PIM组播协议稀疏模式（SM模式）

【实验名称】

PIM组播协议稀疏模式（SM模式）

【实验目的】

熟悉如何配置PIM稀疏模式

【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的稀疏模式来实现。

【实现功能】

实现PIM稀疏模式下组播流量的传输，只有请求加入组才能获得组播流量

【实验拓扑】

【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 S1

S1(config)#vlan 10 ! 创建一个vlan10

S1(config-vlan)#exi

S1(config)#vlan 12

S1(config-vlan)#exi

S1(config)#vlan 20

S1(config-vlan)#exi

S1(config)#vlan 30

S1(config-vlan)#exi

S1(config)#vlan 100

S1(config-vlan)#exi

S1(config)#interface f0/24

S1(config-if)#switchport mode trunk ！把f0/24接口作为trunk接口

S1(config-if)#switchport trunk allowed vlan remove 100 ! trunk链路不传输vlan 100的信息

S1(config)#interface vlan 1

S1(config-if)#ip address 192.168.1.253 255.255.255.0

S1(config-if)#no shutdown

S1(config)#interface fastethernet f0/12

S1(config-if)#switchport access vlan 12

switch(config)#hostname S2

S2(config)#vlan 12

S2(config-vlan)#exi

S2(config)#vlan 50

S2(config-if)#no shutdown

S2(config)#interface vlan 60

S2(config-if)#ip address 192.168.60.1 255.255.255.0

S2(config-if)#no shutdown

S2(config)#interface fastethernet f0/1

S2(config-if)#switchport access vlan 50

S2(config)#interface fastethernet f0/2

S2(config-if)#switchport access vlan 60

S2(config)#interface fastethernet f0/12

S2(config-if)#switchport access vlan 12

switch(config)#hostname S2126

S2126(config)#vlan 10

S2126(config-if)#switchport access vlan 10

S2126(config)#interface f0/2

S2126(config-if)#switchport access vlan 20

S2126(config)#interface vlan 1

S2126(config-if)#ip address 192.168.1.254

S2126(config)#interface fastethernet 0/24

S2126(config-if)#switchport mode trunk

switch(config)#hostname S2150

S2150(config)#vlan 50

S2150(config-vlan)#exi

S2150(config)#vlan 60

S2150(config-if)#ip address 192.168.2.254

S2150(config)#interface fastethernet 0/24

S2150(config-if)#switchport mode trunk

第二步：配置路由协议

S1(config)#router ospf ! 开启ospf进程

S1(config-router)#network 192.168.1.0 0.0.0.255 area 0 ！将网段加入到区域0

S1(config-router)#network 192.168.10.0 0.0.0.255 area 0

S1(config-router)#network 192.168.12.0 0.0.0.255 area 0

S1(config-router)#network 192.168.20.0 0.0.0.255 area 0

S1(config-router)#network 192.168.30.0 0.0.0.255 area 0

S1(config-router)#network 192.168.100.0 0.0.0.255 area 0

S2(config)#router ospf

S2(config-router)#network 192.168.2.0 0.0.0.255 area 0

S2(config-router)#network 192.168.12.0 0.0.0.255 area 0

S2(config-router)#network 192.168.50.0 0.0.0.255 area 0

S2(config-router)#network 192.168.60.0 0.0.0.255 area 0

第三步：配置组播

S1(config)# ip multicast-routing ！开启组播功能

S1(config)# ip pim rp-address 192.168.30.1 ！静态指定RP

S1(config)#interface vlan 1

S1(config-if)#ip pim

S1(config-if)#ip pim sparse-mode !设置PIM模式为SM模式

S1(config)#interface vlan 10

S1(config-if)#ip pim

S1(config-if)#ip pim sparse-mode

S1(config)#interface vlan 12

S1(config-if)#ip pim

S1(config-if)#ip pim sparse-mode

S1(config)#interface vlan 20

S1(config-if)#ip pim

S1(config-if)#ip pim sparse-mode

S1(config)#interface vlan 100

S1(config-if)#ip pim

S1(config-if)#ip pim sparse-mode

S2(config)# ip multicast-routing

S2(config)# ip pim rp-address 192.168.30.1

S2(config)#interface vlan 1

S2(config-if)#ip pim

S2(config-if)#ip pim sparse-mode

S2(config)#interface vlan 12

S2(config-if)#ip pim

S1(config-if)#ip pim sparse-mode

S2(config)#interface vlan 50

S2(config-if)#ip pim

S2(config-if)#ip pim sparse-mode

S2(config)#interface vlan 60

S2(config-if)#ip pim

S2(config-if)#ip pim sparse-mode

S2126(config)#ip igmp profile 1 ！进入igmp配置文件模式

S2126(config-profile)#deny ！ 允许所有的组播组通过。

S2126(config)# ip igmp snooping svgl profile 1

S2126(config)# ip igmp snooping svgl ！设置为svgl模式

S2126(config)# ip igmp snooping svgl vlan 1 mrouter learn pim-dvmrp ！动态学习路由连接口

S2126(config)# ip igmp snooping svgl vlan 10 mrouter learn pim-dvmrp

S2126(config)# ip igmp snooping svgl vlan 20 mrouter learn pim-dvmrp

S2126(config)# ip igmp snooping source-check port ! 源端口检测，默认打开。

S2150(config)#ip igmp profile 1

S2150(config-profile)#deny

S2150(config)# ip igmp snooping svgl profile 1

S2150(config)# ip igmp snooping svgl

S2150(config)# ip igmp snooping svgl vlan 1 mrouter learn pim-dvmrp

S2150(config)# ip igmp snooping svgl vlan 50 mrouter learn pim-dvmrp

S2150(config)# ip igmp snooping svgl vlan 60 mrouter learn pim-dvmrp

S2150(config)# ip igmp snooping source-check port

验证测试：组播接收端可以接收组播流量

【注意事项】

l 默认PIM的模式是DM模式,要改变DM模式为SM模式

l 要配置静态的RP地址

l 在二层交换机上要设置igmp snooping 的模式为svgl
