学习目的

·掌握静态RP和RP负载均衡的配置方法
拓扑图
图5-2 PIM SM及动态RP
场景
你是公司的网络管理员。公司以前使用过PIM的DM模式来实现组播路由学习，但是后来发现随着组播应用的发展，组播用户分部越来越广，这时组播质量显示出一定程度的下降。为了提高组播的可靠性、安全性和效率，你决定使用PIM的SM模式来实现组播路由学习。
在PIM的SM模式中，你需要定义RP，作为SM模式的共享树的树根。但是在实际的使用中，只是这样简单的配置是不够的，组播还需要实现RP之间的负载分担。
在实现网络的组播转发之前，你也遇到了一些网络故障，经过一些故障排除步骤，最终网络正常工作了。
学习任务
步骤一.基础配置与IP编址

[R2]multicast routing-enable
[R3]multicast routing-enable
[R4]multicast routing-enable

配置完成后，查看R1、R5和S1的PIM邻居学习的情况。
<R1>display pim neighbor

10.0.13.3 GE0/0/2 00:01:25 00:01:20 1 N

从命令输出结果可以看到，PIM协议已经在网络中正确运行。
步骤三.静态RP和静态RP负载均衡
通过给网络手动指定静态RP来控制网络中组播数据流。
在所有设备配置R1的S3/0/0接口作为网络中的静态RP。
[R1]pim
[R1-pim]static-rp 10.0.14.1
[R1-pim]quit
[R2]pim
[R2-pim]static-rp 10.0.14.1

[R5]pim
[R5-pim]static-rp 10.0.14.1
[R5-pim]quit
[S1]pim
[S1-pim]static-rp 10.0.14.1
[S1-pim]quit
S1模拟网络中组播用户接入的三层交换机，在S1的Loopback 0接口上开启IGMP功能。
[S1]interface LoopBack 0
[S1-LoopBack0]igmp enable
[S1-LoopBack0]quit
将S1的Loopback 0接口静态加入225.0.0.1组播组，模拟连接有225.0.0.1组播组的用户。
[S1]interface LoopBack 0
[S1-LoopBack0]igmp static-group 225.0.0.1
[S1-LoopBack0]quit
在R1、R4和S1上使用命令display pim routing-table查看PIM路由表。
[R1]display pim routing-table
VPN-Instance: public net

从命令输出结果可以看到，在指定静态RP的网络中，R1是网络中的RP。S1生成了一条经过R4到达RP路由器R1的组播路径。
创建ACL并应用到静态RP上，定义R1作为RP，服务的组播范围是225.0.0.0/24网段，定义R5作为RP，服务的组播范围是225.0.1.0/24网段。

从命令输出结果可以看到，S1针对225.0.0.1和225.0.1.1生成了二条组播路径。225.0.1.1组播路径经过R2到达RP路由器R5。
附加实验: 思考并验证
PIM的SM模式适合于用户比较分散的场景。
思考一下生活中哪些网络应用适合使用PIM SM模式的组播来实现数据转发？它们的特点是什么？
