本举例介绍IPv6邻居发现的配置过程。

组网需求

如图1所示，路由器通过接口GE1/0/10和PC相连，PC操作系统为WindowsXP。

图1 配置IPv6邻居发现示例

配置思路

采用如下的思路配置IPv6邻居发现：

在接口GE1/0/10上配置链路本地单播地址和EUI-64（Extended User Interface Server）站点本地单播地址。

在接口GE1/0/10上配置需要发布的RA（Router Advertisement）前缀消息并打开RA消息的发布开关。

数据准备

完成此配置，需准备如下的数据：

接口的链路本地单播地址和EUI-64站点本地单播地址

需要发布的RA前缀消息

操作步骤

1. 使能路由器的IPv6转发能力

<HUAWEI> system-view

[HUAWEI] ipv6

1. 配置接口的链路本地单播地址

[HUAWEI] interface gigabitethernet 1/0/10

[HUAWEI-GigabitEthernet1/0/10] undo shutdown

[HUAWEI-GigabitEthernet1/0/10] ipv6 enable

[HUAWEI-GigabitEthernet1/0/10] ipv6 address auto link-local

1. 配置接口的EUI-64站点本地单播地址和RA消息中的前缀

在路由器上配置需要发布的RA前缀消息并打开RA消息的发布开关后，PC才能自动获得路由器RA报文的地址前缀消息。

[HUAWEI-GigabitEthernet1/0/10] ipv6 address 2001:db8::/64 eui-64

[HUAWEI-GigabitEthernet1/0/10] ipv6 nd ra prefix 2001:db8::/64 1000 1000

[HUAWEI-GigabitEthernet1/0/10] undo ipv6 nd ra halt

1. 验证配置结果

如果配置成功，可以查看配置的链路本地单播地址和EUI-64站点本地单播地址，以及接口状态为Up，IPv6协议状态为Up。
