  B. The label space 1024 and higher is shared by dynamic signaling protocols, such as LDP, RSVP-TE, and MP-BGP.
  C. When the last hop receives packets with the label control 0, it directly performs IP forwarding or forwards the packets based on the next-layer label.
  D. When the penultimate-hop LSR performs label switching, if it finds that the label value after the switching is 3, then it pops out the label and sends the packet to the last hop.

• Question 168:

  Which of the following statements regarding VRRP is false?

  A. VRRP determines the device role in the virtual router based on device priorities.
  B. If the backup router works in non-preemption mode, the backup router with a higher priority does not become the master router as long as the master router does not fail.
  C. Even if there is the master router, the backup router will preempt to be the master router.
  D. When two routers with the same priority preempt to be the master router, the IP addresses of interfaces are compared. The router with a larger IP address of the interface is selected as the master router.
