简介

在某些环境中,可能需要将多个串行链路进行捆绑以作为具有聚合带宽的单个链路。本文档介绍如何配置 Cisco 4500 路由器,以使用一个虚拟模板接口对四个串行接口进行链路捆绑。

此配置可用于通过租用线路连接的路由器,或用于具有信道服务单元/数据服务单元 (CSU/DSU) 的路由器。您可以根据需要向此配置中添加其他功能。

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。

  • 实验室环境中带有原始配置的 Cisco 4500 路由器。

  • Cisco IOS�版本12.2(10b)在两路由器运行。

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。

相关产品

此配置也可用于下列硬件和软件版本。

  • 任意两台路由器,其中每台服务器带有四个串行接口。

  • 可使用 WIC-1T 和 WIC-2T 串行接口。

配置

曾在 4500 系列路由器上使用 Cisco IOS 软件版本 12.2(10b) 对此配置进行过测试。相同的配置概念同样适用于类似的路由器拓扑或其他 Cisco IOS 版本。

配置以下内容以实施上面的配置:

  • 多链路虚拟模板

  • 接口虚拟模板

  • 必须进行捆绑的每个串行接口中的 PPP 多链路。

  • RIP 作为 IP 路由协议

配置 interface loopback 0 以确保绝不会发生故障,并且 ip unnumbered loopback 0 通过同一 IP 地址来增强 5 个以上串行接口的捆绑。

当所有串行接口都运行时,将会发送用户流量,多链路 PPP 创建一个虚拟访问接口,并发生 PPP 协商。将从虚拟模板来克隆此虚拟访问接口的配置。在此虚拟访问接口中对正在运行的串行接口进行捆绑,并生成一个聚合带宽。

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

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 ppp negotiation - 用于查看客户端是否正在传递 PPP 协商;此命令用于检查地址协商。

  • debug ppp authentication -看见客户端可以是否通过认证。如果您使用的是 11.2 之前的 Cisco IOS 软件版本,请改用 debug ppp chap 命令。

  • debug ppp error - 显示和PPP连接协商与操作相关的协议错误以及统计错误。

  • debug vtemplate - 用于显示虚拟模板克隆以形成虚拟访问接口。

  • debug ppp multilink events - 用于查看 PPP 多链路事件调试。显示与影响多链路组的事件有关的信息。

  • show ppp multilink - 用于查看多链路捆绑的成员。

以下输出是从 Cisco 4500 路由器获得的。这些输出显示路由器正在建立多链路 PPP 连接。
