使用撥號程式設定檔的非同步備份

簡介

本文檔介紹如何配置遠端路由器(Cisco 3640)，使其在幀中繼連線斷開時使用模擬POTS線路撥打中心站點。Cisco 3640使用撥號程式設定檔為訊框中繼連結提供備份介面。此外，還預留了一個特定的非同步介面用於備份撥出。請注意，此配置可以擴展為包括多鏈路PPP，這將顯著增加備份連線的可用頻寬。如需詳細資訊，請參閱適用於DDR的多連結PPP — 基本組態和驗證檔案。

本文顯示如何在非同步鏈路上使用路由協定配置備份連線。在實施此類設計之前，需要仔細考慮，因為路由協定使用的頻寬可能會減少資料傳輸的可用頻寬。快照路由或靜態路由可在非同步鏈路上使用，而不是路由協定。

採用元件

本檔案中的資訊是根據以下軟體和硬體版本。

• Cisco IOS軟體版本12.0(7)T

• Cisco 3640

• 思科AS5200網路存取伺服器

• Cisco 7206

背景理論

為WAN連線（例如帶有按需撥號電路的幀中繼）提供冗餘路徑是常見的。非同步數據機和電路交換普通舊式電話服務(POTS)線路經常用於備份WAN介面。設計撥號備份方案時需要仔細規劃。必須考慮備份鏈路上的流量、容易發生故障的鏈路數量以及支援備份電路的埠容量規劃等因素。

為WAN鏈路提供備份的三種常用方法是：

• 備份介面

• 撥號器監視

• 浮動靜態路由

在主鏈路斷開之前，備用介面一直處於非活動狀態。然後啟用備用鏈路，重新建立兩個站點之間的連線。為幀中繼鏈路實施備份介面時，幀中繼鏈路上的點對點子介面是有利的，因為主介面或多點介面可能保持開啟/開啟狀態，即使主虛擬電路(PVC)關閉，也會導致備份介面未啟用。此外，建議在Cisco IOS®軟體版本12.05(T)或更高版本的網路上配置幀中繼端到端keepalive。有關詳細資訊，請參閱幀中繼端到端保活文檔。

撥號器監視提供可靠的連線，而不只是依靠定義感興趣的流量在中央路由器上觸發傳出呼叫。Dialer Watch會監控某些特定路由，如果無法到達這些網路，Dialer Watch會啟動輔助鏈路。有關撥號器監視的詳細資訊，請參閱使用BRI和撥號器監視配置DDR備份文檔。

浮動靜態路由的管理距離大於動態路由的管理距離。可以在靜態路由上配置管理距離，以便靜態路由比動態路由更不可取；因此，當動態路由可用時，不使用靜態路由。但是，如果動態路由丟失，則靜態路由可以接管，流量可以通過此備用路由傳送。有關如何使用浮動靜態路由配置備份的示例，請參閱為幀中繼配置ISDN備份文檔。

設計撥號備份方案時，切記要考慮各種因素，例如備份鏈路上的流量模式、可能失敗的鏈路數以及在最壞情況下中心站點上可用的埠數。

設定

本節提供用於設定本文件中所述功能的資訊。

網路圖表

本文檔使用下圖所示的網路設定。

組態

本文檔使用如下所示的配置。

注意：本文檔中的配置基於在Cisco 3640和AS5200網路接入伺服器上運行的Cisco IOS軟體版本12.0(7)T。Cisco 3640有一個NM-8AM模擬數據機網路模組卡，該卡允許路由器在不使用外部數據機的情況下發出最多八個傳出模擬呼叫。

AS5200已配置為常規接入伺服器，能夠支援ISDN和非同步撥號使用者以及備份連線。

maui-rtr-06(Cisco 7206)的配置與撥號備份方案無關。Cisco 7206僅用於終止傳入WAN鏈路。無需配置來演示非同步備份。
