簡介

此組態示範了使用整合服務數位網路(ISDN)基本速率介面(BRI)線路備份租用線路連線。backup interface命令將指定的介面置於standby模式，直到主介面關閉為止。有關備份介面功能的詳細資訊，請參閱評估備份介面、浮動靜態路由和DDR備份的撥號器監視。

必要條件

需求

有關詳細資訊，建議您參閱配置和故障排除DDR備份文檔。

採用元件

在此場景中，Cisco 1604路由器通過串列連線連線到Cisco 3640路由器。兩台路由器還都配備了BRI介面，用於備份鏈路。Cisco 1604運行Cisco IOS®軟體版本12.1(5)T，Cisco 3640使用Cisco IOS 12.1(2)。

注意：此配置中的概念可用於具有BRI和WAN介面的任何路由器。

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。

背景理論

本示例使用傳統按需撥號路由(DDR)，它對BRI連線使用dialer map命令。您還可以使用撥號程式設定檔，而不是舊式DDR。有關撥號程式配置檔案的詳細資訊，請參閱使用撥號程式配置檔案配置ISDN DDR。

配置DDR備份包括兩個不同的步驟：

  1. 使用傳統DDR或撥號程式配置檔案配置DDR。在實施備份配置之前，請驗證DDR連線是否正常工作。

  2. 配置路由器，使其在主鏈路出現故障時啟動DDR連線。此配置使用備份介面觸發撥出。有關其他選項的詳細資訊，請參閱評估備份介面、浮動靜態路由和Dialer Watch for DDR Backup。

組態

本文檔使用如下所示的配置。

此配置使用BRI電路備份串列鏈路。此配置還在兩台路由器之間使用開放最短路徑優先(OSPF)路由協定。啟用備份連線後，必須確保更新路由表以使用新的備份路由。

驗證客戶端maui-soho-01(1600)的配置中的以下點：

  • 使用環回地址。這樣使用OSPF的路由器ID將不會更改，並且備用鏈路可以在啟用後建立對等體。

  • 撥號器負載閾值設定為低。如果不需要128k多鏈路備份連線，可以更改此值。

  • 任何IP流量都會觸發撥號(基於dialer-list 1和dialer-group 1)。 由於備份鏈路需要相關流量來撥號備份鏈路，因此請確認您確實有生成相關流量的流量源。在此示例中，OSPF hello資料包將觸發撥號。如果不使用路由協定，可以使用ICMP ping撥號備份鏈路。根據需要調整感興趣的流量。

  • 使用OSPF。您可以使用任何所需的路由協定。只需確保路由協定中包含主介面網路和備用介面網路。如果您希望使用靜態路由而不是路由協定，請建立一個靜態路由，其中下一跳是遠端bri介面（根據場景，您可能必須將它設定為浮動靜態路由）。

驗證伺服器maui-nas-05(3640)的配置中的以下點：

  • 為遠端站點配置撥號器對映語句。錯誤的撥號器對映語句可能導致連線的備份鏈路出現路由問題。

  • 所有IP流量均定義為關注流量。這將重置空閒超時並保持連線，直到主裝置恢復運行。如果您不需要釘住備份鏈路，則可以更改此情況。

驗證

本節提供的資訊可用於確認您的組態是否正常運作。

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

  • show interface bri0 — 這表示BRI介面是否啟動。如果主鏈路為up，則BRI介面將處於standby。只有當主鏈路關閉時，BRI介面才會啟動。

  • show isdn status — 使用此入口以確保路由器與ISDN交換機正確通訊。在輸出中，驗證第1層狀態是否為ACTIVE，以及是否顯示第2層狀態狀態= MULTIPLE_FRAME_ESTABLISHED。此命令還顯示活動呼叫的數量。

show ip route輸出示例

主鏈路正常運行的客戶端maui-soho-01(1600)的路由表如下所示： 

maui-soho-01#show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area 
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
       i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area

O       172.22.1.1 [110/65] via 192.168.10.1, 00:00:23, Serial0

上面顯示的show ip route輸出顯示了使用主鏈路(serial 0)從對等體獲取的OSPF路由。 現在，我們關閉主連結並啟用備份連結。

注意：在主介面上發出shutdown命令不會導致備份BRI進行撥號。如果您發出shutdown命令來關閉主連線，則Cisco IOS軟體不會自動啟動備份連線。您必須通過拔下電纜或某種等效的方法來物理關閉主連線，才能啟用備用介面。

啟用備份鏈路後，將交換OSPF表並安裝使用備份鏈路的新路由。流量現在通過備份鏈路傳輸。下面是一個示例： 

maui-soho-01#show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area 
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
       i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
       * - candidate default, U - per-user static route, o - ODR

疑難排解

本節提供的資訊可用於對組態進行疑難排解。

疑難排解指令

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。

注意：發出debug指令之前，請先參閱有關Debug指令的重要資訊。

  • debug dialer — 用於檢視按需撥號路由資訊。

  • debug isdn events — 用於檢視ISDN介面使用者端發生的ISDN活動。

  • debug isdn q931 — 這顯示呼叫建立和ISDN網路連線（第3層）的斷開，可用於隔離問題。

  • debug ppp negotiation — 此命令顯示協商PPP元件(包括鏈路控制協定(LCP)、身份驗證和網路控制協定(NCP))時有關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。

  • 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。
