简介

此示例配置显示如何使用ISDN BRI电路备份租用线路、WAN或串行连接。

本文档使用拨号程序配置文件和备份接口功能。backup interface命令将已配置的物理或逻辑接口置于备用模式，直到主接口关闭。

先决条件

要求

本文档没有任何特定的要求。

使用的组件

此配置使用一个BRI电路备份串行链路。路由器RAMS正在执行拨出，因为该路由器上配置了拨号程序字符串。在此配置中：

  • 使用Cisco 2500路由器(RAMSES)，与Cisco 2520路由器(sphinx)连接。 两个路由器也通过BRI接口安装，此接口用于备份链路。

  • 两台路由器都运行Cisco IOS软件版本12.0.7T。

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。

配置

本部分提供有关如何配置本文档所述功能的信息。以下三个步骤完成此配置：

  1. 使用传统DDR或拨号程序配置文件配置按需拨号路由(DDR)。本文档中显示的示例配置使用拨号程序配置文件。

  2. 当主链路发生故障时，使用backup interface命令触发拨出呼叫。

  3. 定义相关流量。

注意：建议在配置备份接口和备份延迟命令之前，配置DDR连接（使用BRI0的拨号程序1）并验证其是否正常工作。这样，在配置备份之前，您就可以有效地管理拨号程序配置文件、ISDN、PPP和身份验证问题并排除故障。

注：要查找有关本文档中使用的命令的其他信息，请使用命令查找工具(仅注册客户)。

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 isdn status??？显示所有ISDN接口或特定ISDN接口的状态。

  • show interface serial??？显示有关串行接口的信息。

  • show interface dialer???？显示有关拨号器接口的信息。

  • debug dialer??？显示有关拨号器接口上收到的数据包的DDR信息。

  • debug isdn q931???？显示路由器和ISDN交换机之间ISDN网络连接（第3层）的呼叫建立和断开。

  • debug ppp negotiation???？显示在协商PPP组件(包括链路控制协议(LCP)、身份验证和NCP)时PPP流量和交换的信息。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。如果发现故障，请验证CHAP用户名和密码是否配置正确。

故障排除

本部分提供的信息可用于对配置进行故障排除。

故障排除步骤

按照以下说明对配置进行故障排除：

使用show isdn status命令确保路由器与ISDN交换机正常通信。在输出中，验证：

  • 第1层状态为ACTIVE

  • 第2层状态状态= MULTIPLE_FRAME_ESTABLISHED

此指令也显示活动的呼叫的数量。请看下面的示例：

   ramses#show isdn status
   Global ISDN Switchtype = basic-net3
   ISDN BRI0 interface
   dsl 0, interface ISDN Switchtype = basic-net3
   Layer 1 Status:
   ACTIVE
   Layer 2 Status:
   TEI = 97, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
   Layer 3 Status:
   0 Active Layer 3 Call(s)
   Activated dsl 0 CCBs = 0
   The Free Channel Mask: 0x80000003
   Total Allocated ISDN CCBs = 0

   ramses#show interface serial 0
   Serial0 is up, line protocol is up
   Hardware is HD64570
   Internet address is 3.3.3.1/24
   Backup interface Dialer1, failure delay 10 sec, secondary disable
   delay 30 sec

   ramses#show interface dialer 1
   Dialer1 is standby mode, line protocol is down 
 ! --- In standby mode.
   Hardware is Unknown

由于备份接口处于备用模式，因此在show ip route命令的输出中看不到此信息。

让我们看一下使用管理距离(AD)和不使用管理距离(AD)时输出中显示的差异。

不使用管理距离时

不使用AD时，您会看到以下输出：

   sphinx#show interface dialer 1
   Dialer1 is up (spoofing), line protocol is up (spoofing)
   Hardware is Unknown

如果不对路由器sphinx上的拨号器使用AD，您会看到show ip route命令的以下输出：

   sphinx(config)#ip route 1.1.1.1 255.255.255.255 dialer1
   
 ! --- No AD used here.


   sphinx#show ip route 1.1.1.1
   Routing entry for 1.1.1.1/32
   Known via "static", distance 1, metric 0 (connected)
   Routing Descriptor Blocks:
   * directly connected, via Dialer1
   Route metric is 0, traffic share count is 1
   directly connected, via Serial0
   Route metric is 0, traffic share count is 1

ping命令显示的输出类似于以下内容，因为它缺少其中一个ping:

   sphinx#ping 1.1.1.1
   Type escape sequence to abort.
   Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds:
   .!.!.

使用管理距离时

使用AD时，您会看到以下输出：

   sphinx(config)#ip route 1.1.1.1 255.255.255.255 dialer1 2
 
 ! --- The AD used here is two.


   sphinx#show ip route 1.1.1.1
   Routing entry for 1.1.1.1/32
   Known via "static", distance 1, metric 0 (connected)
   Routing Descriptor Blocks:
   * directly connected, via Serial0
   Route metric is 0, traffic share count is 1

   sphinx#ping 1.1.1.1
   Type escape sequence to abort.
   Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds:
   !!!!!

在配置备份接口和备份延迟命令之前，请配置并验证DDR连接（在拨号器1和BRI0之间）是否正常工作。这样，在配置备份之前，您可以验证拨号程序配置文件、ISDN、PPP和身份验证是否正常运行。

验证DDR连接是否正常工作后，您可以继续执行下面列出的以下备份故障排除步骤：

  1. 关闭主链路。

    注意：请勿在路由器上使用shutdown命令，并配置备份接口命令。这不会导致Cisco IOS拨打备份链路。通过关闭不带有backup interface命令的路由器上的主要接口，您可以激活备份。

    注意：在我们的场景中，备份接口命令在rams（Cisco 2500路由器）上配置。 因此，对sphinx的主接口（Cisco 2520路由器）执行shutdown命令会激活备用链路。

    注意：您可以通过拔掉电缆或使用某种等效方法来物理断开主连接，以打开备份接口。

  2. 您应该看到一条控制台消息，指明备份接口（接口拨号程序 1）已接通。此消息仅在备份延迟命令指定的间隔时间过期后显示。在此配置中，备份激活延迟为 10 秒。

    如果未看到此控制台消息，请检查 backup delay 计时器。

       *Mar 1 03:54:00.451: %LINEPROTO-5-UPDOWN: Line protocol on Interface
   Serial0, changed state to down
   *Mar 1 03:54:11.467: %LINK-3-UPDOWN: Interface Dialer1, changed state to up

  3. 使用 show ip route 命令来查看主链路关闭时的路由表。您应该观察到到Dialer 1的直连路由。

  4. 对远程路由器的环回接口的IP地址执行ping操作。如果链路不拨号，请验证相关流量定义是否允许ICMP流量(ping)。

    注意：在我们的示例中，路由器sphinx中的路由使用AD(2)（这可以是除1以外的任意数字）。

    ip route 1.1.1.1 255.255.255.255 Dialer1 2

    注意：造成这种情况的原因是，如果主链路已打开，一半的ping会丢失。由于拨号器1和串行0接口都处于打开状态，因此路由已安装到两个接口。但是，由于BRI接口未打开，拨号器接口无法发送数据包。

故障排除命令

使用本节中所示的命令排除配置故障。

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。
