In the intra-domain MPLS VPN network, when the data packet enters the public network and is forwarded, it will be encapsulated with two layers of MPLS labels.
Which of the following description of the two layers of labels is wrong?

The outer label of MPLS VPN is allocated by the LDP protocol or statically, and the inner label is allocated by the MP-BGP neighbor at the correct end.
The outer label of MPLS VPNE is called the private network label, and the inner label is called the public network label.
By default, the outer label is ejected before the packet is forwarded to the last-hop device
The outer label is used to correctly send the data packet to the corresponding VPN on the PE device

Which of the following statement is wrong?

LSPs established by statically assigning labels can also be dynamically adjusted according to changes in the network topology, without administrator intervention
The principle to be followed for manual label allocation is: the value of the outgoing label of the upstream node is the value of the incoming label of the downstream node
LSP is divided into static LSP and dynamic LSP. The static LSP is manually configured by the administrator, and the dynamic LSP is dynamically established using the label protocol
Dynamic LSP is dynamically established through label distribution protocols, such as MP-BGP, RSVP-TE, LDP
