[mpls-linux-general] can anyone help me ? (urgent!!!)

[venda - y. <vy...@eu...>]

Hi all, 
We are a new user of mpls-linux. We  want to implement mpls in our laboratory with 6 computer. We have run mpls-linux-1.0 in red hat 7.2 and kernel 2.4.7 by following the instruction that included in mpls-linux-1.0/readme. Base on the instruction first we get kernel 2.4.7 then untar this kernel. After uncompressing mpls-linux-1.0 , we patch linux-mpls.diff into the kernel and compile the kernel. We have done that steps successfully (we knew it by running !'dmesg | grep MPLS!( and we get the mpls version). The next step is enterting the directory /mpls-linux-1.0/utils then run !'make all!(, then edit the content of /etc/profile by adding :
   export MPLSHOME=/usr/src/mpls-linux-1.0
   export PATH=$PATH:$MPLSHOME/scripts:$MPLSHOME/utils
then run !(make mplsadm!(. 
The topology that we use is like this :

Host A ----- LER A ------ LSR ------ LER B ----- Host B
   Eth0   eth0  eth1   eth2 eth0   eth0  eth1   eth0

The ip number that we use :
Host A 3 eth0 : 192.167.1.1
LER A 3 eth0 : 192.167.1.2
	     eth1 : 192.167.2.2
LSR  3    eth2 : 192.167.2.3
	     eth0 : 192.167.3.3
LER B 3 eth0 : 192.167.3.4
  	     eth1 : 192.167.4.4
Host B 3 eth0 : 192.167.4.5

Host A and host B -3 without MPLS 

LER A :
root# mplsadm -v !VL eth0:0
root# mplsadm !Vv !VL eth1:0
root# mplsadm !Vv -A !VB !VO gen:1234:eth1:ipv4:192.167.2.3 !Vf  192.167.4.5/32
root# mplsadm !Vv !VA !VI gen:4563:0
mpls_in: 40474c00 0/0/0 gen 4563 0 POP PEEK
mpls_out: 40134803 0/0/0 PUSH (gen 1234) SET (eth1, 192.167.2.3)

LSR:
root# mplsadm -v !VL eth0:0
root# mplsadm !Vv !VL eth1:0
root# mplsadm !Vv !VA !VI gen:1234:0 !VO gen:2341:eth0:ipv4:192.167.3.4 !VB
root# mplsadm !Vv !VA !VI gen:3456:0 !VO gen:4563:eth2:ipv4:192.167.2.2 !VB
mpls_in : 40134800 0/0/0 gen 1234 0 POP FW (40249402)
    40360000 0/0/0 gen 3456 0 POP FW (40474c04)
mpls_out: 40249402 0/0/0 PUSH (gen 2341) SET (eth0, 192.167.3.4)
    40474c04 0/0/0 PUSH (gen 4563) SET (eth2, 192.167.2.2)

LER A :
root# mplsadm -v !VL eth0:0
root# mplsadm !Vv !VL eth1:0
root# mplsadm !Vv -A !VB !VO gen:3456:eth0:ipv4:192.167.3.3 !Vf  192.167.1.1/32
root# mplsadm !Vv !VA !VI gen:2341:0
mpls_in: 40249400 0/0/0 gen 2341 0 POP PEEK
mpls_out: 40360002 0/0/0 PUSH (gen 3456) SET (eth0, 192.167.3.3)

but when we ping host A from host B and also the opposite (host B from host A) we get the same output with the ordinary tcp/ip (ping host A from host B by using linux without mpls). We mean, if we use mpls to ping host A from host B it need b 1.485 ms and it is the same time that we need to ping host A from host B without mpls. 
So we want to ask is there any mistake with all the things that we!&ve done ? because it looks like that our mpls is not running well. and what should we do with ldp-portable ? (we have download it, but we don't know how to use it to support mpls)
So can someone tell us how to fix it ? and how we will know that the mpls have run properly ? we waiting for your suggestion , thank you.
venda, andy, amiek.
