Description (partial)


OSPF uses ldp-idp out-of-sync tunnel for forwarding resulting in potential traffic blackholing


The test-case: 

The key is that before this config, the tunnel should be used as a next hop
based on the tunnel update from TE.
and the tunnel should not be configured under LDP as yet.

       interface tunnel-te100 (optional)
