IP PIM Sparse-Dense-Mode IPPIMSparse-Dense-Mode2011-01-3015:09:57|分类：CISCO|标签：rpsparsedensemodepim|字号大中小订阅. 最近在研究Multicast,觉得很有意思，因为它完全不同于Unicast的各种协议，虽然也有MOSPF是基于OSPF开发的，但是整个组播树的建立以及包转发都跟OSPF是不同的。 谈到组播，就必须得谈...
pim dense-mode , sparse-mode , ssm dense-mode 多播router之间用的是pim协议,host与多播router之间用的是IGMP协议,dense-mode是router收到multicast traffic之后,首先会检查下进端口的那个multcast source地址是否在IP TALBE上对应那个端口,如果对应,然后就四散到其他端口,如果有些机器不要的,会在收到后发送拒绝信...
Dense mode 采用推方式传送多播信息,假定所有的网络节点都是接收者,然后再修剪掉向那些不需要多播信息的网络的转发,Flood & Prune 的行为每隔几分钟就要发生一次。 Sparse mode 采用拉方式传送多播信息,除非接收端显式的声明,否则将不会向其发送多播数据。 注意:鉴于Dense mode周期性的Flood行为对网络影响较大,实际的...
The 'ip pim sparse-dense mode' command enables PIM to operate in sparse or dense mode, depending on the multicast group. When you enable sparse-dense mode, the interface is treated as dense mode if the multicast group is in dense mode. If the group is in sparse mode, the interface is...
My question is why is an RP always needed in sparse-dense-mode whether through Auto-RP or statically. It seems like regular client multicast traffic would fall back to dense mode if there wasnt an RP enabled. Although, I know its not considered as efficient, multicast traffic should still ...
The invention discloses a device for realizing protocol independent multicast (PIM) in a sparse mode and a dense mode, which relates to a multicast routing protocol in network communication, in particular to the device for the multicast routing protocol of the PIM (Protocol Independent Multicast)....

This paper focuses on building up some models for its most common types, this is, PIM Dense Mode and PIM Sparse Mode, by using manual algebraic derivations, following the Algebra of Communicating Processes (ACP) axioms. The purpose of such models is to achieve a simplified approach, yet as...
dense-mode是最简单的,无需RP选举,在global模式输入ip multicast-routing,然后在各端口输入ip pim dense-mode即可。 一个节点路由器会通过igmp来发现下游到底还要不要这种multicast,不要的话会马上通知上游节点别发多播信息来了。而再上一级的路由器收到这个拒绝信息之后,是不是永远都不再发多播信息来呢?不是的,...
