3. 配置步骤

# 配置接口GigabitEthernet1/0/1和GigabitEthernet1/0/2的IPv6地址。取消设备发布RA消息的抑制。配置被管理地址的配置标志位为1，即主机通过DHCPv6服务器获取IPv6地址。配置其他信息配置标志位为1，即主机通过DHCPv6服务器获取除IPv6地址以外的其他信息

<RouterA> system-view

[RouterA] interface gigabitethernet 1/0/2

[RouterA-GigabitEthernet1/0/1] ipv6 address 2::1 64

[RouterA-GigabitEthernet1/0/1] quit

[RouterA] interface gigabitethernet 1/0/1

[RouterA-GigabitEthernet1/0/1] ipv6 address 1::1 64

[RouterA-GigabitEthernet1/0/1] undo ipv6 nd ra halt

[RouterA-GigabitEthernet1/0/1] ipv6 nd autoconfig managed-address-flag

[RouterA-GigabitEthernet1/0/1] ipv6 nd autoconfig other-flag

# 配置接口GigabitEthernet1/0/1工作在DHCPv6中继模式，并指定DHCPv6服务器地址。

[RouterA-GigabitEthernet1/0/1] ipv6 dhcp select relay

[RouterA-GigabitEthernet1/0/1] ipv6 dhcp relay server-address 2::2

4. 验证配置

# 完成上述配置后，查看DHCPv6中继上指定的DHCPv6服务器地址信息。

[RouterA-GigabitEthernet1/0/1] display ipv6 dhcp relay server-address

Interface: GigabitEthernet1/0/1

 Server address                             Outgoing Interface

 2::2

# 查看DHCPv6中继相关报文的统计信息。

[RouterA-GigabitEthernet1/0/1] display ipv6 dhcp relay statistics
