一、组网需求
Host A和Host B可以通过IPv6地址进行通信。
二、组网图
三、配置要点
在接口上开启IPv6协议，并配置IPv6地址。
四、 配置步骤
(1) 配置Device A
# 配置接口GigabitEthernet 0/1的IPv6地址，并允许在该接口上发送RA报文。
DeviceA> enable
DeviceA# configure terminal
DeviceA(config)# interface gigabitethernet 0/1
DeviceA(config-if-GigabitEthernet 0/1)# ipv6 enable
DeviceA(config-if-GigabitEthernet 0/1)# ipv6 address 1000::1/64
DeviceA(config-if-GigabitEthernet 0/1)# no ipv6 nd suppress-ra
DeviceA(config-if-GigabitEthernet 0/1)# exit
# 配置接口GigabitEthernet 0/2的IPv6地址，并允许在该接口上发送RA报文。
DeviceA(config)# interface gigabitethernet 0/2
DeviceA(config-if-GigabitEthernet 0/2)# ipv6 enable
DeviceA(config-if-GigabitEthernet 0/2)# ipv6 address 2000::1/64
DeviceA(config-if-GigabitEthernet 0/1)# no ipv6 nd suppress-ra
DeviceA(config-if-GigabitEthernet 0/2)# exit
(2) 配置主机
# 配置Host A的IPv6地址为1000::2/24。
# 配置Host B的IPv6地址为2000::2/24。
五、 验证配置结果
# 使用show ipv6 interface可以看到接口添加IPv6地址成功。
DeviceA# show ipv6 interface
