31. Cisco NAT-PT Configuration Example

Cisco 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.

27. IPv6 over IPv4 ISATAP Tunneling

ISATAP 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.
