cured to the network card, which is generally non-changing. The IP address is usually assigned automatically by the network administrator or the system.3, the traditional switch can only split the conflict domain, cannot split the broadcast domain, and the router can split the broadcast domainNetwork segments connected by switches still belong to the same broadcast domain, and broadcast packets propagate across all network segments connected to the s

Differences among hubs, switches, routers, reconnections, gateways, and bridges 1. a hub, also known as a HUB, works on the first layer of the OSI Layer-7 structure and is a shared-bandwidth device, receives data broadcast. Generally, the LAN uses a Star Connection topology, and each workstation is connected to a hub. Because of the bandwidth sharing feature of the hub, the network utilization efficiency is

Large home computers can be heard, switches and routers, routers have been seen and used, the switch does not know what kind of thing, this article mainly explain the difference between the two. Limited home routers, corporate routers you can not use, use will be used, the

The management of the equipment is the basic condition for maintaining the normal operation of the equipment, so let's take a look at some basic management commands and methods of Cisco routers and switches. The methods and commands for managing routers and switches are mainly divided into several areas: 1, understan

In the process of using OpenStack, we encounter the creation of virtual machine routers, switches, etc.1. What is their role in the end?Why is 2.DHCP produced, and what is its role? Personal Summary:Switches: Generally used in the same network segment, working at the data link layer, for example we are in the same office, then the switch is used.Routers are used in different network segmentsIn other words,

At present, the development of routers, switches and hubs is very rapid, and the technology is more standardized and mature. First, the HUB, that is, the HUB. Its function can be simply understood as connecting some machines to form a LAN. The switch, also known as the switch-type hub, works basically the same as the hub. However, there is a difference between the two in terms of performance: the hub uses t

uses a VLAN, and a VLAN is also available on the cliff. Linghu rushed to the cliff and Don't be sad. Finally, the world is quiet. Relying on the router of Zuo Leng Chan, Ling Hu Chong can still give it to Xiao Shimei on the Internet every day. Tell stories and chat. The introduction of LAN switches enables dedicated bandwidth between network nodes. However, for layer-2 broadcast packets, layer-2 Communication Broadcast on each network node. At the sa

domain. broadcast packets are transmitted across all CIDR blocks connected to the vswitch. In some cases, communication congestion and security vulnerabilities may occur. The CIDR blocks connected to the vro are allocated to different broadcast domains, and the broadcast data does not pass through the vro. Although vswitches above Layer 3 Have VLAN functions and can also be divided into broadcast domains, communication between subbroadcast domains is not allowed, and communication between them

continue transmission). Because it is in a "center" position on the network, the hub is also called the hub. The hub works very simply, for example, with a 8-port hub that connects 8 computers. The hub is in the "center" of the network, the signal is forwarded through the hub, and 8 computers can connect and exchange with each other. The specific communication process is this: if Computer 1 is going to send a message to computer 8, when the network card of the Computer 1 delivers the informati

on the table items. ② If there is no table entry corresponding to this IP address in the ARP table, the router sends a broadcast frame and sets the destination MAC address of the frame header to ffffffffffff. After the switch receives the frame, if the target MAC address is ffffffffff, the frame will be forwarded from all ports (except the ports that send the frame). When the computer receives the frame, the IP address and MAC address are sent to the router, so that the router generates an ARP
