msr830(v7) 拨号上网 ipv6无法访问。

msr830(v7) 拨号上网。ipv4网络正常。  ipv6网络不能访问外网。 vlan内部各地址能ping 通，但ping不了 Dialer1接口的ipv6地址。 Dialer1接口可以ping通 外网地址。

感觉是路由表出了问题，但不知道怎么配置才对，或者是Dialer1接口和vlan并没有在同一本地链路中。如何才能让他们同在一个网段内。

关于ipv6在路由器上的配置如下：

#

ipv6 dhcp pool 1

option-group 1

#

interface Dialer1

ipv6 address auto

ipv6 address auto link-local

ipv6 dhcp client pd 1 option-group 1

ipv6 dhcp client stateless enable

#

interface Vlan-interface1

ipv6 dhcp select server

ipv6 dhcp server apply pool 1 allow-hint preference 255 rapid-commit

ipv6 address 1 ::1/64

ipv6 nd autoconfig managed-address-flag

ipv6 nd autoconfig other-flag

undo ipv6 nd ra halt
