• Question 4

  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:

  • 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
  • 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
