Usage Guidelines

The NAT64 prefix must be different from the IPv6 interface address prefix.

This command is used to configure the global NAT64 prefix. If no specified global NAT64 prefix is available, the well known prefix 64:FF9B::/96 takes effect by default.

Example

# Set the NAT64 prefix to 2001::/32.

<sysname> system-view
[sysname] nat64 prefix 2001:: 32
