目录


简介

此配置展示使用综合业务数字网络(ISDN)基本速率接口(BRI)线路备份一租用的线路连接。到主要接口断开之时, backup interface命令放置指定的接口到备用模式。关于备份接口的功能的更多信息,参考评估备份接口、浮动静态路由和Dialer Watch DDR备份的

先决条件

要求

推荐您参考配置和故障排除DDR备份文件欲知更多信息。

使用的组件

在此方案中我们有一Cisco 1604路由器连接对在串行连接间的一个Cisco 3640路由器。两路由器也配备有BRI接口,使用备份链路。Cisco 1604运行思科IOS�软件Release12.1(5)T,并且Cisco 3640使用Cisco IOS 12.1(2)。

注意: 概念在此配置方面在所有路由器可以使用与BRI和广域网接口。

本文档中的信息都是基于特定实验室环境中的设备创建的。本文档中使用的所有设备最初均采用原始(默认)配置。如果您是在真实网络上操作,请确保您在使用任何命令前已经了解其潜在影响。

背景理论

此示例使用传统按需拨号路由(DDR),使用dialer map命令BRI连接。您能也使用拨号配置文件而不是传统DDR。关于参考的拨号配置文件的更多信息配置与拨号配置文件的ISDN DDR

配置DDR备份介入二不同步骤:

  1. 配置DDR以传统DDR或拨号配置文件。在实施备份配置前验证您的DDR连接正常工作。

  2. 当主链路发生故障时,请配置路由器首次DDR连接。此配置使用备份接口触发拨出。参考的评估备份接口、浮动静态路由和Dialer Watch DDR备份的欲知更多信息关于其它选项。

配置

本文档使用如下所示的配置。

此配置使用一个BRI电路备份串行链路。此配置也使用在两路由器之间的开放最短路径优先(OSPF)路由协议。一旦备用连接激活,您必须保证路由表更新使用新的备份路由。

验证下列问题在客户端里毛伊SOHO的配置01(1600) :

  • 使用环回地址。使用这,因此OSPF的路由器ID不会更改,并且备份链路能设立对等体,当激活时。

  • 拨号负载门限值是集合低。如果不需要128k多链路备用连接,此值可以更改。

  • 任何 IP 流量都将触发拨号(基于 dialer-list 1 和 dialer-group 1)。因为备份链路要求触发数据流拨通备份链路,以验证您有生成触发数据流的数据流源。在本示例中,OSPF hello 数据包将触发拨号。如果您没有使用路由协议,您可以使用ICMP Ping来拨打备份链路。根据需要来调节相关流量。

  • 使用OSPF。您能使用您希望的所有路由协议。请确保主要接口和备用接口主网络在路由协议包括。如果希望使用静态路由而不是路由协议,请创建有是的下一跳的静态路由远程BRI接口(您可以必须根据方案做它浮动静态路由)。

在服务器 maui-nas-05 (3640) 的配置中,验证以下几点:

  • 远程站点的一个拨号映射语句配置。一个不正确拨号映射语句能导致在已连接备份链路的路由问题。

  • 所有IP数据流定义作为有趣的。这将重置空闲超时并且保持连接,直到主要的恢复。如果不需要将被固定的备份链路,您能更改此。

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。

输出解释器工具支持某些 show 命令(只限于注册用户),通过它可以查看 show 命令输出的分析。

  • show interface bri0 -这指示BRI接口是否是UP。如果主链路是UP, BRI接口在待机。只有当主链路断开BRI接口将是UP。

  • show isdn status -请使用此保证路由器用ISDN交换机适当地通信。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。

show ip route 输出示例

客户端的路由表, maui-soho-01 (1600),与主链路作用如下所示:

maui-soho-01#show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area 
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
       i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
       * - candidate default, U - per-user static route, o - ODR
       P - periodic downloaded static route

O       172.22.1.1 [110/65] via 192.168.10.1, 00:00:23, Serial0

显示的show ip route输出如上,显示从使用主链路(serial0)的对等体的OSPF获知的路由。现在我们减少主链路并且激活备份链路。

注意: 发出在主要接口的shutdown命令不会造成备份BRI拨号。如果发出shutdown命令减少主要连接, Cisco IOS软件不会自动地启动备用连接。您必须通过拔掉电缆或某个等效方法为了启动备份接口物理的减少主要连接。

在备份链路被激活了后, OSPF表交换,并且新的路由使用备份链路安装。此时,流量将流过备份链路。此命令示例如下:

maui-soho-01#show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

       i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
       * - candidate default, U - per-user static route, o - ODR
       P - periodic downloaded static route

故障排除

本部分提供的信息可用于对配置进行故障排除。

故障排除命令

输出解释器工具支持某些 show 命令(只限于注册用户),通过它可以查看 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 dialer -这用于发现按需拨号路由信息。

  • debug isdn events - 用于查看发生在ISDN接口用户端上的ISDN活动。

  • debug isdn q931 -这表示呼叫建立并且切断ISDN网络连接(层3)和可以用于隔离问题。

  • debug ppp协商-这显示关于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)、验证和网络控制协议时(NCP)。成功的PPP协商将打开LCP状态,然后首先验证和终于协商NCP。

  • debug ppp authentication -这显示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。如果您发现故障,则请验证是否正确配置了 CHAP 用户名和口令。

  • debug ppp error -这显示协议错误和错误统计信息关联与PPP连接协商和操作。
