PIM组播协议密集模式

PIM组播协议密集模式（DM模式）【实验名称】 PIM组播协议密集模式（DM模式）【实验目的】 熟悉如何配置PIM密集模式【背景描述】 你是一个某单位的网络管理员，单位有存放资料的组播服务器，服务器为用户提供组播服务，请你满足现在的网络需求。采用PIM的密集模式来实现。【实现功能】 实现PIM密集模式下组播流量的传输，如果没有组成员，自动修剪组播发送信息。【实验拓扑】 S1 vlan1:192.168.1.253 vlan10:192.168.10.1 vlan12:192.168.12.1 vlan20:192.168.20.1 vlan100:192.168.100.1S2 vlan1:192.168.2.253 vlan50:192.168.50.1 vlan12:192.168.12.2 vlan60:192.168.60.1S2126 vlan1:192.168.1.254 S2150vlan1:192.168.2.254【实验设备】 S3550-24(2台)、S2126G（1台）、S2150G(1台)、PC(4台)【实验步骤】 第一步：基本配置switch(config)#hostname S1S1(config)#vlan 10 !
