通过PPPoE链路的ASA5505和IPv6

我看到许多关于Cisco ASA（在本例中为5505）是否可以通过PPPoE连接使用IPv6的相互冲突的信息。

我看到了正式的Cisco文档，使它看起来很容易，但我看到了很多的论坛帖子中指出它无法正常工作。

这可能吗？


我们的提供者是Internode；并且提供了在800系列路由器上启用的本指南。我们ASA的/56的开头是：

关于我尝试过的内容：我尝试为连接启用自动配置，我添加了PD进入ASA，但是由于实际的PPPoE链路需要动态IP，因此无法设置静态IP。无论如何，我还是尝试过（通过使用sh ver，它似乎是Internode的一种常见配置），但是从内存中，ASA不会让我仅将路由分配给接口，它只需要下一跳，而我没有
