[mpls-linux-general] Problems with LDP

[priya S. <mpl...@ya...>]

haii

    I have this problem with lsp setup. I have a
simple network setup as shown below.

          ---- LSR1 ----
         |              |
Host1 --- LER1          LER2--- Host2
         |              |
          ---- LSR2 ----

I have a IP to FEC binding in LER2 and the routing
table and mpls_out contents are as below (which is
fine and as expected)

root@localhost LER2]# ip route sh
10.0.4.0/24 dev eth1  scope link
10.0.1.0/24 via 10.0.3.1 dev eth2 lsp 0x3  proto zebra
metric 20 equalize
10.0.3.0/24 dev eth2  scope link
10.0.12.0/24 dev eth0  scope link
127.0.0.0/8 dev lo  scope link

[root@localhost LER2]# cat /proc/net/mpls_out
0x00000003 68500/5753838/0 2 PUSH(gen 10002)
SET(eth2,10.0.3.1)
0x00000004 447/36612/0 1 PUSH(gen 10005)
SET(eth2,10.0.3.1)
0x00000008 15/738/0 1 PUSH(gen 10020)
SET(eth2,10.0.3.1)

BUT, I donot have a similar IP--FEC binding at LER1.
The ip route show and the cat /proc/net/mpls_out
commands show the following output (which packets take
which LSPs-- 0x1a or 0x1b in mpls_out below)

[root@localhost LER1]# ip route sh
10.0.4.0/24 via 10.0.2.2 dev eth2  proto zebra  metric
20 equalize
10.0.1.0/24 dev eth1  scope link
10.0.2.0/24 dev eth2  scope link
10.0.3.0/24 via 10.0.1.2 dev eth1  proto zebra  metric
20 equalize
10.0.12.0/24 via 10.0.1.2 dev eth1  proto zebra 
metric 30 equalize
10.0.11.0/24 dev eth0  scope link
127.0.0.0/8 dev lo  scope link

[root@localhost LER1]# cat /proc/net/mpls_out
0x0000001a 2845/238980/0 2 PUSH(gen 10109)
SET(eth1,10.0.1.2)
0x0000001b 0/0/0 1 PUSH(gen 10111) SET(eth1,10.0.1.2)


What could be the problem? The FEC binding at LER2 was
automatic but not at the LER1. I just enabled the
interfaces for LER1, LSR1 , LSR2, LER2 on the mpls
network using "mpls ldp". 
    Also please let me know if there is any
documentation that could explain as to how the ldp for
mpls-linux sets up labels for all the networks in the
LSRs and LERs.
    Thanks in advance

Re: [mpls-linux-general] setup information

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

I think you do not understand the purpose of the 'ip route'
commands.  They are only needed on the LERs and are supposed to map
traffic to the LSP.

In this example you will want the ingress route to be the interface
address of the egress, and vice versa.

The LSRs do not need 'ip route' they are not supposed to be routing,
they are 'switching'

Re: [mpls-linux-general] LSR setup

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

Did you bind a route to the LSP?

Show me all of the command you have executed on each box and maybe I can
point out any mistakes.

Yes.  the iproute2 command has changed in a similar way:

ip route add 1.1.1.1/32 via 11.0.1.2 spec_nh 0x8847 0x2

[mpls-linux-general] LSR setup

[<iq...@cc...>]

Thanks for the idea, I overcame the problem of

Bind In2Out add:No such process

Now I have the following entries in mpls_in on my LSR

0x40004400 19/1672/0 gen 17 0 8 POP FWD(0x00000002)
0x40004000 14/1232/0 gen 16 0 3 POP FWD(0x00000003)

but I still am unable to ping Egress from Ingress.

Ok, it seems to work ... But what means the 0x8847 ?
Are there any changes on other commands ?

You are running a 2.6 kernel?  The format of the iptables and iproute commands
have changed (with respect to MPLS).  I have implemented a non-MPLS specific
nexthop system called (SPEC NH for special nexthop).  The SPEC NH system is
implemented in the 2.6 kernels and not in the 2.4 kernels.

Try this command instead:

/sbin/iptables -A OUTPUT -d 1.1.1.2/32 -j spec_nh --spec_nh 0x8847:0x2

Where 1.1.1.2/32 is some destination you want mapped to the LSP and 0x2
is the key for the out-going label.

Re: [mpls-linux-general] Loss of next hop information if rebooting next hop router

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

This is behaving as designed.  When the interface goes down, MPLS needs to
release all of the info for that interface.  In the case of out segments
it just removed the nexthop info.

[mpls-linux-general] Loss of next hop information if rebooting next hop router

[<Jon...@cs...>]

Dear all,

Just wondering if this is a desirable feature or not...

I use mplsadm2 to set up a LSP across three Linux mpls boxes (say, A, B
and C). If I rebooted box B, the next hop information of box A
"sometimes" disappeared!!!

For example, the original information of /proc/net/mpls_out was like
this:

0x0000000e 0/0/0 2 PUSH(gen 712111) SET(eth2,10.70.10.1)=20
0x0000000f 0/0/0 2 PUSH(gen 712112) SET(eth2,10.70.10.1)=20
0x00000010 0/0/0 2 SET(eth1,10.60.10.2)=20

If I rebooted the next hop mpls router (10.70.10.1), the section
"SET(eth2,10.70.10.1)" was automatically removed from the
/proc/net/mpls_out. i.e. the file looked like this:

0x0000000e 1476/157256/0 2 PUSH(gen 712111)=20
0x0000000f 1549/168728/0 2 PUSH(gen 712112)=20
0x00000010 2977/311864/0 2 SET(eth1,10.60.10.2)=20

Is it supposed to be like this??

