[mpls-linux-general] ARP and MPLS

[Linder E. <li...@en...>]

Hi,
I have put up a very simple network with 2 pc . After doing all the
configuration stuff, I try to ping B from A and there I get something
strange: tha ARP request are sent but keep unanswered
Tcpdump on the emitting eth gives:
17:26:34.873599 arp who-has 137.194.214.142 tell 137.194.214.141

and it'is all. I don't know what to do , or start looking where
something has got wrong.

I hope someone can help me

Here is my config:

  ---------             ---------
  |   A   |             |   B   |
  ---------             ---------
      |eth1                 |eth1
      |.141                 |.142
 -----------------------------------
A
ifconfig eth1 137.194.214.141 netmask 255.255.255.192 up
 
B
ifconfig eth1 137.194.214.142 netmask 255.255.255.192 up

Sur A:
   mplsadm2 -A -O gen:16:eth1:ipv4:137.194.214.142  
   iptables -A OUTPUT -d 137.194.214.142/32 -j MPLS --set-key KEY1
   mplsadm2 -A -I gen:17:0
 
   Ou KEY1 est le resultat renvoye par la commande precedante 'mplsadm2'

 
 Sur B:
   mplsadm2 -A -O gen:17:eth1:ipv4:137.194.214.141
   iptables -A OUTPUT -d 137.194.214.141/32 -j MPLS --set-key KEY2
   mplsadm2 -A -I gen:16:0
 
      Ou KEY1 est le resultat renvoye par la commande precedante
'mplsadm2' 

Sur les 2 host:
   mplsadm2 -L eth1:0


PS: I tried using route instead of  iptables and I got the same result
