我正在尝试配置 Cisco 678，因为我的 Actiontec 已经让我厌烦透顶了。但是，我遇到了一些问题。看起来 Cisco 能够训练线路，但我无法 ping 通。
这几乎就像我没有正确配置设备以使用 PPPoA（如我的 Actiontec）获取其 IP。来自“show running”的输出（如下）也让我这么认为。
下面是我为了配置此功能而运行的命令：
# en
# set nvram erase
# write
# reboot
# en
# set nat enable
# set dhcp server enable
# set PPP wan0-0 ipcp 0.0.0.0
# set ppp wan0-0 dns 0.0.0.0
# set PPP wan0-0 login xxxxx // My actual login
# set PPP wan0-0 password yyyyy // My actual password
# set PPP restart enabled
# set int wan0-0 close
# set int wan0-0 vpi 0
# set int wan0-0 vci 32
# set int wan0-0 open
# write
# reboot
以下是一些我认为可以提供有用信息的命令的输出：
cbos#ping 74.125.224.113
