Re: [mpls-linux-devel] MPLS & linux kernel 2.6.16.2

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
