1 配置需求或说明

1.1  适用产品系列

本案例适用于如SS5500-20TP-SI、S5500-52C-EI、S5500-52C-PWR-EI、S5500-34C-HI、S5800-32C-EI、5800-32F、S5800-60C-PWR、S5830-106S等S5500、S5800、S5830系列的交换机。

1.1 配置需求

公司内部部署了一台组播源，为保证终端能正常接收组播源传输的业务，需在所经交换机上开启组播功能。

3 配置步骤

3.1  配置SW1的IP地址和互联路由

<H3C>system–view

#新建互联VLAN10

[H3C]vlan 10

#将10口加入到VLAN10

[H3C]interface Ethernet1/0/10

[H3C-Ethernet1/0/10]port access vlan 10

[H3C-Ethernet1/0/10]quit

#配置交换机间互联地址

[H3C]interface Vlan-interface10

[H3C-Vlan-interface10]ip address 172.16.10.1 255.255.255.0

[H3C-Vlan-interface10]quit

#配置与组播源互联地址

[H3C]interface Vlan-interface1

[H3C-Vlan-interface1]ip address 192.168.1.1 255.255.255.0

[H3C-Vlan-interface1]quit

#配置组播源与组播客户端互联路由

[H3C]ip route-static 192.168.2.0 255.255.255.0 172.16.10.2

 

3.2  SW1上开启组播路由功能，接口下使能PIM DM

#开启组播路由功能

[H3C]multicast routing-enable

#设备互联接口使能PIM-DM功能

[H3C]interface Vlan-interface10

[H3C-Vlan-interface10]pim dm

[H3C-Vlan-interface10]quit

#连接组播源接口使能PIM功能

[H3C]interface Vlan-interface1

[H3C-Vlan-interface1]pim dm

[H3C-Vlan-interface1]quit

[H3C]save

配置SW2的IP地址和互联路由

<H3C>system–view

#新建互联VLAN10

[H3C]vlan 10

#将10口加入到VLAN10

[H3C]interface GigabitEthernet 1/0/10

[H3C-GigabitEthernet1/0/10]port access vlan 10

[H3C-GigabitEthernet1/0/10]quit

#配置交换机间互联地址

[H3C]interface Vlan-interface10

[H3C-Vlan-interface10]ip address 172.16.10.2 255.255.255.0

[H3C-Vlan-interface10]quit

#配置与组播客户端互联地址

[H3C]interface Vlan-interface1

[H3C-Vlan-interface1]ip address 192.168.2.1 255.255.255.0

[H3C-Vlan-interface1]quit

#配置组播源与组播客户端互联路由

[H3C]ip route-static 192.168.1.0 255.255.255.0 172.16.10.1

 

3.3  SW2上开启组播路由功能，设备互联接口使能PIM-DM，组播接受者接口使能IGMP

#开启组播路由功能

[H3C]multicast routing-enable

#互联接口接口使能PIM-DM功能

[H3C]interface Vlan-interface10

[H3C-Vlan-interface10]pim dm

[H3C-Vlan-interface10]quit

#连接组播客户端接口使能IGMP功能

[H3C]interface Vlan-interface1

[H3C-Vlan-interface1]igmp enable

[H3C-Vlan-interface1]quit

[H3C]save

 

3.4  检查配置结果

 

组播源：

通过使用display pim  routing-table命令查看SW1 PIM路由表信息。

dis  pim routing-table

 VPN-Instance: public net

 Total 0 (*, G) entry; 1 (S, G) entry

 

 (192.168.1.100, 225.0.0.1)

     Protocol: pim-dm, Flag: LOC ACT

     UpTime: 00:00:17

     Upstream interface: Vlan-interface1

         Upstream neighbor: NULL

         RPF prime neighbor: NULL

     Downstream interface(s) information:

     Total number of downstreams: 1

         1: Vlan-interface10

             Protocol: pim-dm, UpTime: 00:00:07, Expires: never
