实战：ipv6有状态自动配置(通过DHCP配置)
1.原理
2.拓扑图
3.配置AR1
<Huawei>sys
[Huawei]ipv6 --全局开启对IPv6的支持
[Huawei]dhcp enable
[Huawei]dhcpv6 duid llt
[Huawei]dhcpv6 pool localnet
[Huawei-dhcpv6-pool-localnet]address prefix 2021:9:20::/64
[Huawei-dhcpv6-pool-localnet]excluded-address 2021:9:20::1
[Huawei-dhcpv6-pool-localnet]dns-domain-name 91xueit.com
[Huawei-dhcpv6-pool-localnet]dns-server 2021:9:20::1
[Huawei-dhcpv6-pool-localnet]quit
[Huawei]interface g0/0/0
[Huawei-GigabitEthernet0/0/0]ipv6 enable --在接口上启用IPv6支持
[Huawei-GigabitEthernet0/0/0]ipv6 address 2021:9:20::1 64 --添加IPv6地址
[Huawei-GigabitEthernet0/0/0]ipv6 address auto link-local --配置自动生成链路本地地址
[Huawei-GigabitEthernet0/0/0]dhcpv6 server localnet
[Huawei-GigabitEthernet0/0/0]undo ipv6 nd ra halt --允许接口发送RA报文，默认不发送RA报文
[Huawei-GigabitEthernet0/0/0]ipv6 nd autoconfig managed-address-flag
[Huawei-GigabitEthernet0/0/0]ipv6 nd autoconfig other-flag
[Huawei-GigabitEthernet0/0/0]quit
4.测试
WIN11，先取消IPV6，再应用
抓包
路由通告里面请求的标记位M和O的标记位为1
WIN11查看配置情况
地址使用情况
display dhcpv6 pool
5.查看接口IPV6设置
[Huawei]display ipv6 neighbors
netsh interface ipv6 show address
