sorry, i afraid i was confused too...
of course im using the latest cvs version of the ldp patch for zebra and
zebra + mplsd and latest patch for the linux kernel....

i started with a simple setup, with static routes in zebra.conf and a 
simple mplsd.conf:

hostname LSR-2
password pppp
enable password pppp
!
!
mpls ldp
! trace debug
! trace event
! trace normal
! trace notification
! trace path
! trace policy
! trace state
  egress connected
  address-mode ldp
!
interface lo
!
interface eth1
  mpls ldp
!
interface dummy0
!
interface eth2
  mpls ldp
!
interface eth3
  mpls ldp
!
interface eth0
!
line vty
  exec-timeout 0 0
!


there was ldp traffic, but no label assigns to remote routes...

i can't reproduce this behaviour again, because i changed the setup and 
use now ospfd too (without static routes) :-)
simple setup with to areas:
area 1: 1 2 7 4
area 2: 3 5 6


now i see the label information and can test them with a ping
(dumping it with a modified uml_switch), but there is a other problem:

mpls_in and mpls_out are constantly growing until around 220 and more 
(peak was 682) enries for in and 35 for LER-1 - then they decrease 
rapidly to something about 40...

do you have any ideas why?

which debugging output would be usefull (which config)?

btw: the systems runs very unstable (i use a while true loop for mplsd),
especially LER-7 (i set the two egress routes per script and don't use 
them in zebra,ospfd,mplsd - otherwise it chrashes immediately)


my testsetup:

          .--------LSR_2-----------.
         /              \          |
        /                LSR_5     |
       /                /     \    |   /
      /                /       \   |  /
----LER_1--------LSR_3         LER_7
      \                \       /   |  \
       \                \     /    |   \
        \                LSR_6     |
         \              /          |
          '--------LSR_4-----------'

     |----------- MPLS ------------|
