf network, which works ok.

This is how I start up quagga:

#cp /usr/etc/zebra.conf.sample /usr/etc/zebra.conf
#zebra -u root -g root -d
#cp /usr/etc/my_configured_ospfd.conf /usr/etc/ospfd.conf
#ospfd -u root -g root -d
#cp /usr/etc/ldpd.conf.sample /usr/etc/ldpd.conf
#ldpd -u root
There is no such command.
Error occured during reading below line.
mpls ip


So, I modified /usr/etc/ldpd.conf to this:
!
! Zebra configuration saved from vty
!   2002/03/23 17:07:30
!
hostname uml-1
password root
enable password root
!
!mpls ip
!
interface lo
!
!interface eth0
! mpls ip
!
line vty
!

And now ldpd starts running when starting up:
# ldpd -u root
    (it shows no output from here on end)

Next, I connect using vtysh. The first problem is this: when I run a
show running-config I only get the hostname of Router (set by
zebra.conf) and a hostname of ospfd (set by ospfd.conf, obviously).
The thing is, I don't get a hostname of uml-1 (set by ldpd.conf).

The plot thickens because, nomatter what mpls commands I issue (for example=
:

e2# configure terminal
e2(config)# mpls ldp
e2(config-ldp)#
e2(config-ldp)# lsr-id 172.16.1.3
)
when I issue a show running-config, I don't see any mpls related
commands (and it doesn't save them either).

Aparently, ldpd doesn't communicate with zebra (or vtysh).

Next, I tried launching ldpd with a port (6222) and connected to that
port with telnet.
I got a console and I could issuse some commands and aparently they
get saved in the configuration files. However, I get no output from
the ldpd that started as non-daemon.

I'm not sure if ldpd doesn't work with vtysh (and if this is the real
problem), or if I did something wrong and I should stop and go back
and fix it.

Thank you for your time

[mpls-linux-general] How can I use the "mpls" command

[mynor <myn...@gm...>]

Hello there

I already install mpls kernel 1.950 in my FC4.
After I load the mpls module using this command "modprobe mpls4", I still
cannot use the "mpls" command

Actually before this I using the old version and successfully configure the
LSR.

Now when Im using the new kernel, I cannot use the "mpls" command.

Please someone help me

Im using rpm package provide by JLeu to install the kernel

Re: [mpls-linux-general] Re: quagga mpls doesn't compile

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

Ok

My gcc version is: gcc version 3.3.6 (Debian 1:3.3.6-7)

and my assambler version is: as -v
GNU assembler version 2.15 (i486-linux-gnu) using BFD version 2.15

But it works now...

However, I had to compile it on all machines, because I couldn't copy
the source to another machine and issue a make install, because it
would realize that it wasn't compiled for that machine and it would
automatically run a ./configure... So I had to do it the hard way.

Next, I'm trying to learn how to generate a deb package from it; Maybe
when I'm convinced that all deb packages I converted from your rpms
(+quagga) work fine, I'll post them to a web site and give you the
link so that others may use them, if they find them usefull.

Thank you

The code you commented out is just for debugging purposes, so you
approach is fine.

What version of gcc are you using?

Re: [mpls-linux-general] TTL is working

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

The only manual for the 'mpls' command is the 'help' output (mpls help)
I would gladly accept documentation (even partial) submissions.

You can set the EXP bits via the set-exp instruction.  You can map EXP
bits to the tcindex (via the exp2tc instruction) which can be used by
the linux traffic scheduling system (tcindex classifier).

If you really want to give that I try I suggest you read the LARTC howto fr=
om
http://lartc.org/ and get it working with IP traffic before trying it
with MPLS.

[mpls-linux-general] TTL is working

[Irina D. <dum...@gm...>]

Hi,
I've tried your advice and i've removed the commands with "xc add",and the
TTTL is how i expected.
Some of mpls's options i understood,but not all of them. Do you have a
manual page for mpls(even if it's not complete)?

Does your implementation of mpls-linux permit the change of the EXP bits of
the MPLS header,and if yes,how could i do that?
Also, does a MPLS-LSR interpret these bits as a priority and does it know
how to forward packets depending on the priority?


Thank you very much.

