（1）拓扑图

（2）配置

R2:
ipv6
dhcp enable

interface GigabitEthernet0/0/0
 ipv6 enable
 ipv6 address 192:168:1::1/96
 dhcpv6 relay destination 172::200
#
interface GigabitEthernet0/0/1
 ipv6 enable
 ipv6 address 201::2/96
 
ipv6 route-static :: 0 201::1


R1-dhcp server:
ipv6
dhcp enable
#
dhcpv6 pool pool192
 address prefix 192:168:1::/96
 excluded-address 192:168:1::1 to 192:168:1::99
 dns-server 1:1::1
 dns-server 1:1::2
 
interface GigabitEthernet0/0/0
 ipv6 enable
 ipv6 address 172::200/16
 dhcpv6 server pool192  #注意，在模拟器中，如果R1的g0/0/0接口不配置此命令，则pc1是获取不到ipv6地址的。

ipv6 route-static :: 0 172::1

sw1:
ipv6
interface Vlanif200
 ipv6 enable
 ipv6 address 200::1/96
#
interface Vlanif201
 ipv6 enable
 ipv6 address 201::1/96

interface GigabitEthernet0/0/1
 port link-type access
 port default vlan 200
#
interface GigabitEthernet0/0/3
 port link-type access
 port default vlan 201
 
ipv6 route-static :: 0 200::2
ipv6 route-static 192:168:1:: 96 201::2

sw2:
ipv6
interface Vlanif172
 ipv6 enable
 ipv6 address 172::1/96
#
interface Vlanif200
 ipv6 enable
 ipv6 address 200::2/96
#
interface MEth0/0/1
#
interface GigabitEthernet0/0/1
 port link-type access
 port default vlan 200
#
interface GigabitEthernet0/0/2
 port link-type access
 port default vlan 172

ipv6 route-static 192:168:1:: 96 200::1
ipv6 route-static 201:: 96 200::1

（3）测试获取ipv6地址：成功

<R1_dhcp_Sever>display dhcpv6 pool pool192 allocated address

抓包：

客户端侦听的UDP端口号是546；服务器、中继侦听的UDP端口号是547。
