I'm having difficulties to understand your problem: you have a OSPF
network, that works fine without MPLS. You state that you can get the
LSA header: which ones ? all the area/network ?

This is what I don't understand. The OSPF daemons establish an adjacency
between them, they exchange the link state databae, but you cannot ping
them?

* Where does MPLS fit in all this? Are you trying to establish an
adjacency between routers using an LSP as a Forwarding Adjacency?
(although you should not do that)

* Which LSPs do you want to establish ?

* How are you classifying/filtering the traffic? Which ip rules did you
enable ?


Can you describe your topology a little more ? and what you plan to do ? I
cannot fit this with your original problem of calculating paths from link
state info.

Did you make sure that you compiled zebra using the kernel headers that
were patched for MPLS ?

Can you at least set a LSP manually between routers ?

Withour more info, I would say that maybe you did not compile the last
vesion of zebra with the right ldp patch and using the patched kernel
headers.... Did you have a reject when patching?
