Configuring an IPv4-to-IPv6 destination address translation policy
AFT compares an IPv4 packet with IPv4-to-IPv6 destination address translation policies in the following order:
AFT mappings for IPv6 internal servers.
IPv6-to-IPv4 source address static mappings.
IPv4-to-IPv6 destination address dynamic translation policies.
To configure an IPv4-to-IPv6 destination address translation policy:
Step | Command | Remarks |

| By default, no IPv4-to-IPv6 destination address translation policies exist. |
