Cisco pyATS (Python Automated Test System) alongside Genie forms a powerful network automation framework that complements both CLI-based and YANG-based automation tools. In this lesson, we will explore the capabilities of pyATS and Genie to understand how they enhance network testing and automation.
DetailsNAT64 is a scalable and modern replacement for NAT-PT, primarily used to enable IPv6 clients to communicate with IPv4 servers. It is commonly deployed alongside DNS64 to facilitate seamless communication through domain names. In this section, we will demonstrate an example of Cisco Stateful NAT64 configuration.
DetailsNAT-PT V4-Mapped V4V6 Translation enables all IPv4 addresses from the internet to be dynamically translated into IPv6 addresses within our network using a NAT-PT IPv6 /96 prefix, without requiring manual configuration. This process will be the focus of our discussion and demonstration in this lesson.
DetailsCisco NAT-PT is part of IPv6 transition technologies that enable communication between IPv4 and IPv6 networks. While deprecated and replaced by NAT64 and DNS64, understanding NAT-PT remains important. In this lesson, I will implement a NAT-PT configuration example using static NAT-PT, with dynamic and PAT versions covered in the following lessons. We will then explore NAT64 and DNS64, which address NAT-PT’s limitations and offer more efficient solutions for IPv4-IPv6 communication.
DetailsThe 6PE solution allows IPv6 traffic to traverse an existing IPv4 MPLS network without requiring the MPLS core to support IPv6 natively. In this section, we will explain the underlying mechanics of 6PE and provide a Cisco-based configuration example to demonstrate its implementation in a practical, real-world scenario.
Details6RD Tunnel is a transition solution for service providers, enabling them to offer IPv6 connectivity over an IPv4 infrastructure while leveraging the ISP’s own IPv6 prefix. This approach facilitates IPv6 deployment without requiring immediate upgrades to the existing network infrastructure.
DetailsISATAP tunneling is an IPv6 migration mechanism that enables IPv6 communication over an IPv4-only infrastructure. It is specifically designed to establish IPv6 communication between endpoints, unlike 6to4, which facilitates IPv6 communication between sites. While ISATAP, like 6to4, is largely considered obsolete today, studying it can still provide valuable insights into multipoint dynamic VPN solutions.
