3 配置步驟

3.1  配置SW1的IP地址和互聯路由

<H3C>system–view

#新建互聯VLAN10

[H3C]vlan 10

#將10口加入到VLAN10

[H3C]interface Ethernet1/0/10

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

[H3C-Ethernet1/0/10]quit

#配置交換機間互聯地址

[H3C]interface Vlan-interface10

[H3C-Vlan-interface10]ip address 172.16.10.1 255.255.255.0

[H3C-Vlan-interface10]quit

#配置與組播源互聯地址

[H3C]interface Vlan-interface1

[H3C-Vlan-interface1]ip address 192.168.1.1 255.255.255.0

[H3C-Vlan-interface1]quit

#配置組播源與組播客戶端互聯路由

[H3C]ip route-static 192.168.2.0 255.255.255.0 172.16.10.2

 

3.2  SW1上開啟組播路由功能，接口下使能PIM DM

#開啟組播路由功能

[H3C]multicast routing-enable

#設備互聯接口使能PIM-DM功能

[H3C]interface Vlan-interface10

[H3C-Vlan-interface10]pim dm

[H3C-Vlan-interface10]quit

#連接組播源接口使能PIM功能

[H3C]interface Vlan-interface1

[H3C-Vlan-interface1]pim dm

[H3C-Vlan-interface1]quit

[H3C]save

配置SW2的IP地址和互聯路由

<H3C>system–view

#新建互聯VLAN10

[H3C]vlan 10

#將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

#配置交換機間互聯地址

[H3C]interface Vlan-interface10

[H3C-Vlan-interface10]ip address 172.16.10.2 255.255.255.0

[H3C-Vlan-interface10]quit

#配置與組播客戶端互聯地址

[H3C]interface Vlan-interface1

[H3C-Vlan-interface1]ip address 192.168.2.1 255.255.255.0

[H3C-Vlan-interface1]quit

#配置組播源與組播客戶端互聯路由

[H3C]ip route-static 192.168.1.0 255.255.255.0 172.16.10.1

 

3.3  SW2上開啟組播路由功能，設備互聯接口使能PIM-DM，組播接受者接口使能IGMP

#開啟組播路由功能

[H3C]multicast routing-enable

#互聯接口接口使能PIM-DM功能

[H3C]interface Vlan-interface10

[H3C-Vlan-interface10]pim dm

[H3C-Vlan-interface10]quit

#連接組播客戶端接口使能IGMP功能

[H3C]interface Vlan-interface1

[H3C-Vlan-interface1]igmp enable

[H3C-Vlan-interface1]quit

[H3C]save

 

3.4  檢查配置結果

 

組播源：

通過使用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

 

 

 

組播客戶端：

通過使用display pim  routing-table命令查看SW2 PIM路由表信息。

<H3C>dis  pim  routing-table

 VPN-Instance: public net

 Total 2 (*, G) entries; 1 (S, G) entry

 

 (*, 225.0.0.1)
