Configuring An Ipv4-To-Ipv6 Destination Address Translation Policy - HPE FlexNetwork MSR Series Comware 7 Layer 3 - Ip Services Configuration Manuals

Step
5. Configure an
IPv6-to-IPv4 source
address translation policy.
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:
1. AFT mappings for IPv6 internal servers.
2. IPv6-to-IPv4 source address static mappings.
3. IPv4-to-IPv6 destination address dynamic translation policies.
To configure an IPv4-to-IPv6 destination address translation policy:
Step
1. Enter system view.
2. Configure an
IPv4-to-IPv6
destination address
translation policy.
Command
•
Configure an IPv6-to-IPv4 source
address static mapping:
aft v6tov4 source ipv6-address
[ vpn-instance
ipv6-vpn-instance-name ] ipv4-address
[ vpn-instance
ipv4-vpn-instance-name ]
•
Configure an IPv6-to-IPv4 source
address dynamic translation policy:
aft v6tov4 source { acl ipv6 { name
ipv6-acl-name | number
ipv6-acl-number } | prefix-nat64
prefix-nat64 prefix-length [ vpn-instance
ipv6--vpn-instance-name ] }
{ address-group group-id [ no-pat |
port-block-size blocksize ] | interface
interface-type interface-number }
[ vpn-instance
ipv4-vpn-instance-name ]
•
Configure a general prefix:
aft prefix-general prefix-general
prefix-length
•
Configure an IVI prefix:
aft prefix-ivi prefix-ivi
Command
system-view
•
Configure an AFT mapping for an IPv6 internal
server:
aft v6server protocol protocol-type
ipv4-destination-address ipv4-port-number
[ vpn-instance ipv4-vpn-instance-name ]
ipv6-destination-address ipv6-port-number
[ vpn-instance ipv6-vpn-instance-name ]
•
Configure an IPv6-to-IPv4 source address static
mapping:
aft v6tov4 source ipv6-address [ vpn-instance
ipv6-vpn-instance-name ] ipv4-address
[ vpn-instance ipv4-vpn-instance-name ]
•
Configure an IPv4-to-IPv6 destination address
dynamic translation policy:
aft v4tov6 destination acl { name
ipv4-acl-name prefix-ivi prefix-ivi
[ vpn-instance ipv6-vpn-instance-name ] |
