[mpls-linux-general] A question about quit( )

[<zjh...@so...>]

hi,Jim
I have read your code about the command func :quit( ).In linux you use the system API "exit( )"to finish almost all the work. They work well in Linux.

I have also tried your code in vxworks .Using the quit command ofent make program down.
So I want to write a quit( ) but not use the "exit( )",do everything by myself.Can you 
give me some advice:such as the sequence to close"session,interface,adjacency,global "etc.

I am busy in try to port your code to vxworks.Once I finish it ,I will share my idea and my
experience and my code with all  in the mailing list.I will try my best.

All thanks!!

Your sincerely :zhang jianhui

[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
Erik Linder

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

This maynot be the problem but you also need to set the 'labelspace' on the
incoming interfaces:

mplsadm2 -L eth1:0

Another thing you can try is to turn on mpls kernel debugging:

mplsadm2 -d

Look at the ouptut from 'dmesg' or in /var/log/messages.

Removing the entities will tear down the sessions/adjacecncies.  Then removing
the global will cleanup the porting layer.

Excellent!  I have just starting working on ldp-portabel again, so hopefully
I can help you fix any LDP related bugs that you find.
