問題1

Which of the following statements regarding MPLS label space is false?

A. The label space 1024 and higher is shared by dynamic signaling protocols, such as LDP, RSVP-TE, and MP-BGP.

B. 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.

C. 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.
