yes, you got it right: LDP is implemented by Quagga.
Unfortunately, there is no documentation in Netkit about its usage (just a sample configuration file, but is mostly empty), and also the Quagga documentation about LDP is scarce. However, basic usage of LDP should be quite: all you usually need to do is enable ldpd in /etc/zebra/daemons and put lines similar to the following in /etc/zebra/ldpd.conf:
> interface eth0
> mpls ip
Available commands in ldpd can be found by pressing "?" or issuing the "list" command on the ldpd CLI, which is the way I suggest you to go if you want to explore further configurations. Also, respecting Quagga's tradition, most of the commands should be fairly compliant with the standard LDP-related Cisco commands (see, e.g., http://www.cisco.com/c/en/us/td/docs/ios/12_4t/12_4t2/ftldp41.html).
Last, please consider that the MPLS data plane is known to work in Netkit, but the control plane (implemented by Quagga) and its relation with the data plane are much less supported. That is, you may expectedly be able to assign labels using LDP, but it may be quite hard (or even impossible) to instruct the data plane to use those labels for forwarding. This is due to the fact that some parts of the MPLS implementation used in Netkit (and, indeed, of most Linux-based MPLS implementations) are experimental or missing. We welcome any feedback on this.
Feel free to follow up for any further clarifications.
