PIM Sparse-Dense-Mode tsmarcyes Level 1 02-23-2010 06:41 PM - edited 03-06-2019 09:52 AM I can't seem to grasp the sheer concept of pim sparse dense mode. Documentation says that an enabled interface in pim sparse dense mode will use dense mode for dense groups and ...

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...

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,...
