  A. The LSP will stay on the current path indefinitely unless another failure occurs.
  B. The LSP will stay on the current path until the resignal timer expires.
  C. The LSP will switchover to R1-R2-R3-R5-R6 after the resignal timer expires.
  D. The LSP will switchover to R1-R3-R5-R6 after the retry timer expires.
  D. The LSP will switchover to R1-R3-R5-R6 after the retry timer expires.
