In intra-domain MPLS VPN networks, data packets will be encapsulated with two layers of MPLS when they enter the public network and are forwarded.Label, a description of the two-layer label in the following options. What is wrong is:

M PLS VPNThe outer layer is labeled as a private network label, and the inner layer label is called a public network label.

Layer labels are used inPEThe device sends the packet correctly to the correspondingVPNmiddle

MPLS VPNThe outer label is made byLDPprotocol or statically assigneD. the inner label is assigned by the correct end MP-BGPassigned by neighbors

By default, the outer label is popped before the packet is forwarded to the last hop device

Created by assigning labels staticallyLSPIt can also be dynamically adjusted according to changes in network topology, without administrator intervention. pre

The principle to be followed when manually assigning labels is: the value of the outgoing label of the upstream node is the value of the incoming label of the downstream node
