Description (partial)

Symptom:MPLS bindings advertized from the remote neighbors don't expire after loosing all neighbors. 

This is harmless in most cases. This is because as soon as the router gets a new neighbor that does not have the same ldp binding, than these ldp bindings expire. If the router gets an old neighbor back then the old labels that were used before are used. 

Conditions:Router loosing all of it's neighbors can happen when you shut down all MPLS interfaces.
