簡介

在某些環境中，可能需要捆綁多個串列鏈路來充當具有聚合頻寬的單個鏈路。本文檔介紹如何使用虛擬模板介面配置Cisco 4500路由器捆綁四個串列介面。

此配置可用於通過租用線路連線的路由器或具有通道服務單元/資料服務單元(CSU/DSU)的路由器。 您可以根據需要為此配置新增其他功能。

必要條件

需求

本文件沒有特定需求。

採用元件

本檔案中的資訊是根據以下軟體和硬體版本。

  • 實驗環境下的思科4500路由器，已清除配置。

  • 兩台路由器上都運行了Cisco IOS®版本12.2(10b)。

本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您在即時網路中工作，請確保在使用任何命令之前瞭解其潛在影響。

相關產品

此配置還可以用於以下硬體和軟體版本。

  • 任意兩台每台都有四個串列介面的路由器。

  • 可以使用WIC-1T和WIC-2T串列介面。

組態

此配置已在4500系列路由器上使用Cisco IOS軟體版本12.2(10b)進行測試。相同的配置概念適用於類似的路由器拓撲或其他Cisco IOS版本。

配置以下內容以實施上述配置：

  • multilink virtual-template

  • interface virtual-template

  • 捆綁必須完成的每個串列介面中的PPP多鏈路。

  • 作為IP路由協定的RIP

介面loopback 0配置為永不發生故障，而ip unnumbered loopback 0增強了具有相同IP地址的五個以上串列介面的捆綁。

當所有串列介面都處於開啟狀態並且要傳送使用者流量時，多鏈路PPP會建立一個虛擬訪問介面，並發生PPP協商。此虛擬訪問介面的配置從虛擬模板克隆。已啟動的串列介面數量捆綁在此虛擬訪問介面中，並建立一個聚合頻寬。

輸出直譯器工具(僅供註冊客戶使用)支援某些show命令，此工具可讓您檢視show命令輸出的分析。

注意：發出debug指令之前，請先參閱有關Debug指令的重要資訊。

  • debug ppp negotiation — 檢視客戶端是否正在傳遞PPP協商；此命令用於檢查地址協商。

  • debug ppp authentication — 檢視客戶端是否正在傳遞身份驗證。如果您使用的是11.2之前的Cisco IOS軟體版本，請改用debug ppp chap命令。

  • debug ppp error — 顯示與PPP連線協商和操作相關的協定錯誤和錯誤統計資訊。

  • debug vtemplate — 顯示虛擬模板克隆以形成虛擬訪問介面。

  • debug ppp multilink events — 檢視PPP多鏈路事件調試。顯示有關影響多連結組的事件的資訊。

  • show ppp multilink — 檢視多鏈路捆綁的成員。

從Cisco 4500路由器獲得以下輸出。它們顯示建立多鏈路PPP連線的路由器。
