Chapter 1 Dual Stack Configuration
When configuring dual stack, go to these sections for information you are interested in:
& Note:
The term “router” in this document refers to a router in a generic sense or an Ethernet switch running routing protocols.
1.1 Dual Stack Overview
For an upper layer application supporting both IPv4 and IPv6, either TCP or UDP can be selected at the transport layer, while IPv6 stack is preferred at the network layer.
Figure 1-1 illustrates the IPv4/IPv6 dual stack in relation to the IPv4 stack.

1.2 Configuring Dual Stack
You must enable the IPv6 packet forwarding function before dual stack. Otherwise, the device cannot forward IPv6 packets even if IPv6 addresses are configured for interfaces.
Follow these steps to configure dual stack on a gateway:
|
To do… |
Use the command… |
Remarks |

|
system-view |
— |
|||
|
Enable the IPv6 packet forwarding function |
ipv6 |
Required Disabled by default. |
||
|
Enter interface view |
interface interface-type interface-number |
— |
||
|
Configure an IPv4 address for the interface |
ip address ip-address { mask | mask-length } [ sub ] |
Required By default, no IP address is configured. |
||
|
Configure an IPv6 address on the interface |
Configure IPv6 global unicast address or local address |
Manually specify an IPv6 address |
ipv6 address { ipv6-address prefix-length | ipv6-address/prefix-length } |
Use either command By default, no local address or global unicast address is configured on an interface |
|
Configure an IPv6 address in the EUI-64 format |
ipv6 address ipv6-address/prefix-length eui-64 |
|||
|
Configure IPv6 link-local address |
Automatically create an IPv6 link-local address |
ipv6 address auto link-local |
Optional By default, after you configured an IPv6 local address or global unicast address, a link local address is automatically created. |
|
|
Manually specify an IPv6 link-local address |
ipv6 address ipv6-address link-local |
|||
Caution:
For more information about IPv6 address, refer to IPv6 Basics Configuration in the IP Services Volume.
