I usually see this behavior if I've forgotten to load the mpls4 module.
Did you do a 'modprobe mpls4' before starting ldpd?

ooting the system that I solved by typing "enforcing=3D0" at grub.conf. I h=
ave some problems with the wheel of the mouse or the USB ports but in gener=
al it works right. I'm able to create MPLS static configurations. In this v=
ersion the "mpls" module has disappeared so I only load "mpls4". I launch z=
ebra, ospfd and ldpd but I make the whole configuration by vtysh. OSPF work=
s well but I can't put most of the ldpd commands, in fact, the only one tha=
t appears with "show running-config" is "mpls labelspace 0" in the correspo=
nding interface, Neither "mpls ldp" nor "mpls ip". Are these problems solve=
d in FC5? If that's it I would like to work with FC5.
