Given the show command results and the configuration shown:
Why did the head end router fail to protect the Label Switch Path (LSP) between POC3-1 and POC3-2 with the configured manual bypass tunnel?

  • A. The protected LSP must specify manual bypass required
  • B. The bypass tunnel path must explicitly specify each hop to the tail end
  • C. The manual bypass LSP must terminate on the bypass path last hop entry
  • D. The protected LSP must specify fast reroute facility


Answer : D

Given the show command results and the configuration shown:
Why did the head end router choose to protect the Label Switch Patti (LSP) with a dynamic bypass tunnel instead of the manual bypass tunnel as configured?

  • A. Manual bypass tunnels must be configured for fast reroute facility and cspf
  • B. The bypass tunnel path's first hop must avoid the protected LSP tail end
  • C. The protected LSP needs a strict hop path to the tail end router
