when a protected LSP had a failure and now the bypass is in use - what should the ingress do when he gets the news about the failure?
 
if it can't find alternative path for tha protected LSP - should it shut the protected LSP???
should it shut it after some timeout? say 3 minutes ?
 

Your question is an implementation question. You should see with your vendor.
A possible implementation is:
- when the head-end receives the Path Error "Tunnel locally repaired", it can trigger a reoptimization,
- if the TE LSP cannot be reoptimized, the head-end can still use the TE LSP without shutting it down.
