简介

本文档提供具有多个BRI接口的路由器的配置示例，该路由器通过多个BRI接口拨打另一台路由器，并建立多链路PPP(MPPP)连接。拨号的路由器必须确定远程BRI上没有更多可用的信道，然后拨打下一个远程BRI电话号码以建立其他信道。

两台路由器都使用拨号程序配置文件绑定物理BRI接口。您还可以使用拨号器循环组配置此设置，如使用循环组为多个BRI配置MPPP中所示。

有关拨号程序配置文件的详细信息，请参阅配置和故障排除拨号程序配置文件。

请注意Cisco 3640(melanie)配置中的以下要点：

  • 配置使用拨号程序配置文件。BRI接口是拨号程序池的成员。特定于目标的所有配置设置都在接口拨号器2配置中配置。

  • 拨号器接口有两个拨号器字符串。请记住，远程路由器(torito)上有两个BRI接口。 由于这些BRI未由Telco在寻线组中配置，因此路由器melanie必须单独拨打每个BRI。使用多个拨号程序字符串时，始终拨打第一个电话号码。仅当该呼叫失败时，拨号程序接口才会尝试第二个拨号程序字符串。我们可以根据需要按顺序定义尽可能多的拨号程序字符串。

  • MPPP的拨号器负载阈值设置为1，这是最小值。此值可以根据流量模式和要求进行更改。但是，如果定义了较高的负载阈值，则只有在负载超过该定义时才会添加附加链路。有关如何控制向多链路捆绑添加信道的详细信息，请参阅调整和可选命令部分。

  • 远程路由器的静态主机路由指向接口拨号器2。然后流量从池的物理成员（BRI 2/1和BRI 2/2）转发出去。 为应使用多链路连接的目标流量创建静态路由（或使用路由协议）。

调整和可选命令

您可以使用本节中的命令调整MPPP连接的行为。您可以通过仔细调整这些参数来控制成本，这有助于避免数据链路的浪费和不必要的使用。这些命令必须在发起拨号的端实施。

  • dialer load-threshold load[outbound |入站 |或]???？您可以配置MPPP，以便在主信道建立后立即出现其他信道。在这种情况下，将dialer load-threshold load命令中的load threshold值设置为1。因此，将启动附加信道，并且它们继续保持工作状态（即它们不摆动）。 如果负载阈值被设置为较高值，则多个信道可能会根据链路上的负载摆动。如果要根据需要添加附加信道，请根据流量将负载阈值设置为介于1和255之间的适当值。例如，如果附加信道要达到总容量的50%，则阈值应设置为128(0.50*255)。

  • ppp timeout multilink link remove seconds????？使用此命令可防止负载变化时多链路连接抖动。例如，如果负载阈值设置为15 (15/255 = 6%)，并且数据流超出阈值时，这时会出现其他线路。当流量低于阈值时，附加线路取消。在数据速率变化剧烈的情况中，多信道停留一段特定的时间则比较有益，即使负载阈值低于指定值。指定多链路超时低于控制所有链路超时的拨号程序空闲超时。

  • ppp timeout multilink link add seconds???？使用此命令可防止向MP捆绑添加多个链路，直到在指定间隔内收到高流量。这样可以防止突发 数据流引发额外的线路。

  • 要为拨号程序配置文件指定到远程目标（可以在任何时候启用）的最大链路数，请在接口配置模式下使用dialer max-link命令。在本例中，melanie上配置了两个BRI（或四个B信道），用于拨出。因此，默认情况下，所有四个信道都在MPPP连接中启动。但是，如果只希望启动三个B信道，则可以使用dialer max-link命令来限制链路数。

验证

本部分所提供的信息可用于确认您的配置是否正常工作。

显示命令

使用以下命令检验连接：

命令输出解释程序工具（仅限注册用户）支持某些 show 命令，使用此工具可以查看对 show 命令输出的分析。

  • show isdn status??？表示路由器是否与ISDN交换机正确通信。在输出中，您需要验证第1层状态为ACTIVE，并且显示第2层状态= MULTIPLE_FRAME_ESTABLISHED。此指令也显示活动的呼叫的数量。有关详细信息，请参阅使用show isdn status命令进行BRI故障排除。

  • show ppp multilink??？显示有关处于活动状态的多链路捆绑的信息。使用此指令验证多链路连接。

  • show dialer [interface type number]???？显示为DDR配置的接口的常规诊断信息。如果拨号器正常启动，则必须显示“拨号器状态为数据链路层启动”消息。如果物理层显示为up，则表示线路协议已启用，但网络控制协议(NCP)未启用。启动拨号的数据包的源地址和目标地址显示在 Dial reason line 中。此show命令也显示计时器的配置和连接超时前的时间。

  • show caller user username detail??？显示特定用户的参数，如分配的IP地址、PPP和PPP捆绑参数等。如果您的Cisco IOS版本不支持此命令，请使用show user命令。

show 命令输出

show ppp multilink命令显示链路连接后每台路由器上多链路捆绑的成员。请注意，在路由器melanie上，捆绑名称为torito，而在路由器上，捆绑名称为melanie。还指示属于捆绑的BRI接口和B信道。

故障排除

本部分提供的信息可用于对配置进行故障排除。

故障排除命令

注意：在发出debug命令之前，请参阅有关Debug命令的重要信息。

  • debug dialer???？显示有关拨号器接口上收到的数据包的DDR调试信息。此信息有助于确保存在可以使用拨号器接口的相关流量。

  • debug isdn q931??？显示ISDN网络连接（第3层）的呼叫建立和断开。

  • debug ppp negotiation??？显示PPP流量的信息，并在PPP流量协商链路控制协议(LCP)、身份验证和网络控制协议(NCP)时进行交换。成功的PPP协商将首先开放LCP状态，然后进行验证，最后进行NCP协商。当LCP协商进行时，会建立多链路参数，如最大接收重建单元(MRRU)。

  • debug ppp authentication??显示PPP身份验证协议消息，包括CHAP数据包交换和密码身份验证协议(PAP)交换。

  • debug ppp error???显示与PPP连接协商和操作相关的协议错误和错误统计信息。

debug 命令的输出

有关如何按BRI排除多链路故障的信息，请参阅排除ISDN BRI链路上的第二个B信道呼叫故障。当您在1个BRI（2个b信道）上获得多链路功能时，可以将BRI添加到捆绑包。

启用故障排除命令部分中描述的调试，然后ping远程路由器的地址。ping必须启动拨号并连接到远程路由器。当每个附加链路启动时，会将其添加到MPPP捆绑包。
