Remote Site Connectivity:

  • Multiprotocol Label Switching (MPLS)is used by service providers and enterprise networks to segment traffic based on an MPLS label rather than an IP address.
  • Tunnel-Based Virtual Private Networks
    • Generic Routing Encapsulation (GRE)
    • Dynamic Multipoint VPN (DMVPN)
    • Multipoint GRE
    • IPsec

  • IPsec
    • DMPVPN uses the benefits of IPsec tunnels in the following 4 ways:
      • ConfidentialityData is being protected by using some form of encryption
      • IntegrityData has not been altered or changed
      • AuthenticationData is visible to authorized users
      • AntireplayData is not being duplicated

Summary:

In summary, their are various ways to segment networks and keep them private. With the growing need of site to site VPNs, technologies such as MPLS, DMVPN, IPsec are a few popular options that make this possible.
