Configuring An Ipv4-To-Ipv6 Source Address Translation Policy - HPE FlexNetwork HSR6800 Configuration Manual

Step
2. Configure an
IPv4-to-IPv6
destination address
translation policy.
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:
1. IPv4-to-IPv6 source address static mappings.
2. IPv4-to-IPv6 source address dynamic translation policies.
3. The first NAT64 prefix.
To configure an IPv4-to-IPv6 source address translation policy:
Step
1. Enter system view.
2. Configure an
IPv4-to-IPv6 source
address translation
policy.
Command
•
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 ] |
number ipv4-acl-number { prefix-general
prefix-general prefix-length | prefix-ivi prefix-ivi
[ vpn-instance ipv6-vpn-instance-name ] } }
Command
system-view
•
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
415
Remarks
By default, no
IPv4-to-IPv6
destination address
translation policies
exist.
You can use a
nonexistent IVI prefix or
general prefix in a
policy, but the policy
takes effect only after
you configure the
prefix.
Remarks
N/A
By default, no
IPv4-to-IPv6 source
address translation
policies exist.
You can use a
nonexistent NAT64
prefix or general
prefix in a policy, but
the policy takes effect
only after you
configure the prefix.
