簡介

本文檔提供了具有多個BRI介面的路由器的配置示例，該路由器撥打具有多個BRI介面的路由器，並建立多鏈路PPP(MPPP)連線。撥號的路由器必須確定遠端BRI上不再有可用通道，然後撥打下一個遠端BRI電話號碼以建立其他通道。

兩台路由器都使用撥號器配置檔案繫結物理BRI介面。您還可以使用撥號器旋轉組配置此設定，如使用旋轉組為多個BRI配置MPPP中所述。

有關撥號程式設定檔的詳細資訊，請參閱設定和疑難排解撥號程式設定檔。

請注意Cisco 3640(melanie)配置中的以下幾點：

  • 該配置使用撥號器配置檔案。BRI介面是撥號器池的成員。特定於目標的所有配置設定均在介面撥號器2配置中配置。

  • 撥號器介面有兩個撥號器字串。請記住，遠端路由器上有兩個BRI介面(torito)。 由於這些BRI未在Telco的尋線組中配置，因此路由器melanie必須單獨撥打每個BRI。使用多個撥號器串時，第一個電話號碼總是被撥打。只有當呼叫失敗時，撥號器介面才會嘗試第二個撥號器字串。我們可以根據需要定義許多按順序使用的撥號器字串。

  • MPPP的撥號器負載閾值設定為1，這是最小值。該值可根據您的流量模式和要求更改。但是，如果定義更高的負載閾值，則只有在負載超過該定義時才新增其他連結。有關如何控制將通道新增到多重連結套件組合中的詳細資訊，請參閱調節和可選命令一節。

  • 遠端路由器的靜態主機路由指向介面撥號器2。然後將流量從池的物理成員（BRI 2/1和BRI 2/2）轉發出去。 為應使用多鏈路連線的目標流量建立靜態路由（或使用路由協定）。

調整和可選命令

您可以使用本節中的命令調整MPPP連線的行為。您可以通過仔細調整此類引數來控制成本，這樣有助於避免資料鏈路的浪費和不必要的使用。這些命令必須在發起撥號的一側實施。

  • dialer load-threshold load [outbound |入站 |任一]???您可以配置MPPP，以便在主通道建立後立即啟動其他通道。在這種情況下，請在dialer load-threshold load命令中將load threshold設定為1。因此，會調出其他通道，這些通道將繼續保持（即，它們不會翻動）。 如果負載閾值設定為較高值，則多個通道可能會基於鏈路上的負載翻動。如果您希望根據需要新增其他通道，請根據流量將負載閾值設定為介於1和255之間的適當值。例如，如果附加通道將達到總容量的50%，則閾值應設定為128(0.50*255)。

  • ppp timeout multilink link remove seconds???使用此命令可防止負載變化時多鏈路連線抖動。例如，當負載閾值設定為15（即，15/255 = 6%）且流量超過閾值時，就會出現額外的線路。當流量低於閾值時，會丟棄額外的線路。在資料速率具有高度可變性的情況下，有利的是多通道保持運行指定時間段，即使負載閾值低於指定值。將此多鏈路超時分配給小於dialer idle-timeout指定的時間，該時間控制所有鏈路的超時。

  • ppp timeout multilink link add seconds???使用此命令可防止向MP捆綁包新增多個鏈路，直到在指定間隔內接收到高流量。這可防止突發流量不必要地增加線路。

  • dialer max-link number ???要指定撥號程式配置檔案可以隨時啟動的遠端目標的最大鏈路數，請在介面配置模式下使用dialer max-link命令。在本例中，我們在melanie上為撥出配置了兩個BRI（或四個B通道）。因此，預設情況下，所有四個通道都在MPPP連線中啟動。但是，如果只想建立三個B通道，則可以使用dialer max-link命令限制鏈路數。

驗證

本節提供的資訊可用於確認您的組態是否正常運作。

show命令

使用以下命令驗證連線：

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-???示路由器是否與ISDN交換機正確通訊。在輸出中，您需要驗證第1層狀態是否為ACTIVE，並顯示第2層狀態是否為MULTIPLE_FRAME_ESTABLISHED。此命令還顯示活動呼叫的數量。有關詳細資訊，請參閱使用show isdn status命令進行BRI故障排除。

  • show ppp multilink -???示有關處於活動狀態的多鏈路捆綁包的資訊。使用此命令驗證多鏈路連線。

  • show dialer [interface type number]顯???為DDR配置的介面的常規診斷資訊。如果撥號器正常啟動，Dialer state is data link layer up消息必須出現。如果顯示實體層啟動，則表示線路通訊協定已啟動，但網路控制通訊協定(NCP)未啟動。發起撥號的資料包的源地址和目的地址顯示在撥號原因行中。此show命令還會顯示計時器的配置以及連線超時之前的時間。

  • show caller user username detail???顯示特定使用者的引數，例如分配的IP地址、PPP和PPP捆綁引數等。如果您的Cisco IOS版本不支援此命令，請使用show user命令。

show命令輸出

show ppp multilink命令會顯示連結連線後每台路由器上多重連結套件組合的成員。請注意，在路由器melanie上，套件組合名稱是torito，而在路由器torito上，套件組合名稱是melanie。還指出了屬於該捆綁的BRI介面和B通道。

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

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 -???示有關撥號器介面上接收的資料包的DDR調試資訊。此資訊有助於確儲存在可以使用撥號器介面的相關流量。

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

  • debug ppp negotiation???在協商鏈路控制協定(LCP)、身份驗證和網路控制協定(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。進行LCP協商時，會建立諸如最大接收重建單元(MRRU)等多鏈路引數。

  • debug ppp authentication -???示PPP身份驗證協定消息，包括CHAP資料包交換和口令身份驗證協定(PAP)交換。

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

debug指令輸出

有關如何對每個BRI的多鏈路進行故障排除的資訊，請參閱排除ISDN BRI鏈路上的第二個B通道呼叫故障。當您在1個BRI（2個b通道）上擁有多鏈路功能時，可以將BRI新增到捆綁包中。

啟用疑難排解命令一節中描述的調試，然後ping遠端路由器的地址。ping必須啟動撥號並連線到遠端路由器。每個附加鏈路啟動後，都會將其新增到MPPP捆綁包中。
