Question 26 of 33

27. Which of the following statements is wrong?

In the MPLS VPNE connection model, the network consists of the operator's backbone network and the user's various sites. The so-called VPN is the division of a set of sites. One VPN corresponds to a set of several sites.

The network construction of MPLS VPN is completed by the service provider. In this network construction, the service provider provides VPN services to users, and users do not feel the existence of the public network, as if they have independent network resources.

The backbone routers within the service provider's backbone network, that is, the routers that are not directly connected to the edge routers, are unaware of the existence of the VPN and are only responsible for data transmission within the backbone network.

All VPN construction, connection and management are performed on backbone routers.
