Just added an additional redundant link between 2 MT Routers. Still needs to disable/enable LDP on one of the routers to make the IPs of this link reachable. So I have to make an interrupt to several hundret people to make this work. Disabling/Enabling of the (LDP)interface does not help. I have to completely interrupt MPLS flowing through this routers.
So MPLS does not heal itself from a bad state. Needs to be kicked.
Using 6.47.10 everywhere.
