You need to have the mpls4 module loaded at a minimum.  On Fedora 8 I
use the modules system to load it at boot time for my by creating:

    /etc/sysconfig/modules/mpls-linux.modules

with the contents of:

    #!/bin/sh
    modprobe mpls4

Make sure to make the file executable

I'm assuming your running Fedora 8 and want to use yum to install
mpls-linux RPMs.  Make sure your don't already have a newer kernel.
2.6.24.3-12 was release last week and I have not produced a mpls-linux
version of it yet.  Also make sure you have a
/etc/yum.repos.d/mpls-linux.repo file
