Re: [mpls-linux-general] (off topic?) ip route...

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

You should check to make sure you have the iproute package installed
on your system:

rpm -qa | grep iproute

If not, you will need to compile a version.  In the following e-mail
I explain how to compile iproute from source.

You're very close.  The problem is that even though you have compiled a
MPLS enabled version of 'ip' and 'iptables' these new versions are not
in your shells path.  Type 'set' at your shell prompt and look for 'path'=
,
this are the directories that your shell looks when searching for program=
s
to execute.  Lets look at an example:

[root@uml1 root]# set
<snip>
PATH=3D/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
<snip>
[root@uml1 root]# which ls
/bin/ls

Whenever you type the command 'ls' your shell looks through its PATH
and tries to find the binary for the 'ls' command.  In this case the
'ls' binary is found in '/bin'.  Since '/bin' is in my shells PATH
it will execute the command.  If I try to execute a command that is not
in my PATH it will say:

[root@uml1 root]# foo
-bash: foo: command not found

In fact typing 'which foo' explains it.

[root@uml1 root]# which foo
/usr/bin/which: no foo in (/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr=
/sbin:/usr/bin:/root/bin)

Now lets get to your case.  There is a version of 'ip' that was installed
with RedHat 7.2.  You can verify this by typing:

[root@uml1 root]# rpm -ql `rpm -qa | grep iproute`
<snip>
/sbin/ip
<snip>

[NOTE those are back ticks (`) not apostrophes (')]

[root@uml1 root]# which ip
/sbin/ip

So when I type any command that begins with 'ip' the shell will find
'ip' in /sbin/ip and use that binary.

But there is also a version you have compiled.  I'll go through how I
compiled it for completness:

[jleu jleu-laptop 2:54pm] ~/personal/export/test-> ls
iproute2-2.4.7-now-ss010824.tar.gz  mpls-linux-1.172.tar.gz

etc/    include-glibc/  Makefile  README.decnet  tc/
[jleu jleu-laptop 2:57pm] ~/personal/export/test/iproute2->

So I have a MPLS version of 'ip' right?  So I can just type:

[jleu jleu-laptop 3:03pm] ~/personal/export/test/iproute2-> ip route add =
10.0.0.0/24 via 63.96.16.129 lsp 0x2
Error: either "to" is duplicate, or "lsp" is a garbage.

WRONG! (as you can see) Because by just typing 'ip' the shell is searchin=
g
the PATH.  The first match it find is /sbin/ip which is NOT the version
I just compiled.

So where is the 'ip' binary I just compiled?

[jleu jleu-laptop 2:58pm] ~/personal/export/test/iproute2-> find . -type =
f -name 'ip'
./ip/ip
[jleu jleu-laptop 2:58pm] ~/personal/export/test/iproute2-> cd ip

/home/jleu/personal/export/test/iproute2/ip
[jleu jleu-laptop 3:01pm] ~/personal/export/test/iproute2/ip->

Ahh.  So I just complied an MPLS enabled version of 'ip'.  The new binary=
 is
located at '/home/jleu/personal/export/test/iproute2/ip/ip' which is _not=
_ in
my PATH.  So how do I execute THAT specify version?

I can do it one of two ways:

[jleu jleu-laptop 3:04pm] ~/personal/export/test/iproute2-> /home/jleu/pe=
rsonal/export/test/iproute2/ip/ip route add 10.0.0.0/24 via 63.96.16.129 =
lsp 0x2

-or-

[jleu jleu-laptop 4:08pm] ~/personal/export/test/iproute2-> cd ip
[jleu jleu-laptop 4:09pm] ~/personal/export/test/iproute2/ip-> ./ip route=
 add 10.0.0.0/24 via 63.96.16.129 lsp 0x2

I hope this helps.  You can apply much of this same knowledge to 'iptable=
s'

[mpls-linux-general] (off topic?) ip route...

[a a <dre...@ho...>]

This question might be of-topic, but I'll give it a try here.

I'm a linux newbie and have been given the task to get a mpls router up and 
running... I have followed the instructions that where in the mpls-linux-1.1 
- pkt, but when I try the routing stuff it cant execute the command
ip route ...

What have I forgotten when compiling my kernel?
Btw, I'm using rh 7.1 with a 2.4.20 kernel...

Would be grateful for any help!

[mpls-linux-general] length of Counters in mpls_in

[Stefan W. <ma...@st...>]

Hello,

the file /proc/net/mpls_in contains three counters for Octets,Packets, Errors. 
Are they 32-bit counters or 64-bit counters, or does this depend on the 
architecture?

Regards,

Stefan Winter

[mpls-linux-general] urgent!!! compare IP to MPLS

[roro <mpl...@16...>]

hi,all
   I have install mpls-linux and try to transfer files between two hosts using mpls.Then I compare the time spent  between 
mpls and ip. But I found that the time spent under mpls is more than under ip. 
   I think it is because the host number is 2 and there is no core LSR so the advantage  can't be observed.Is it right?
   And has someone done the similar  test? and could you share the result with me?
   I'm eager for your help,thanks in advance.

