簡介

本文描述如何在具有BRI介面的兩台路由器之間配置按需撥號路由(DDR)。在此配置中，小型辦公室、家庭辦公室(SOHO)路由器在需要將流量傳送到中央網路時撥打中央站點路由器。如果使用者定義的時間段內沒有流量，則連線會自動關閉。此網路還使用開放最短路徑優先(OSPF)路由協定和ip ospf demand-circuit命令，以防止在DDR鏈路中斷時刪除遠端側網路的任何路由。但是，無需路由協定即可通過該鏈路運行。

必要條件

需求

以下幾點描述了配置DDR鏈路之前應確定的幾個設計因素。

  • DDR實施：您可以使用撥號器對應（傳統DDR）或撥號器設定檔。有關這兩種實現之間的差異的詳細資訊，請參閱使用撥號器配置檔案配置ISDN DDR。在此配置中，我們使用撥號器對映。

  • 單或雙向撥號：您可以將每台路由器配置為通過撥打另一端來啟動DDR鏈路，或者只能讓一端（通常是SOHO）啟動撥號連線。檢查您的流量模式，並在決定使用哪種撥號方法之前考慮以下資訊：

    • 如果兩台路由器都撥號：

      • 當有流量發往另一台路由器的網路時，任一站點都可以啟動鏈路。

      • 兩台路由器可能同時撥號，從而導致消息繁忙。

    • 如果撥號限制在SOHO路由器：

      • 如果鏈路未開啟，則從中央站點發往SOHO路由器的流量將失敗。

      • 您將避免因「衝突」呼叫而出現忙消息。

    注意：在本示例中，只有SOHO路由器啟動DDR鏈路。

  • 路由協定：您可以選擇在鏈路上運行路由協定，但必須確保定期更新（如hello）被標籤為無趣，以便鏈路不會無限期保持運行。此外，路由協定應保持路由表不變，並且鏈路關閉後不應丟棄路由。這可以通過ip ospf demand-circuit命令或快照路由來完成。如果不想使用路由協定，則可以在下一跳指向另一路由器的BRI介面的每台路由器上配置靜態路由。

  • 有趣的流量：定義DDR相關流量時一定要小心。在任一端未正確定義相關流量可能會阻止鏈路在需要時啟動、過早斷開或甚至根本未斷開。例如，您可能希望將所有路由協定流量標籤為無趣，因此定期更新不會無限期保持鏈路正常運行。

採用元件

此配置是使用以下軟體和硬體版本開發和測試的：

  • 一台運行Cisco IOS®軟體版本12.1(5)T的Cisco 1604 SOHO路由器，帶有一個BRI U介面

  • 運行Cisco IOS 12.1(2)的Cisco 3640路由器，其上有NM-4B-U（四個BRI U介面）

注意：如果路由器是OSPF點對點拓撲（2台路由器）的一部分，則只需使用ip ospf demand-circuit命令配置需求電路的一端。但是，所有路由器必須在區域內載入此功能，並且必須支援ip ospf demand-circuit命令。如果路由器是OSPF點對多點拓撲（例如中心輻射和分支）的一部分，則只能使用此命令配置多點終端。

輸出直譯器工具支援某些show命令，該工具允許您檢視show命令輸出的分析。

  • show dialer interface [type number ] — 顯示為DDR配置的介面的一般診斷資訊，並顯示計時器的配置和連線超時前的時間。您應該驗證以下消息：

    • 「Dialer state is data link layer up」 — 撥號器正常啟動。

    • 「Physical layer up」 — 線路協定啟動，但網路控制協定(NCP)未啟動。

    • 「撥號原因」該選項顯示發起撥號的資料包的源地址和目的地址。

  • show isdn status — 確保路由器與ISDN交換機正確通訊。此命令還顯示活動呼叫數您應驗證以下消息：

    • "第1層狀態為ACTIVE",

    • "第2層狀態狀態= MULTIPLE_FRAME_ESTABLISHED"

    注意：有關詳細資訊，請參閱使用show isdn status命令進行BRI故障排除。

  • show caller user username detail — 顯示詳細的LCP協商引數。

注意：來自遠端端的OSPF路由（尤其是預設路由）將新增到路由表中。這允許客戶端(maui-soho-01)在需要通過BRI鏈路傳送流量時撥打BRI鏈路。由於這是OSPF需求電路，因此當鏈路因撥號器空閒超時過期而關閉時，不會刪除（老化）路由表中的OSPF條目。

在show caller user username detail輸出中，注意連線的空閒超時。

debug指令

注意：發出debug指令之前，請先參閱有關Debug指令的重要資訊。

  • debug isdn q931 — 顯示ISDN網路連線（第3層）的呼叫建立和斷開。

  • debug isdn q921 — 顯示路由器和ISDN交換機之間D通道上的資料鏈路層消息（第2層）。如果show isdn status命令不顯示第1層和第2層為up，請使用此調試。

  • debug dialer [events | packets] -顯示有關撥號器介面上接收的資料包的DDR調試資訊。

  • debug ppp negotiation — 在協商PPP元件(包括鏈路控制協定(LCP)、身份驗證和NCP時，顯示有關PPP流量和交換的資訊。成功的PPP協商將首先開啟LCP狀態，然後進行身份驗證，最後協商NCP（通常是IPCP）。

  • debug ppp authentication — 顯示PPP身份驗證協定消息，包括質詢身份驗證協定(CHAP)資料包交換和口令身份驗證協定(PAP)交換。

  • 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。