Thanks for your comments...

Jonathan

Re: [mpls-linux-general] iptables+mpls

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

Most likely you are not running the correct copy of iptables.
(or you do not have permission to load the iptables extentions).

Do a:

rpm -qa | grep iptables

Then do a 'rpm -ql' with the result from the previous command.  For
example:

[jleu jleu-laptop 11:49am] ~-> rpm -qa | grep iptables
iptables-1.2.9-2.3.1spec_nh
iptables-ipv6-1.2.9-2.3.1spec_nh
[jleu jleu-laptop 11:50am] ~-> rpm -ql iptables-1.2.9-2.3.1spec_nh
/etc/rc.d/init.d/iptables
/etc/sysconfig/iptables-config
/lib/iptables
/lib/iptables/libipt_CLASSIFY.so
/lib/iptables/libipt_CONNMARK.so
...

Then do a 'which iptables' and make sure the path to the one your running
matches the path to the one in the RPM.

If you still can't figure it out, send me the full script of a terminal
session where you execute the above commands, the command you are trying to
get working, and a 'iptables --version'

iptables -A OUPUT -d 192.168.13.1 -t mangle -j MPLS --set-key 0x2

at first the command set-key wasn't found and when i del it from
the command i get the error: libipt_MPLS.so wasn't found ...

what did i wrong and how can i fix it? why didn't the rpm install the .so ?


best regards

eth0 0 10
0x00000002 9/756/0 1 PUSH(gen 16) SET(eth0,172.16.70.86)

mpls_* for my egress is

The problem is a bug with older version of mplsadm2.  You cannot create an
outsegment and set it's instructions in one command.  Do it in two commands
and it will work fine:

mplsadm2 -A -O 0
mplsadm2 -O <key output from previous command> -o push:gen:18:set:eth0:ipv4:10.105.1.26

[mpls-linux-general] Out label insertion error

[K S. K. <san...@cs...>]

Hi

I am getting the following error ('Illegal seek') when
I created an out label. But /proc/net/mpls_out shows the right entries.
I checked the LSP. It is working properly i.e.,
the destination machine pinging properly using the lsp I created.
Even turning on debugging mode does not help.

I do not understand what this error stands for? Any ideas.....



[root@veronica root]# mplsadm2 -A -O 1 -o push:gen:18:set:eth0:ipv4:10.105.1.26
Key: 0x00000003
Out Segment add: Success
Out Instr: Illegal seek

If you don't stand for something, you'll fall for everything.

Re: [mpls-linux-general] Egress Router, how?

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

Are you running a MPLS enabled kernel?  Which version?

Take a look at http://mpls-linux.sf.net/ on how to get debugging info
for mplsadm2 issues.

[mpls-linux-general] Egress Router, how?

[Jung J. <jj...@hs...>]

Hi!

I have a simple network...:






PC2				PC1
		10.130.0.0/16
eth0 -----------switch------eth1
0.6			0.20
---------		---------
|	|		|	|
|	|		|	|
|	|		|	|
---------		---------
0.6			0.20
eth1------------switch------eth0
		10.131.0.0/16

PC2 sends on his eth0 interface MPLS packets with label=1024 (not via
mplsadm)
(with destination IP=10.131.0.6 (his other IP))
PC1 receives this packets, and i would like PC1 to pop the label
and forward it as an IP packet (check the route table, and then
forward it to PC2-eth1)
PC1  runns mplsadm2...

How should i do that?

i tried:
PC1:
mplsadm2 -vL eth1:0
mplsadm2 -vAI gen:1024:0
mplsadm2 -vI gen:1024:0 -i pop:peek
no such device or address

any idea?????????
How should i do that?

Re: [mpls-linux-general] Make Problem with MPLS linux-kernel patch

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

All development is occuring on 2.6.  I suggest moving to a 2.6 UML kernel.
I use UML for my development environment.

Get mpls-linux-1.922.tar.gz from:

http://sourceforge.net/project/showfiles.php?group_id=15443

You might want to check out some of the UML tools I have posted to

What mplsadm2 command did you use to create the outgoing label?

[mpls-linux-general] Make Problem with MPLS linux-kernel patch

[Josef P. <jo...@pe...>]

Greetings to all,

I use Debian sarge and want to do some MPLS Network Simulation with User
Mode Linux

i have the Kernel 2.4.24 and wanted to patch it with the MPLS
linux-kernel.diff to 
enable the MPLS Support.

but i always get errors when i want to make a Kernel Package for the UML
MPLS Kernel:

With linux-kernel-patch.diff (Version 1.722) I get the following error
message:

vmlinux.o(.text+0xfa568): In function `rt_set_nexthop':

With linux-kernel-patch.diff (Version 1.922) I get the following error
message:

Can anyone send me the right patch, or has anyone experiences with debian,
mpls and usermodelinux? 


I hope anyone can help me, i stuck at this problem for a long time now.

[mpls-linux-general] entry in mpls_out

[<iq...@cc...>]

After I carry out the following command

ip route add 11.0.1.2/32 via 11.0.1.2 lsp 0x2

and then do "cat /proc/net/mpls_out"

I get "0x00000002 0/0/0 1 PUSH(gen 10000) SET(eth1,255.255.255.255)" 

instead of "0x00000002 0/0/0 1 PUSH(gen 10000) SET(eth1,11.0.1.2)"

Should I change the mpls_out file myself or is there some way to fix it?

Waiting for ur help.
