簡介

此配置示例說明如何使用ISDN BRI電路備份租用線路、WAN或串列連線。

本檔案使用撥號程式設定檔和備份介面功能。backup interface命令將配置的物理或邏輯介面置於備用模式，直到主介面關閉為止。

必要條件

需求

本文件沒有特定需求。

採用元件

此配置使用BRI電路備份串列鏈路。由於該路由器上配置了撥號器字串，因此路由器衝壓正在執行撥出。在此組態中：

  • 使用Cisco 2500路由器(RAMSES)，連線到Cisco 2520路由器(sphinx)。 兩台路由器都配備了用於備份鏈路的BRI介面。

  • 兩台路由器都運行Cisco IOS軟體版本12.0.7T。

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。如果您的網路正在作用，請確保您已瞭解任何指令可能造成的影響。

慣例

如需文件慣例的詳細資訊，請參閱思科技術提示慣例。

設定

本節提供用於設定本文件中所述功能的資訊。以下三個步驟完成了此配置：

  1. 使用傳統DDR或撥號程式配置檔案配置按需撥號路由(DDR)。本文檔中顯示的配置示例使用撥號程式配置檔案。

  2. 在主鏈路發生故障時，使用backup interface命令觸發撥出呼叫。

  3. 定義相關流量。

注意：建議在配置備份介面和備份延遲命令之前，配置DDR連線（使用BRI0的撥號程式1）並驗證其是否正常工作。這允許您在配置備份之前有效地管理和排除撥號程式配置檔案、ISDN、PPP和身份驗證問題。

注意：要查詢有關本文檔中使用的命令的其他資訊，請使用命令查詢工具(僅限註冊客戶)。

驗證

本節提供的資訊可用於確認您的組態是否正常運作。

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。

  • show isdn status???顯示所有ISDN介面或特定ISDN介面的狀態。

  • show interface serial -???示有關串列介面的資訊。

  • show interface dialer -???示有關撥號器介面的資訊。

  • debug dialer -???示有關撥號器介面上接收的資料包的DDR資訊。

  • debug isdn q931???顯示路由器和ISDN交換機之間的ISDN網路連線（第3層）的呼叫建立和斷開。

  • 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。

  • 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。如果發現故障，請驗證CHAP使用者名稱和密碼是否配置正確。

疑難排解

本節提供的資訊可用於對組態進行疑難排解。

疑難排解步驟

請按照以下說明對配置進行故障排除：

使用show isdn status命令確保路由器與ISDN交換機正確通訊。在輸出中，確認：

  • 第1層狀態為ACTIVE

  • 第2層狀態狀態= MULTIPLE_FRAME_ESTABLISHED

此命令還顯示活動呼叫的數量。我們來看一個例子：

   ramses#show isdn status
   Global ISDN Switchtype = basic-net3
   ISDN BRI0 interface
   dsl 0, interface ISDN Switchtype = basic-net3
   Layer 1 Status:
   ACTIVE
   Layer 2 Status:
   TEI = 97, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
   Layer 3 Status:
   0 Active Layer 3 Call(s)
   Activated dsl 0 CCBs = 0
   The Free Channel Mask: 0x80000003
   Total Allocated ISDN CCBs = 0

   ramses#show interface serial 0
   Serial0 is up, line protocol is up
   Hardware is HD64570
   Internet address is 3.3.3.1/24
   Backup interface Dialer1, failure delay 10 sec, secondary disable
   delay 30 sec

   ramses#show interface dialer 1
   Dialer1 is standby mode, line protocol is down 
 ! --- In standby mode.
   Hardware is Unknown

由於備份介面處於備用模式，因此在show ip route命令的輸出中看不到此資訊。

使用管理距離(AD)和不使用管理距離時，讓我們看一下輸出中顯示的差異。

不使用管理距離時

如果不使用AD，您將看到以下輸出：

   sphinx#show interface dialer 1
   Dialer1 is up (spoofing), line protocol is up (spoofing)
   Hardware is Unknown

如果沒有在路由器sphinx上使用AD作為撥號程式，則會看到show ip route命令的以下輸出：

   sphinx(config)#ip route 1.1.1.1 255.255.255.255 dialer1
   
 ! --- No AD used here.


   sphinx#show ip route 1.1.1.1
   Routing entry for 1.1.1.1/32
   Known via "static", distance 1, metric 0 (connected)
   Routing Descriptor Blocks:
   * directly connected, via Dialer1
   Route metric is 0, traffic share count is 1
   directly connected, via Serial0
   Route metric is 0, traffic share count is 1

ping命令顯示的輸出看起來與以下類似，因為它缺少其中一個ping:

   sphinx#ping 1.1.1.1
   Type escape sequence to abort.
   Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds:
   .!.!.

使用管理距離時

使用AD時，您將看到以下輸出：

   sphinx(config)#ip route 1.1.1.1 255.255.255.255 dialer1 2
 
 ! --- The AD used here is two.


   sphinx#show ip route 1.1.1.1
   Routing entry for 1.1.1.1/32
   Known via "static", distance 1, metric 0 (connected)
   Routing Descriptor Blocks:
   * directly connected, via Serial0
   Route metric is 0, traffic share count is 1

   sphinx#ping 1.1.1.1
   Type escape sequence to abort.
   Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds:
   !!!!!

配置並驗證DDR連線（撥號器1和BRI0之間）是否工作正常，然後再配置備份接口和備份延遲命令。這樣，您就可以在配置備份之前驗證撥號器配置檔案、ISDN、PPP和身份驗證是否正常工作。

驗證DDR連線正常工作後，可以繼續執行以下備份故障排除步驟：

  1. 關閉主鏈路。

    注意：請勿在配置了backup interface命令的路由器上使用shutdown命令。這不會導致Cisco IOS撥打備份鏈路。您可以在沒有backup interface命令的路由器上關閉主介面，以啟用備份。

    註：在我們的方案中，backup interface命令是在ramses（Cisco 2500路由器）上配置的。 因此，對sphinx（思科2520路由器）的主介面執行shutdown命令會啟用備用鏈路。

    注意：您可以通過拔下電纜或使用某種等效的方法來物理關閉主連線，以便啟動備用介面。

  2. 您應該會看到一條控制檯消息，指示備用介面(interface dialer 1)已啟動。此消息僅在由backup delay命令指定的時間間隔過期後顯示。在此配置中，備份啟用延遲為10秒。

    如果未看到此控制檯消息，請檢查備份延遲計時器。

       *Mar 1 03:54:00.451: %LINEPROTO-5-UPDOWN: Line protocol on Interface
   Serial0, changed state to down
   *Mar 1 03:54:11.467: %LINK-3-UPDOWN: Interface Dialer1, changed state to up

  3. 使用show ip route命令檢視主鏈路關閉的路由表。您應該觀察到Dialer 1的直連路由。

  4. Ping遠端路由器環回介面的IP地址。如果連結沒有撥號，請確認您的相關流量定義允許ICMP流量(ping)。

    注意：在我們的示例中，路由器斯芬克斯中的路由使用2的AD（這可以是除1之外的任何數字）。

    ip route 1.1.1.1 255.255.255.255 Dialer1 2

    注意：出現這種情況的原因是，如果主鏈路處於開啟狀態，則ping操作會有一半丟失。由於dialer 1和serial 0介面均已啟用，因此該路由已同時安裝用於這兩個介面。但是，由於BRI介面未啟動，撥號器介面無法傳送資料包。

疑難排解指令
