Configuring an IPv4-to-IPv6 source address translation policy
AFT compares an IPv4 packet with IPv4-to-IPv6 source address translation policies in the following order:
IPv4-to-IPv6 source address static mappings.
IPv4-to-IPv6 source address dynamic translation policies.
The first NAT64 prefix.
To configure an IPv4-to-IPv6 source address translation policy:
Step | Command | Remarks |
|---|
1. Enter system view. | system-view | N/A |
2. Configure an IPv4-to-IPv6 source address translation policy. | Configure an IPv4-to-IPv6 source address static mapping:aft v4tov6 source ipv4-address [ vpn-instance ipv4-vpn-instance-name ] ipv6-address [ vpn-instance ipv6-vpn-instance-name ] Configure an IPv4-to-IPv6 source address dynamic translation policy:aft v4tov6 source acl { name ipv4-acl-name prefix-nat64 prefix-nat64 prefix-length [ vpn-instance ipv6-vpn-instance-name ] | number ipv4-acl-number { prefix-general prefix-general prefix-length | prefix-nat64 prefix-nat64 prefix-length [ vpn-instance ipv6-vpn-instance-name ] } } Configure a NAT64 prefix:aft prefix-nat64 prefix-nat64 prefix-length
| By default, no IPv4-to-IPv6 source address translation policies exist. |
