Internet 组管理协议称为IGMP协议（Internet Group Management Protocol），是因特网协议家族中的一个组播协议。
该协议运行在主机和组播路由器之间。IGMP协议共有三个版本，即IGMPv1、v2 和v3。
1.在内核中添加支持
make menuconfig
Networking sopport----->
Networking options ----->
[*] IP : multicasting
[*] IP : multicast routing
[*] IP : multicasting
[*] IP : PIM-SM version 1 support
[*] IP : PIM-SM version 2 support
Networking sopport----->
Networking options ----->
[*]802.1d Ethernet Bridging
[*]IGMP/MLD Bridging
2.切换IGMP的版本号
[1]查看当前内核IGMP的版本号
#cat /proc/sys/net/ipv4/conf/eth0/force_igmp_version
#0
0 表示最高有效版本号，目前默认最高版本是V3。
[2]更改版本号
#echo "2" > /proc/sys/net/ipv4/conf/eth0/force_igmp_version
#cat /proc/sys/net/ipv4/conf/eth0/force_igmp_version
#2
3.使用QTDEMO发包测试
[1]测试demo链接
[2]配置本地ip进行发包
4.使用Wireshark进行抓包测试
[1]安装工具链接
[2]将board PC 通过交换机连成局域网。
[3]开始抓包
[4]抓到如下包时说明IGMP功能以实现。
