Description (partial)


Under extreme link flapping conditions, MPLS-TE AutoTunnel BackUp may try to 
estabilish a backup via the same path as the primary path


This arises due to OSPF Database having an orphan opaque LSA in its database. 
This information will be passed on to the MPLS-TE and MPLS-TE tries to bring in the 
backup LSP using this incorrect information.
