Which type of VPN involves the forwarding of traffic over the backbone through the use of labels distributed among core routers?

  • MPLS VPN
  • GRE over IPsec
  • IPsec virtual tunnel interface
  • dynamic multipoint VPN

Explanation: Multiprotocol Label Switching (MPLS) is used by service providers in their core networks to forward traffic through the MPLS backbone. This process involves the use of labels that are previously distributed among the core routers to determine the next hop for a packet. This mechanism allows the provider to create secure, virtual paths between client sites that effectively segregate their traffic from other customers.
