• Question 171:

  A fully loose LSP MtoR6" is enabled with FRR protection. All links have the same cost. After the link between R2 and R4 goes down, FRR protection repairs the LSP and traffic traverses on R1-R2-R7-R8-R4- R6. By default, which of the following about this LSP on an Alcatel-Lucent 7750 SR is FALSE?

  A. The LSP will switch to R1-R3-R5-R6 after the resignal timer expires.
  B. The old primary path and its detours are torn down after the new primary path is established.
  C. CSPF must be enabled to find a more optimal path.
  D. The traffic is switched to R1-R3-R5-R6 in an MBB fashion.
  A. The LSP will switch to R1-R3-R5-R6 after the resignal timer expires.
