Thanks for your answer, but I still have the same problem. See the logs below.

Hmm, I tried it with a /32 static route to the router but I could net get the 

(on each host, I run first zebra -d with the enclosed configuration that has 
a static /32 route to router ID, then mpldadm -L eth0:0, then ldp_linux)
