[mpls-linux-general] Re: LDP (linux-port)

Hi,

   Mr Thorsten, I appreciate the help provided. However, I do not quite
understand your way of configuring the 2 PCs. This is what I have done..
maybe if u have the time, you can advice me further on the things I have
missed out.

   I have just 2 Linux PCs joined together by a Ethernet cable. Both PCs
have the most recent MPLS patch
applied to kernel 2.4.13. To configure them, I performed these precise steps
in the exact order as typed.

a) LSR A:

   1) ifconfig eth0 192.168.0.1
   2) ifconfig lo 10.0.0.1
   3) ip addr add 10.0.0.1/32 dev lo
   4) ip route add 10.0.0.2/32 via 192.168.0.2

b) LSR B:

   1) ifconfig eth0 192.168.0.2
   2) ifconfig lo 10.0.0.2
   3) ip addr add 10.0.0.2/32 dev lo
   4) ip route add 10.0.0.1/32 via 192.168.0.1

c) LSR A:

   1) Start ldp_linux.
   2) add global 10.0.0.1
   3) add interface eth0

d) LSR B:

   1) Start ldp_linux.
   2) add global 10.0.0.2
   3) add interface eth0

   On both PCs, I sniffed the line using Ethereal.

    I encountered the following problem. A session seemed to be established
as show "database" and show "session" do produce some results. But when I
tried to read the /proc/net/mpls_* files, they were all blank. I assume that
means that no
  labels have been binded yet? I don't really know why.

   I will greatly appreciate any advice from you or anyone else who can
help. Have been stuck at this for some time.

    BTW, has anyone come up with a more complete/reliable implementation of
LDP, that may also support ATM LSRs?

   Thanks a lot in advance.

Regards,

Paul
