multicast troubleshooting

In previous articles, we have explained the content of the IPv6 protocol. We should remember that in IPv6, there are unicast IPv6 routing protocols and IPv6 multicast routing protocols. Now let's take a look at the latter. What content does the IPv6 Multicast Routing Protocol contain? Let's take a look at the following content. IPv6 Multicast Routing Protocol IPv

Broadcasting sends broadcast information to a node regardless of whether a node is in a specified group, this can easily

can be an IP datagram, or it can be a shard of an IP datagram.Broadcast and multicastThere are three types of IP addresses: unicast addresses, broadcast addresses, and multicast addresses.Broadcast and multicast are only applied to UDP, and they are important for applications that need to transmit messages to multiple receivers at the same time. TCP is a connection-oriented protocol that means that there i

. The subnets can be divided into four subnets (,). On average, each subnet is 2 ^ 6-2 = 62, because the first subnet requires 100 instances, the subnet is divided into one A subnet contains 100 hosts. Therefore, the binary system requires at least seven host numbers. Because the default subnet mask is 255.255.255.0, The subnet mask is 255.255.255.255.128 and the IP address is 192.168.15.1 ~ 192.168.15.127 A single subnet has 60 hosts. Therefore, the binary system requires at least six host numb

Technorati labels: CISCO, multicast, multicast, RPF, CCIE RPF, reverse path forwarding. It is an important foundation for multicast forwarding. Only after successful RPF detection can multicast traffic be correctly forwarded in the network. When you query the keyword "cisco rpf detection mechanism and working principle

One disadvantage of broadcast is that it affects all computers in the subnet, even if they are not interested in this broadcast message. Multicast can solve this problem. Multicast adopts Promotion Technology(Browsing Web pages is a drawing technology, and also a pushing technology.EmailService). Multicast is also called

The following is reproduced from: http://www.enet.com.cn/article/2011/0705/A20110705880890.shtml I. Introduction to the topology structure of the networkThe structure of the network consists of three layers: the core layer, the aggregation layer and the access layer.The core layer consists of 5 core nodes (each core node is configured with a routing switch CiscoCatalyst6509), which is interconnected via gigabit fiber to an incomplete mesh structure.The aggregation layer consists of 53 nodes (one

IPv6 provides many high-quality service functions, especially the multicast technology, which changes the traditional transmission mode of data streams and overcomes the shortcomings of unicast and broadcast. Modern distance education can use these advanced functions to promote its own development. (1) feasibility of applying IPv6 Multicast technology to Modern Distance Education 1. The coverage rate of dis

MulticastUnlike the one-to-one transmission over the network, it is a one-to-many (at least one) point based on UDP/IP point transmission protocol, The multicast router uses the IGMP protocol to check whether the multicast group receiver exists in the network segment connected to each interface, that is, the group members. If a member exists, the multicast router

IP multicast (also called multicast or multicast) technology allows one or more hosts (Multicast sources) to send a single packet to multiple hosts (once and simultaneously) TCP/IP network technology. Multicast, as a one-to-multiple-point communication, is one of the effec

In the network overuse phase, we will use the dual-stack technology to connect the two networks. In the double stack technology, IPv6 multicast provides powerful functions. It can run on both the router and host, and can write v4 and v6 to form a convergence point. In transition technology, IPv6 multicast is very important. We will discuss this in depth. IPv6 multicast
