简介

此配置示例显示您如何能使用ISDN BRI电路备份一条租用的线路、广域网或者串行连接。

本文使用拨号配置文件和备用接口功能。backup interface命令在备用模式放置已配置的物理或逻辑接口,直到这样次象主要接口断开。

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。因为dialer string在该路由器,配置路由器ramses执行拨出。在此配置中:

  • 使用Cisco 2500路由器(ramses),连接对思科2520路由器(狮身人面象)。两个路由器也通过BRI接口安装,此接口用于备份链路。

  • 两路由器运行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。这三个步骤完成此配置:

  1. 配置与传统DDR或拨号配置文件的按需拨号路由(DDR)。在本文显示的配置示例使用拨号配置文件。

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

  3. 定义关注数据流。

注意: 推荐您配置是工作正常的DDR连接(与BRI0的拨号1)并且验证,在您配置备份接口backup delay命令前。在您配置备份前,这允许您有效管理和排除故障拨号配置文件, ISDN、PPP和验证问题。

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接口或一个特定ISDN接口状况。

  • show interface serial ? ? ?显示关于serial interfaces的信息。

  • show interface dialer ? ? ?显示关于拨号接口的信息。

  • debug dialer ? ? ?显示关于在拨号接口接收的数据包的DDR信息。

  • 调试isdn q931???Shows呼叫建立并且切断ISDN网络连接(在路由器和ISDN交换机之间的层3)。

  • debug ppp协商? ? ?显示关于PPP流量的信息并且交换,当协商PPP组件包括链路控制协议(LCP)、验证和NCP时。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认证协议消息,包括质询验证协议(CHAP)信息包交换和密码认证协议交换。如果观察一失败,请验证CHAP用户名和密码正确地配置。

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

遵从这些说明排除故障您的配置:

请使用show isdn status命令保证路由器用ISDN交换机适当地通信。在输出中,请验证那:

  • 第1层状态是活跃的

  • 第2层状态=MULTIPLE_FRAME_ESTABLISHED出现。

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

因为备份接口在备用模式,您在输出看不到此信息show ip route命令中

请查看在输出中显示出的差异,当曾经管理距离时(AD)使用一个,和,当不。

使用管理距离,当不

使用AD,当不,您看到以下输出:

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

如果不使用AD在路由器狮身人面象的拨号程序,您看到从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命令看起来显示的输出类似于以下,因为未命中其中一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:
   .!.!.

当曾经管理距离时

当曾经AD时,您看到以下输出:

   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:
   !!!!! 

配置并且验证DDR连接(在拨号1和BRI0之间)是工作正常,在您配置备份接口backup delay命令前。这允许您验证拨号配置文件、ISDN、PPP和验证在配置备份前正确地作用。

一旦验证DDR连接是工作正常,您能继续到如下被概述的以下备份故障排除步骤:

  1. 关闭主链路。

    注意: 请勿对配置了 backup interface 命令的路由器使用 shutdown 命令。这不造成Cisco IOS拨号备份链路。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: 在我们的方案中, backup interface命令在ramses (Cisco 2500路由器)配置。所以,执行在主要接口的一shutdown命令狮身人面象(思科2520路由器)激活备份链路。

    注意: 您能通过拔掉电缆或者使用某个等效方法,为了启动备份接口物理的减少主要连接。

  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。此消息在间隔时间之后只出现,指定由backup delay命令,超时。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。您应该直接地观察一已连接路由到拨号1。

  4. ping远程路由器的回环接口的IP地址。如果链路不拨号,请验证您的触发数据流定义允许ICMP流量(ping)。

    注意: 在我们的示例中, AD两使用路由在路由器狮身人面象(这可以是任何编号除一个之外)。

    ip route 1.1.1.1 255.255.255.255 Dialer1 2

    注意: 对此的原因是,如果主链路是UP, ping的半丢失。因为拨号1和serial0接口是UP,路由为两个接口安装。然而,因为BRI接口不上升,拨号接口不能发送数据包。
