1) 组播路由器启用组播功能:ip multicast-routing 2) 在相应的接口启用PIM协议:ip pim dense-mode 连接PIM路由器的接口 第一跳路由器连接组播源的接口 最后一跳路由器连接接收者的接口 3)配置接收主机加入某个组播组:ip igmp join-group 239.1.1.1 验证命令: R1#show ip pim interface 查看路由器哪些接口启用P...
1、启用IP组播路由功能 Router(config)#ip multicast-routing 2、接口运行PIM-SM Router(config-if)#ip pim sparse-mode 3、更改向上游发送Join/Prune的间隔 Router(config-if)#ip pim message-interval seconds 静态RP: ip pim rp-address ip-address [ACL] 手工指定RP的IP地址,ACL中可以限制成为哪些组的RP ...
An interface is included in an IGMP routing entry only when PIM is not enabled on the interface. The IGMP routing table increases the number of available outbound interfaces for multicast routing entries. The following is an example of an IGMP routing entry: <HUAWEI> display igmp routing-table...
R2 floods it back to R1. We now have a multicast routing loop. We can prevent this by implementing the RPF check: When a router receives a multicast packet on an interface, it looks at the source IP address and does two checks: Do we have an entry that matches the source address in...

A multicast router creates an MLD group entry when it receives an MLD Join message from a host. The router maintains group memberships of MLD group entries and instructs a multicast routing protocol, usually the Protocol Independent Multicast (PIM) protocol, to create corresponding (*, G) entrie...
