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:
- A. M PLS VPNThe outer layer is labeled as a private network label, and the inner layer label is called a public network label.
- B. MPLS VPNThe outer label is made byLDPprotocol or statically assigneD. the inner label is assigned by the correct end MP-BGPassigned by neighbors
