Hi:

This is what I tried. I launch only zebra and ldpd on both LSRs and I =
specify the routes for PE1 to reach 13.1 and for PE2 to 12.1:

                  eth0   eth1             eth1   eth0
       12.0.0.1-------PE1---------------------PE2-------13.0.0.1
                         .1  10.0.0.0/24    .2

As you could see the label 10000 is distributed correctly, but the =
routes are created only in vtysh with that label. Although nhlfe and ilm =
are updated, the mpls route doesn't appear.

Thanks in advance,

Gonzalo.
