付费专栏：IPv6组网实战从入门到精通

本举例介绍接口的IPv6地址的配置过程。

组网需求

如图1所示，两台路由器通过POS接口相连，给接口配置IPv6全球单播地址，验证它们之间的互通性。

需要配置的全球单播地址为2001:db8::1/64和2001:db8::2/64。

图1 配置接口的IPv6地址组网图

配置思路

配置接口的IPv6地址思路如下：

使能路由器的IPv6转发能力

配置接口的IPv6全球单播地址

数据准备

为完成此配置例，需准备如下的数据：

接口的全球单播地址

操作步骤

1. 使能路由器的IPv6转发能力

# 配置RouterA。

<HUAWEI> system-view

[HUAWEI] sysname RouterA

[RouterA] ipv6

# 配置RouterB。

<HUAWEI> system-view

[HUAWEI] sysname RouterB

[RouterB] ipv6

2. 配置接口的全球单播地址

# 配置RouterA。

[RouterA] interface pos 1/0/0

[RouterA-Pos1/0/0] ipv6 enable

[RouterA-Pos1/0/0] ipv6 address 2001:db8::1/64

[RouterA-Pos1/0/0] undo shutdown

[RouterA-Pos1/0/0] quit

# 配置RouterB。

[RouterB] interface pos 1/0/0

[RouterB-Pos1/0/0] ipv6 enable

[RouterB-Pos1/0/0] ipv6 address 2001:db8::2/64

[RouterB-Pos1/0/0] undo shutdown

[RouterB-Pos1/0/0] quit

3. 验证配置结果

如果配置成功，可以查看配置的全球单播地址，以及接口状态为Up，IPv6协议状态为Up。

# 显示RouterA的接口信息。

[RouterA] display ipv6 interface pos 1/0/0

Pos1/0/0 current state : UP

IPv6 protocol current state : UP

IPv6 is enabled, link-local address is FE80::C964:0:B8B6:1

# 显示RouterB的接口信息。

[RouterB] display ipv6 interface pos 1/0/0

Pos1/0/0 current state : UP

# 从路由器RouterA上Ping路由器RouterB的链路本地地址，注意需要使用-i参数，来指定链路本地地址的接口。

[RouterA] ping ipv6 fe80::2d6f:0:7af3:1 -i pos 1/0/0
