1查看IGMP的接口信息
[R2]display igmp interface
Interface information of VPN-Instance: public net GigabitEthernet0/0/0(10.1.1.252): IGMP is enabled Current IGMP version is 1 //版本为1 IGMP state: up IGMP group policy: none IGMP limit: - Value of query interval for IGMP (negotiated): - Value of query interval for IGMP (configured): 60 s //查询间隔时间为60s Value of other querier timeout for IGMP: 0 s Value of maximum query response time for IGMP: -最大查询响应时间不能设置为10s Querier for IGMP: 10.1.1.253 //查询路由器优选IP地址最大的 Total 1 IGMP Group reported
【技术要点1】查询器的选举原则机制
1、依赖PIM选举接口IP地址大的路由器
2、只有查询器才会发送general query
3、查询器与非查询器均能收到报告报文生成IGMP表项
