Parameters
ivi-prefix: Specifies the IVI prefix of an IPv6 address.
Usage guidelines
The length of an IVI prefix is 32 bits. If an IPv6 address matches the specified IVI prefix format, AFT
extracts the IPv4 address embedded in the IPv6 address to translate the IPv6 address into an IPv4
address.
The DNS64 prefix cannot be the same as the IVI prefix. Otherwise, an IPv6 host cannot communicate
with another IPv6 host whose address has an IVI prefix the AFT device performs address translation for
the packet and send it to the IPv4 network.
Examples
# Specify the IVI prefix as 3000:db8e::.
<Sysname> system-view
[Sysname] aft prefix-ivi 3000:db8e::
