[mpls-linux-general] MPLS checking

[<aj...@ko...>]

 Hello all (Jim)

We just started working on MPLS-Linux.
My problem is when I pinged C from A , how to know that packet is MPLS or normal
IP. I used tcpdump and ethereal to check it(if the packet going from A to B is
MPLS).I didn't see any mpls packet..

 My network is as 

                              eth0
  			  202.141.151.78 (gw)
     -----       LSP         -----
     | A | ----------------- | B | 
     -----                   -----
  202.141.151.76               \          -----
      eth0                      \---------| C |
                                          -----
              				202.141.152.3

Where Host A and B MPLS enabled. I have created route and FEC at A.  The packet
originating from A to C , B act as gateway.  

I have created static route ( not used LDP) , the command used are ..

On host A gave following commands--------
  route add -host 202.141.152.3 gw 202.141.151.78
  mplsadm -A -B -O gen:16:eth0:ipv4:202.141.151.78 -f 202.141.152.3/32
  mplsadm -A -I gen:17:0
  mplsadm -L eth0:0

There are enteries in /procs/net/mpls* files.

Can u please tell me what is problem here (in network or in our method of
checking )  , and method to check MPLS packets.
 
I am having Red Hat Linux 7.1 and mpls-linux-0.993.

 Thanks in advance..
