2621(config)#vpdn enable

!--- Enters VPDN group configuration mode for the specified VPDN group.


2621(config)#vpdn-group 1

!--- Enters VPDN accept-dialin configuration mode 
!--- and enables the router to accept dial-in requests.

2621(config-vpdn)#accept-dialin

!--- Specifies which PPTP protocol is used.

2621(config-vpdn-acc-in)#protocol pptp

!--- Specifies the virtual template that is used 
!--- in order to clone the virtual access interface.

验证

本部分提供的信息可用于确认您的配置是否正常运行。

命令输出解释程序仅限注册用户)(OIT) 支持某些 show 命令。使用 OIT 可查看对 show 命令输出的分析。

  • show debug — 显示当前为进行故障排除而启用的 debug 命令

  • show user — 显示当前登录的用户及其状态

  • show ip route connected — 显示路由表的当前状态

  • show vpdn — 显示有关虚拟专用拨号网络 (VPDN) 中活动的第 2 层隧道协议 (L2TP) 或第 2 层转发 (L2F) 协议隧道和消息标识符的信息

这是 show debug 命令的输出示例。

2621#show debug
PPP:
  PPP authentication debugging is on
  PPP protocol negotiation debugging is on


VPN:
  VPDN events debugging is on

这是已配置初始 PPTP 的 debug 输出。
