Hi Mr. Leu, hi everybody,
I'm a Computer Software Engineer student and I'm developing my dissertation
on Load Balancing with MPLS routing.
I'm trying to use the version 1.950 of the MPLS routing, but I'm facing some
configuration problem after compiling the patch from the sources; I kindly
ask you to help me in this phase.
I'm using a Debian distribution with the following items:
* Linux kernel v. 2.6.16.2
* iproute2-2.6.16-060323
* iptables-1.3.5
* ebtables-v2.0.8-rc2
* quagga-0.99.4
and, of course, mpls-linux-1.950.
I applied the patches to the kernel in the indicated order; I found some
rejections (.rej), but I "easily" solved them by hands by slightly modifying
the source code (adding header files, removing ".owner"...)
My configuration correctly shows the MPLS module as present; I compiled with
no error and installed the new MPLS-powered kernel.
Despite that, on invoking any MPLS operation (like mpls add nhlfe 0...). I
get this message:
RTNETLINK answers: invalid argument
I'm sure that I'm missing something tremendously obvious!
In the following, the systrace output for "mpls nhlfe add key 0" - hope it
helps.
Thank you in advance for any help.
Best regards,
Marina Mariano
systrace begins....

Hello Marina,
Did you compile MPLS as a module? Did you include IPv4 bindings for MPLS?
Did you load the mpls4 module?

Hi James,
actually I compiled MPLS as a part of the kernel, not as a Module (by
chosing Yes in .config). I tried also to compile and load it as a separate
module but it didn't work.
I also loaded as separate modules mpls4 and ipt_mpls.
Is that enough to include IPv4 binding or I'm still missing something??
Thanks a lot for your precious information,
Marina

I'm not sure having MPLS compiled in and mpls4 as a module will work
(I've never tried it). If your going to compile MPLS into the kernel you
probably should compile mpls4 in as well. ipt_mpls is not needed
unless your going to use iptables to map traffic onto LSPs. mpls and mpls4
allow for using the iproute2 commands to map traffic onto a LSP.
BTW if your interested in contributing your research back to the project
I might have some suggestions as to where you should hook into the
mpls stack.
