AFT translates the address into an IPv6 address by using the first configured DNS64 prefix in system
view.
• Policy for destination IPv4 address translation—If the destination IPv4 address matches the
specified ACL, the AFT translates the address into an IPv6 address by using the specified IVI prefix.
If not, the address is not translated and the packet is forwarded according to the destination IPv4
address.
To configure 4to6 AFT policy:

Command Remarks

2. Configure the 4to6 AFT policy
for source address translation.
aft v4tov6 acl number acl-number prefix-dns64
dns64-prefix prefix-length
Optional.
3. Configure the 4to6 AFT policy
for destination address
translation.
aft v4tov6 acl number acl-number prefix-ivi
ivi-prefix
N/A
The DNS64 and IVI prefixes must be those configured by the aft prefix-dns64 and aft prefix-ivi
commands.
With the DNS64 function, the AFT translates the IPv4 address resolved by the DNS server into an IPv6
address by using the DNS64 prefix specified in the 4to6 AFT policy for source address translation.
To configure a 4to6 AFT policy for destination IPv4 address translation, you must configure the ACL to
match the destination addresses of packets, but this requirement is not needed when you configure a
4to6 AFT policy for source IPv4 address translation.
For more information about ACL, see ACL and QoS Configuration Guide.
