I think the patch only works for kernel 2.4.13. Try that, it will work.

I patched the kernel with mpls-linux-1.0, and configured the kernel.
When I reboot with the new complied kernel, I can't find eth0 using =3D
ifconfig.
I can't start up my X windows.:-(

When I was compling the mplsadm, it occure error. it said "linux/mpls.h: =
=3D
no directory or files".
I am surprised. The file exist indeed!!

can anyone answer my question?
Thank u very much~~~

Hi ,

I am new to MPLS and am planning to use the 2684bridged encapsulation to
create interfaces for running mpls over atm.
The example suggests using `atmarp` from the clip package to create the
interface, but is it possible to use the atm interface created by 2684
bridgedPVC patch for atm for MPLS.
Reason being with `atmarp` we can only create one IP interface (i.e.
"atm<no.>") where the "no." depends on itf number of the NIC.
Please correct me if i am wrong.

Thanks in advance.
Regards
Vivek

Subject: [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 st=
eps
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 establish=
ed
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 t=
hat
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
