Configuring AFT

Overview

Address Family Translation (AFT) is a technology that translates an IP address of one address family
into an IP address of the other address family. It enables IPv4 network and IPv6 network to
communicate with each other.
As shown in
network. The IPv4 host and the IPv6 host can communicate with each other without changing the
existing configuration.

Compatibility information

Command and hardware compatibility

Commands and descriptions for centralized devices apply to the following routers:
•
MSR1002-4/1003-8S.
•
MSR2003.
•
MSR2004-24/2004-48.
•
MSR3012/3024/3044/3064.
Commands and descriptions for distributed devices apply to MSR4060 and MSR4080 routers.

AFT implementations

Static AFT

Static AFT creates a fixed mapping between an IPv4 address and an IPv6 address.

Dynamic AFT

Dynamic AFT creates a dynamic mapping between an IPv4 address and an IPv6 address.
When dynamic AFT performs IPv6-to-IPv4 source address translation, two modes are available, Not
Port Address Translation (NO-PAT) and Port Address Translation (PAT).
