路由器如何与交换机实现拨号PPPOE ipv6上网呢？

路由器如何与交换机实现拨号PPPOE ipv6上网呢？

路由器上配置如下：

dialer-group 6 rule ip permit

dialer-group 6 rule ipv6 permit

interface Dialer 6

ppp chap password si xxx

ppp chap user xxxx

ppp pap local-user xxx password si  xxx

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

interface GigabitEthernet0/0

 port link-mode route

 combo enable copper

 pppoe-client dial-bundle-number 6

interface GigabitEthernet0/4

 ip address 192.168.100.1 255.255.255.0

 dhcp server apply ip-pool 100

 ipv6 dhcp select server

 ipv6 dhcp server apply pool 1

 ipv6 address 1 ::1/64

 ipv6 nd autoconfig managed-address-flag

 ipv6 nd autoconfig other-flag

 undo ipv6 nd ra halt

ip route-static 0.0.0.0 0 Dialer6

ipv6 route-static :: 0 Dialer6

[H3C]disp ipv6 dhcp option-group DHCPv6 option group: 1 DNS server addresses: Type: Dynamic (DHCPv6 prefix allocation) Interface: Dialer6 240E:56:4000:8000::69 240E:56:4000::218

[H3C]display ipv6 prefix Number Prefix Type 1 240E:39B:F18:B240::/60 Dynamic 

剩下的交换机与路由器就不知道怎么配置了。ipv4知道怎么配置，这个IPV6在交换机与路由器就不知道怎么配置了
