The three major components of Cisco network virtualization are:

  1. Path Isolation: Path isolation ensures that traffic between virtual networks remains separate and secure. It involves creating virtual pathways that are independent of each other, which enables each virtual network to have its own isolated forwarding path. Path isolation is accomplished through various technologies such as VLANs, VXLANs, and network segmentation.

  2. Virtual Network Services: Virtual network services are the tools and applications that are used to provide various network services such as firewalls, load balancers, VPNs, and intrusion detection and prevention systems (IDS/IPS) to virtual networks. These services can be deployed in a virtualized environment to provide the same level of security and functionality as traditional network services.

  3. Policy Enforcement: Policy enforcement refers to the ability to enforce policies and rules across the virtual network infrastructure. It involves applying rules and policies to virtual networks to ensure compliance with security, regulatory, and other requirements. Policy enforcement can be achieved through various tools such as firewalls, access control lists (ACLs), and quality of service (QoS) policies.

  4. Network Access Control: While not one of the three major components, Network Access Control (NAC) is another important aspect of Cisco network virtualization. NAC ensures that only authorized users and devices are allowed to access the network. It involves various technologies such as 802.1x authentication, MAC address filtering, and network segmentation. NAC helps to prevent unauthorized access to the network and ensures that only authorized users and devices are allowed to access network resources.
