DHCPV6配置流程
DHCP SERVER
1）配置地址池
dhcpv6 pool pool1
address prefix 2023:10::/64 //定义前缀
excluded-address 2023:10::1 //排除地址
2）接口调用dhcpv6地址池
interface GigabitEthernet0/0/1
ipv6 enable
ipv6 address 2023:10::1/64
ipv6 address auto link-local //配置LLA地址，本链路通信，不能跳转（单播）
undo ipv6 nd ra halt
dhcpv6 server pool1
DHCPV6 client端
3)申请DHCPV6地址
interface GigabitEthernet0/0/0
ipv6 enable
ipv6 address auto link-local //配置LLA地址，本链路通信，不能跳转（单播）
ipv6 address auto global default //配置默认路由
undo ipv6 nd ra halt
ipv6 address auto dhcp //自动获取IPV6地址