[mpls-linux-general] Re: quagga mpls doesn't compile

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

Hello

I was able to compile quagga after following James tip in commenting
some code. Here's what I did, maybe it will be usefull for somebody
else:

In ldpd/ldp_fec.c i commented out the route_dump_node line like this:
static void walk_tree(ldp_global *g) {
  LDP_ENTER(g->user_data, "walk_tree");
  //route_dump_node(g->fec_tree);
  LDP_EXIT(g->user_data, "walk_tree");
}

and in lib/table.c I commented out this method:
/* Dump routing table. */
/*static void __attribute__ ((unused))
route_dump_node (struct route_table *t)
{
  struct route_node *node;
  char buf[46];

  for (node =3D route_top (t); node !=3D NULL; node =3D route_next (node))
    {
      printf ("[%d] %p %s/%d\n",
              node->lock,
              node->info,
              inet_ntop (node->p.family, &node->p.u.prefix, buf, 46),
              node->p.prefixlen);
    }
}
*/

Now, quagga compiled (apparently ok) and I am ready to start tests using it=
.

Thank you very much for your assistance, and please, tell me if I did
something wrong by commenting those lines.

Hi James,
Ive just found a cool wiki, you should use it to
document your mpls-linux.

[mpls-linux-general] How can I contact Pim Van Heuven?

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

Hello

I'm interested in finding support for RSVP-TE for label distribution
for mpls-linux, plus Diffserv capabilities. I saw that on James site
there is a remark that there is an open source implementation of
rsvp-te for linux, that uses mpls-linux, so I searched for it.

I found a lot of notes all leading to this site:
http://dsmpls.atlantis.rug.ac.be, wich is offline. The contact details
are these:

Pim Van Heuven            Ghent University - IMEC
Department  of  Information  Technology   (INTEC)
Sint-Pietersnieuwstraat, 41 B-9000, Gent, Belgium
pim...@in...
        DiffServ/MPLS(RSVP-TE) for Linux:
        http://dsmpls.atlantis.rug.ac.be

My question is: Does anyone know where the implementation of RSVP-TE
can be located? Is it still alive?

Thank you for your replies

Re: [mpls-linux-general] quagga mpls doesn't compile

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

quagga-mpls does not support RSVP-TE.  There is a group work on
porting an RSVP-TE implementation to quagga-mpls.

As far as your compile error, I do not have an answer.  My guess is that
there is an error earlier in the compile process that is preventing
lib/table.c from compiling.  Being that the whole walk_tree() is
just for debug, your could try comment out the call to route_dump_node().

Re: [mpls-linux-general] how to change the ttl when switching from mpls to ip

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

I'm betting you've found a bug with the 'advanced feature' I referred to
yesterday.

Please try this, for each direction remove the "mpls xc" on the egress
LER and then add an IP route for the egress hosts 'dummy0'.

Assuming you have executed all of the commands in the Two LER, one LSR exam=
ple,
here is how to 'undo' the 'advanced feature':

traffic from A to B, modify LER2 as such:

    mpls xc delete ilm_label gen 1001 ilm_labelspace 0 nhlfe_key 0x2
    ip route add 10.0.0.2/32 via 192.168.1.5

traffic from B to A, modify LER1 as such:

    mpls xc delete ilm_label gen 2001 ilm_labelspace 0 nhlfe_key 0x3
    ip route add 10.0.0.1/32 via 192.168.0.1

Let me know how this works for you.

[mpls-linux-general] how to change the ttl when switching from mpls to ip

[Irina D. <dum...@gm...>]

hello,
i've run the tests with 2 LERs and one LSR and I've observed that the TTL i=
s
decremented on the MPLS link, but it is disregarded in the Egress router,so
the IP packet leaves with the TTL it had when it entered the MPLS
network.(the MPLS network is seen like one hop).
How can i change the TTL in the MPLS Egress node?(so that the TTL from MPLS
packets is copied in the TTL field of IP packets. )

I've tried with the option "no_propagate_ttl" : mpls nhlfe change key 0x3
no_propagate_ttl, but i've observed that at the LER ,it doesn't copy the TT=
L
field from the IP packet and the MPLS packets leave with the TTL=3D255.



PS: i've used your advice with the exemple with 2 LERs and 1 LSR and it
works.
Thank you very much
