MSR G2设备作为DHCPv6服务器为终端分配ipv6地址前缀配置案例

设备都是MSR-G2 版本为V7 Release 0605P21，设备组网如图所示

需要实现需求如下：

1、DHCPv6 client设备GE0/0接口自动获取DHCPv6 server分配的ipv6地址

2、DHCPv6 client设获取DHCPv6 serve分配的地址前缀，并分配给下联终端PC

【DHCPv6-client】

#

interface GigabitEthernet0/0

 port link-mode route

 ipv6 address dhcp-alloc      //配置该接口自动获取ipv6地址，会获取到dhcp pool 1里的地址

 ipv6 dhcp client stateful prefix 1

 ipv6 dhcp client pd 1           //本条命令和上一条命令任意配一条即可，任意一条都可以获取到ipv6前缀

#

interface GigabitEthernet0/1

 port link-mode route

 ipv6 address 1 ::1/64      //获取地址前缀后，引用该前缀生成接口上的ipv6地址，并将此前缀分配给终端

 undo ipv6 nd ra halt

在server上添加回程路由后，可以在终端上ping通server