[mpls-linux-general] linux mpls and cisco

[Dan N. <Da...@ce...>]

Hello,
I have been searching in the archives of the lists for "success stories" 
on the subject, but I could not find one.
The question is: has anyone run successfully linux mpls with a cisco box?
I couldn't.
I have successfully tested static label swapping, ldp and rsvpd before 
between linux boxes (so as far as I can see it, my kernel, zebra, etc 
are ok)
I have a cisco box connected to a linux machine. The goal is for now to 
have a ldp session between the two.
They both run ospf, I have a dummy intf. on the linux and another 
physical interface on the cisco, and ospf runs just fine (I can ping any 
of the interfaces that I am interested in)
The mplsd config is the following:
[root@w02gva etc]# cat mplsd.conf

mpls ldp
!
interface eth2
 mpls ldp

The cisco setup is like this:
ip cef distributed
no ip domain-lookup
mpls label protocol ldp
mpls ldp logging neighbor-changes
no mpls traffic-eng auto-bw timers frequency 0
interface FastEthernet2/0/0
 ip address 192.168.0.2 255.255.255.0
 no ip directed-broadcast
 full-duplex
 mpls ldp discovery transport-address 192.168.0.2
 mpls label protocol ldp
 tag-switching ip
 no cdp enable
end
The cisco is a rsp7000 with ios 12.0.25S. I have tried a 12.2.14S1 with 
the same results (lack of results, that is)
The output of show mpls ldp neighbor on cisco is null. The one on zebra 
is like this:

w02gva# show ldp neighbor
Peer LDP Ident: 10.0.0.1:0; Local LDP Ident: 192.168.2.1:0
        TCP connection: 0.0.0.0.646 - 192.168.0.2.646
        State: NON-EXIST; Msgs sent/recv: 0/0; UNSOLICITED
        Up time: 12194d 14:36:42
        LDP discovery sources:
          eth2
        Addresses bound to peer:

As I remember from the linux setup, the Addresses bound to peer section 
should not be null. Also, from the rfc, state: NON-EXIST doesn't sound 
good (I don't remember what the linux setup said). I also did an 
ethereal capture on the interface. It seems like the linux box tries to 
initiate a tcp connection to the cisco box on tcp port 646, it fails, 
and never tries again. I also noted the csn error message in mplsd, but 
i get the same results if I try to comment out the various csn checks in 
the source code.
I would be glad to receive at least a configuration dump of a succesful 
setup. Of course, comments on my setup are also welcome.
Thank you,
Dan Nae

You are not running an MPLS enabled kernel.  YOu can grab a redhat 8.0
RPM with a MPLS enabled kernel from:

ldp-portable is meant to be arch independent.  MPLS forwarding is arch
dependent.  SO to get the details as to how ldp-portable interacts
with MPLS forwarding you will have to look at the 'porting layer' used
by ldp-portable when talking with zebra and mpls-linux.  To do this=20
apply the zebra-ldp patch to a zebra source distribution and look
in zebra/mplsd/impl_mpls.c

I don't understand your question.  Do want VRFs on linux? If so look
at http://linux-vrf.sf.net/

Trouble shoot of MPLS networks with existing show commands is quite hard
to do.  I partake in MPLS interoperablity sessions and it is always a tedious
task to trouble shoot the problems we see.

The simple asnswer is yes there are commands, but you have to know how to
pull pieces of info from one show command ans use it in another one.

I do not have a cisco box avilble right now other wise I would give
you some examples.

The questions your asking are all related to how LSPs are presented to other
MPLS signaling protocols and routing protocols.

I just gave a 'class' on advanced aspects of MPLS which covered how this
works.

It all has to do with having enties in the ingress LSRs IP routing table
that correspond to the router-id of the egress LSR.  When this happens
indirect LDP recongnize that the desired result is to map labels into
the LSP assocaited with the router-id.

You can use IGP short-cuts or IBGP to map more FECs onto an LSP.

Re: [mpls-linux-general] iptables-1.2.7-mpls.diff

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

The .rej file is the part of the patch that failed.  Typically what you have
to do is inspect the .rej and the original file and figure out how to
manually apply the patch (hand type the change).  If I remeber correctly
it is going to be a one line fix where you will have to add MPLS to the list
of modules to compile and install.

Once you have a compiled version of iptables then you should be
able to use the syntax out lined in README.iptables.

[mpls-linux-general] interaction mpls-ldp. (call setup)

[a a <dre...@ho...>]

Hi!

I'm an exjobb student from Uppsala university and I'm currently 
investigating the MPLS architecture. I'm interested in how the call setup in 
MPLS is done and is currently looking at the source-code for your project...
How do the mpls-linux interact with ldp? In what function? (Where in your 
source-code do I start digging?)

My guess would be the lsr_labelmanager.c/h but, these files are empty...

pls, help!
