Peter,
what happens after a restart routing is the following:

inet.3: 45 destinations, 45 routes (45 active, 0 holddown, 0 hidden)
+ = Active Route, - = Last Active, * = Both

first I have 45 routes (but the one to the RR is missing(!) It has ip
217.24.235.15. All other MPLS speakers are listed!
Then at some point of time, 2 or three minutes after the restart all but
the 10 listet routes above disappear.

Do you have any idea where I can see what really happens?

Btw. I do have a Label to my RouteReflector (which is by the way a Cisco
7301)
root at juni> show ldp database | match 217.24.235.15
     74     217.24.235.15/32
