MSR830用pppoe拨号上网，配置ipv6又遇问题。

之前提问MSR830 pppoe拨号ipv6的问题，固件版本msr800-cmw520-r2516p24，

有大佬给出了答案：

1. 配置拨号接口：
interface Dialer 1
pppoe-client dial-bundle-number 1
ipv6 enable
ipv6 pppoe-client enable // 开启IPv6 PPPoE客户端
2. 绑定物理接口（如公网口G0/0）：
interface GigabitEthernet 0/0
pppoe-client dial-bundle-number 1
3. 内网接口配置IPv6：
interface GigabitEthernet 0/1
ipv6 enable
ipv6 address auto link-local // 或按需配置静态IPv6地址
验证命令：display ipv6 interface Dialer 1（查看拨号获取的IPv6地址）、display pppoe client session（确认拨号状态）。

但配置下来，发现有些命令并不支持，请问该如何解决：

我的配置：
