Original link http://louisnetwork.blog.sohu.com/111972027.html Some tests involve IGMP snooping at work. When it comes to IGMP snooping, it is inevitable that IGMP proxy will come to mind. Sometimes, you may think more and think more about it.What is the difference between

At present, in the IP network, the operator's network to provide more services for the purpose, no longer in the form of xDSL to provide users, but directly provide a unified width interface, in some broadband community this form is particularly common. At present, in the broadband community to apply the most in addition to Internet services, more is to provide IPTV applications. In the promotion of IPTV, for the involved access layer switching equipment, the device is generally required to supp

multicast group is found locally, the proxy will send an application to the upstream router and create a multicast group locally. When a multicast member exits, the proxy also checks whether other multicast members exist in the multicast group. If yes, then, it only deletes the members applying to withdraw from the multicast group. Otherwise, it notifies the upper-end router to cancel the multicast group. Therefore, the above two application solutions have their own advantages and disadvantages

network C-BSR, router A after the 130s boot timer expires, become BSR, at 60s intervals to the network to announce bootstrap messages; If there is a competition C-BSR in the network, router A will compare priority (priority equality compared IP address greater priority), if the priority is low, Router A resets the boot timer to continue listening if priority high Router a becomes BSR after the 130s boot timer expires. Visible high-priority C-BSR can preempt, preemption delay of 130s.Problem 2:1

Huawei S5720 three layer switch (Huiju), a two-layer switch (S5700) for the company Jieru, and two laptops with VLC installed Media Player.1) The whole network routing can be reached between RP_BSR and Huiju through OSPF;2) RP_BSR and Huiju establish PIM SM neighbor, note: RP_BSR F0/1 must open PIM, otherwise RP_BSR can not forward the group broadcast text;3) RP_BSR configuration c-rp for 224.0.0.0/4, C-BS

Take a look at the diagram below, L2 switch turns on IGMP snooping,router1 is a remote multicast router that forwards multicast packets with the PIM protocol. PIM, Protocol-Independent Multicast is a family of multicast routing protocols that can provide one-to-many and many-to-many distribution of data over the Internet. The "protocol-indepen
