简介

本文档提供两个Cisco路由器之间PPP回叫的示例配置。

先决条件

要求

本文档没有任何特定的要求。

使用的组件

本文档中的信息基于以下软件和硬件版本：

  • Cisco IOS®软件版本12.0(3)T或更高版本。

注意：要借助AAA服务器分配的回叫字符串配置PPP回叫，您需要使用dialer aaa 命令，该命令在Cisco IOS软件版本12.0(3)T或更高版本中可用。但是，在Cisco IOS版本12.1(4)T、12.2(1)T及更高版本中，使用AAA服务器分配的回叫字符串进行PPP回叫时不需要此命令。

注意：仅传统DDR支持dialer aaa命令(如图1所示)。

本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您使用的是真实网络，请确保您已经了解所有命令的潜在影响。

规则

有关文档规则的详细信息，请参阅 Cisco 技术提示规则。

背景信息

TACACS+（AAA服务器）用于向回叫服务器提供回叫拨号字符串。但是，您也可以使用RADIUS提供回叫字符串。要使用本地身份验证、授权和记帐(AAA)配置PPP回叫，请参阅配置PPP ISDN回叫。

在此示例配置中，回叫使用PPP和RFC 1570中指定的设施。ISDN电路上的PPP回叫按以下顺序完成：

  1. 回叫客户端启动并启动到回叫服务器路由器的ISDN连接。

  2. 回叫客户端和回叫服务器协商PPP链路控制协议(LCP)。 在LCP协商中，回叫请求、协商和同意。

  3. 回叫客户端和回叫服务器使用PPP密码身份验证协议(PAP)或质询握手身份验证协议(CHAP)相互进行身份验证。 但是，您可以通过ppp authentication chap callin命令配置回叫客户端，使其不对回叫服务器进行身份验证。

  4. 回叫服务器从AAA服务器获取必要的回叫属性，例如回叫拨号字符串（客户端的电话号码）。

  5. 两台路由器都会断开ISDN连接。

  6. 回叫服务器向客户端发起回叫。当呼叫连接时，路由器会相互验证，并建立链路。

配置

本部分提供有关如何配置本文档所述功能的信息。

本文档使用以下网络设置：

配置

本文档使用以下配置：

  • 免费软件TACACS+配置

  • RADIUS 配置

  • 备用RADIUS配置

  • Tnt-buster（回叫服务器）配置

  • Tremans（回叫客户端）配置

免费软件TACACS+配置 
user = tremens {
  default service = permit
  login = cleartext "cisco"
  chap = cleartext "cisco"
  
!--- CHAP password.

  service = ppp protocol = lcp {
  callback-dialstring = "6083"

 !--- Number to callback.

  send-secret = "cisco"
  }
  }

您还可以使用RADIUS作为AAA服务器来提供回调属性，而不是TACACS+。RADIUS配置示例如下：

RADIUS 配置 
tremens         Auth-Type = Local, Password = "cisco"
                Service-Type = Framed-User,

 !--- Service-Type(6) is Framed User(4).

                Cisco-AVPair = "lcp:callback-dialstring=6083", 
                Cisco-AVPair = "lcp:send-secret=cisco"

注意：在上面显示的RADIUS配置中，在对回叫进行身份验证时需要Cisco AVPair lcp:send-secret=cisco。如果不包含此AVPair，则必须在回叫服务器上本地配置远程路由器的CHAP用户名和密码。

注意：本文档主要处理TACACS+。本文档中提供的调试不显示RADIUS启动的回调。

注意：从Cisco IOS版本12.1(7)，可以使用互联网工程任务组(IETF)RADIUS属性19进行ISDN和模拟Microsoft回叫。在这种情况下，无需使用Cisco AVPair，如前面的配置所示。请参阅此处显示的备用RADIUS配置示例：

备用RADIUS配置 
tremens         Auth-Type = Local, Password = "cisco"
                Service-Type = callback framed
                
!--- Service-Type (6) is callback framed (4).

                
!--- Callback framed is also known as !--- Dialback-Framed-User.

                Callback =6083
                
!--- IETF RADIUS Callback attribute (19) with the phone !--- number for the callback.

注意：RADIUS调试将显示返回回调服务器的IETF RADIUS属性19。

验证

本部分所提供的信息可用于确认您的配置是否正常工作。

命令输出解释程序工具（仅限注册用户）支持某些 show 命令，使用此工具可以查看对 show 命令输出的分析。

  • show dialer interface type number — 显示为按需拨号路由(DDR)配置的接口的常规诊断信息。 启动拨号的数据包的源地址和目标地址显示在 dial reason line 中。此命令还显示连接计时器。

  • show isdn status — 使您能够确保路由器与ISDN交换机正确通信。在输出中，验证第1层状态是否为活跃状态，是否第2层状态=MULTIPLE_FRAME_ESTABLISHED出现。此指令也显示活动的呼叫的数量。

故障排除

本部分提供的信息可用于对配置进行故障排除。

有关debug命令的详细信息，请参阅《Cisco IOS 12.0版调试命令参考》。

故障排除命令（可选）

命令输出解释程序工具（仅限注册用户）支持某些 show 命令，使用此工具可以查看对 show 命令输出的分析。

注意：在发出debug命令之前，请参阅有关Debug命令的重要信息。

  • debug isdn q931 — 显示ISDN网络连接（第3层）的呼叫建立和断开。

  • debug dialer [events | packets ] — 显示有关拨号程序接口上收到的数据包的DDR调试信息。

  • debug aaa authentication - 显示有关 AAA 身份验证的信息。

  • debug aaa authorization - 显示有关 AAA 授权的信息。

  • debug tacacs — 显示与TACACS+关联的详细调试信息。

  • debug ppp negotiation — 显示PPP组件协商过程中有关PPP流量和交换的信息，包括链路控制协议(LCP)、身份验证和NCP。成功的PPP协商将首先开放LCP状态，然后进行验证，最后进行NCP协商。

  • debug ppp authentication — 显示PPP身份验证协议消息，包括质询身份验证协议(CHAP)数据包交换和密码身份验证协议(PAP)交换。如果观察到故障，请验证CHAP用户名和密码是否配置正确。

  • debug callback — 当路由器使用调制解调器和聊天脚本在终端线路上回叫时，显示回叫事件。由于此命令用于调制解调器和聊天脚本，因此此配置中不使用此命令。
