Regarding the label space of MPLS, which of the description is wrong?

1. A. When the penultimate hop LSR performs label switching, if the value of the label after the exchange is found to be 3, the label will be ejected by default and the packet will be sent to the last hop
2. B. 1024 or more is the label space shared by dynamic signaling protocols such as LDP, RSVP-TE, MP-BGP, etc.
3. C. 16~1023 is the label space shared by static LSP and static CR-LSP
4. D. If the outgoing label value is 0, the router will directly discard the packet — đáp án hiện tại
