[j-nsp] MX5-T logical-routers question

Hello,

 I am trying to test some features with an MX5-T router with
logical-systems but my results are below expectations and I don't
understand what's wrong.
The topology and the config are very simple: R1 --- R2 ---R3 :

While a ping from R1 loopback to R3 loopback is successful , a traceroute
from R1 to R3 doesn't show the transit router R2 (I tried with and without
mpls), and a lsp from R1 to R3 is failing to come up.
