# Configure the 4to6 AFT policy for destination address translation so that the Router B can

translate the destination address into an IPv6 address by using the IVI prefix (6::) for packets

destined to network 6.6.6.0/24.

# Create ACL 2000 to permit packets from the IPv4 network 4.4.4.0/24, on which Host C resides

(this step is optional).

# Configure the 4to6 AFT policy for source address translation so that the Router B can translate

the source address into an IPv6 address by using the DNS prefix (2000::/32) for packets from

network 4.4.4.0/24 (this step is optional).

[RouterB] aft 4to6 acl number 2000 prefix-dns64 2000:: 32

NOTE:

Configuring the 4to6 AFT policy for source address translation is optional. If the policy is not confi

ured,

FT uses the first confi

ured DNS64 prefix to translate the source IPv4 address into an IPv6 address.

2. Configure Host A:

Perform the following configurations on Host A. (Details not shown.)

{ Configure IPv6 address 6:0:ff06:606:200::/64.

{ Configure a static route to IPv6 network 2000::/32 (the DNS64 prefix) and the next hop

address 6:0:ff06:606:100::.

3. Configure Host C:

Perform the following configurations on Host C. (Details not shown.)

{ Configure IPv4 address 4.4.4.2/24.

{ Configure a static route to the IPv4 network (6.6.6.0/24) embedded in the IVI address and the

next hop address 4.4.4.1.

Verifying the configuration

The IPv4 address embedded in the IPv6 address of Host A is 6.6.6.2. Execute the ping 6.6.6.2

command on Host C. The ping operation should be successful.
