Re: [mpls-linux-general] MPLS Kernel Loading problem

Hello,

The part about installing the kernel sources + compiling the kernel is
correct, but to actually use MPLS, you'll need at least the patched iproute
package!

I recommend you install iproute and iptables depending on the experiments
you plan to do. The iproute package provides the mpls command which allows
you to build static label paths.

If you want to use LDP, you need to install quagga from the svn repository
(but It might depend on the existence of the mpls command - I'm not sure -
James, correct me if I'm wrong).

Good luck!
