配置PIM-SM组播网络示例组网需求在如图1所示的ISP网络中部署组播业务。已知该网络中已经部署了完备的IGP，单播运行正常，并接入Internet。要求通过在S9300上进行适当配置，使网络中的用户主机能够通过组播方式接收视频点播信息。图1配置PIM-SM典型组播网络组网图S9300物理接口VLANIF接口IP地址S9300-AGE1/0/0VLANIF100192.168.9.1/24 GE2/0/0VLANIF10110.110.1.1/24 GE3/0/0VLANIF200192.168.1.1/24S9300-BGE1/0/0VLANIF300192.168.2.1/24 GE2/0/0VLANIF10210.110.2.1/24

1.在S9300的所有接口上使能PIM-SM功能。使能PIM-SM功能之后才能配置PIM-SM的其他功能。说明：如果该接口下还需要配置IGMP协议，必须先使能PIM-SM，才能使能IGMP协议。两者顺序不能颠倒，否则PIM-SM功能配置会不成功。2.在与主机侧相连的S9300接口上使能IGMP。接收者能通过发送IGMP消息自由加入或者离开某个组播组。叶结点S9300通过IGMP协议来维护组成员关系列表。3.在与直连用户主机的S9300接口上使能PIMSilent，防止恶意主机模拟发送PIMHello报文，增加组播路由器的安全性。说明：该功能仅适用于与用户主机网段直连的S9300接口，且该用户网段只与这一台S9300相连。4.配置RP。在PIM-SM网络中，RP是RPT树的根节点。建议RP的位置配置在组播流量分支较多的设备上，如本图中的S9300-E的位置。说明：·用户侧的DR得到新的IGMP成员关系创建(*,G)表项后，向RP发送加入/剪枝消息，沿路更新共享树。·组播数据源刚开始向组发送数据时，由其DR向RP单播发送注册消息，RP将其解封装后沿共享树分发给其组成员，同时RP向组播源侧DR发送注册-停止消息。注册停止后，可以由RPT向SPT切换。5.（可选）在与Internet相连的接口上配置BSR边界，BSM消息不能通过该边界，使BSR只为该PIM-SM域服务，增加组播可控性。6.（可选）在各S9300上设置SSM组地址范围。使PIM-SM域内的S9300只为SSM组地址范围内的组播组服务，实现可控组播。说明：配置步骤中，只列出了与PIM-SM配置相关的命令。 数据准备为完成此配置举例，需要准备如下数据：·组播组G地址：225.1.1.1/24。·组播源S地址：10.110.5.100/24。·S9300接口和用户主机之间运行的IGMP版本号为3。·SSM组地址范围：232.1.1.0/24。操作步骤1.配置各接口的IP地址和单播路由协议。#按照图1配置各S9300接口的IP地址和掩码，配置各S9300之间采用OSPF进行互连，确保网络中各S9300之间能够在网络层互通，并且之间能够借助单播路由协议实现动态路由更新。具体配置过程略。接口IP地址的配置方法，请参见《QuidwayS9300T比特路由交换机配置指南-基础配置》中配置接口的IP地址，OSPF的配置方法，请参见《QuidwayS9300T比特路由交换机配置指南-IP路由》中OSPF配置。2.使能组播功能，在各接口上使能PIM-SM功能。#在所有S9300上使能组播功能，在各接口上使能PIM-SM功能。S9300-B、S9300-C、S9300-D和S9300-E上的配置过程与S9300-A上的配置相似，配置过程略。[S9300-A]multicastrouting-enable[S9300-A]interfacevlanif101[S9300-A-Vlanif101]pimsm[S9300-A-Vlanif101]quit[S9300-A]interfacevlanif100[S9300-A-Vlanif100]pimsm[S9300-A-Vlanif100]quit[S9300-A]interfacevlanif200[S9300-A-Vlanif200]pimsm[S9300-A-Vlanif200]quit 1.在连接用户主机的接口上使能IGMP功能。#在S9300-A连接用户主机的接口上使能IGMP功能。S9300-B和S9300-C上的配置过程与S9300-A上的配置相似，配置过程略。[S9300-A]interfacevlanif101[S9300-A-Vlanif101]igmpenable[S9300-A-Vlanif101]igmpversion32.在S9300-A接口上使能PIMsilent。3.[S9300-A]interfacevlanif101[S9300-A-GVlanif101]pimsilent4.配置RP。说明：配置RP有两种方式：静态RP和动态RP两种。可以同时配置，也可以只配置其中一种。同时配置两种RP时，可以通过参数调整优先选择哪种RP。本实例同时配置两种RP，并通过参数配置，优选动态RP，静态RP作为备份。#配置动态RP需要在PIM-SM域的一个或多个S9300上进行如下配置。本例中在S9300-E上配置RP通告的服务范围，及C-BSR和C-RP的位置。[S9300-E]aclnumber2008[S9300-E-acl-basic-2008]rulepermitsource225.1.1.00.0.0.255[S9300-E-acl-basic-2008]quit[S9300-E]pim[S9300-E-pim]c-bsrvlanif100[S9300-E-pim]c-rpvlanif100group-policy2008priority0#配置静态RP需要在所有S9300上配置。S9300-B、S9300-C、S9300-D和S9300-E上的配置过程与S9300-A上的配置相似，配置过程略。说明：
