msr3620路由器配置ipv6 pppoe +交换机上网？

如何实现ipv6 pppoe拨号上网，在路由器上已经配置好ipv6 拨号，不知道交换机上如何配置？

路由器：

ipv6 dhcp pool 1

option-group 1

dialer-group 6 rule ip permit

dialer-group 6 rule ipv6 permit

interface Dialer 6

ppp chap password si xxxx

ppp chap user xxxxx

ppp pap local-user xxxx password si  xxxxx

ppp ipcp dns admit-any

 ppp ipcp dns request

dialer bundle enable

dialer timer idle 0

dialer timer autodial 10

ip address ppp-negotiate

nat outbound

dialer-group 6

ipv6 address auto

ipv6 address auto link-local

ipv6 dhcp client pd 1 rapid-commit option-group 1

dhcp enable

ip route-static 0.0.0.0 0 Dialer6

ipv6 route-static :: 0 Dialer6

interface GigabitEthernet0/4

 port link-mode route

 description LAN-interface

 ip address 192.168.66.1 255.255.255.0

交换机：

interface Vlan-interface1

 ip address 192.168.66.2 255.255.255.0

 dhcp server apply ip-pool 66

dhcp server ip-pool 72

 gateway-list 192.168.72.1

 network 192.168.72.0 mask 255.255.255.0

 dns-list 61.139.2.69 114.114.114.114

 expired unlimited

dhcp server ip-pool 88

 gateway-list 192.168.88.1

 network 192.168.88.0 mask 255.255.255.0

 dns-list 61.139.2.69 114.114.114.114

 expired unlimited

dhcp server ip-pool 89

 gateway-list 192.168.89.1

 network 192.168.89.0 mask 255.255.255.0

 dns-list 61.139.2.69 114.114.114.114

 expired unlimited

interface Vlan-interface72

 mtu 1492      

 ip address 192.168.72.1 255.255.255.0 

 dhcp server apply ip-pool 72 

#              

interface Vlan-interface88

 ip address 192.168.88.1 255.255.255.0

 dhcp server apply ip-pool 88

#              

interface Vlan-interface89

 ip address 192.168.89.1 255.255.255.0

 dhcp server apply ip-pool 89

 ip route-static 0.0.0.0 0 192.168.66.1

现ipv4可以上网，但不知道ipv6怎么配置，可以实现IPV6上网。
