3.3 Configuring an IPv6 Address for an Interface

Assigning an IPv6 address to a device on a network enables the device to communicate with the
other devices on the network.

3.3.1 Establishing the Configuration Task

This section describes the applicable environment, pre-configuration tasks, data preparation, and
configuration procedure for assigning an IPv6 address to an interface.
Applicable Environment
When a device communicates with an IPv6 device, you need to configure IPv6 address for the
interface. The AR150/200 supports configuring IPv6 addresses for the following interfaces:
l

l
You can configure 10 addresses for one interface. Addresses can be the link-local address and
the global unicast address.
The link-local address is used in ND, and in the communication between nodes on the local link
in the stateless address auto-configuration. The packets using the link-local address as the source
or destination address are not forwarded to other links.
The link-local address can be automatically generated or manually configured. After being
enable with automatic address generation capability, the system automatically generates a link-
local address. The link-local address configured manually must be a valid link-local address
(FE80::/10).

Prefix length: indicates the length of the destination address prefix. From the prefix length,
you can infer that the destination address is a network address or a host address.
Nexthop: indicates the address of the close next hop through which the packet reaches the
destination.
Flag(s): identifies route features.
Interface: indicates the outgoing interface of the packet.
Timestamp: Indicates the time when an FIB entry is established.
Tunnel ID: Indicates the ID of VPN Tunnel.
NOTE
The IPv6 function is used with a license. To use the IPv6 function, apply for and purchase the following
license from the Huawei local office:
