difference between layer2 and layer 3 switch

adjacent network segment can belong to different virtual networks, while the two segments which are far apart may belong to different virtual networks, while the two segments which are far apart may belong to the same virtual network. The terminals in different virtual networks cannot communicate with each other, which enhances the access control of the data within the network. The difference between a third tier

Two-tier switch:The second layer switching technology is more mature, two layer switch is a data link layer device, can identify the MAC address information in the packet, according to the MAC address to forward, and these MAC addresses and corresponding ports recorded in their own internal table of addresses. Specific

information can be composed of virtual network of ports to the three-tier switch, because the number of ports can be arbitrarily specified, the transmission bandwidth between the subnet is unlimited. 2. Reasonable allocation of information resources: due to access to the resource rate in the subnet and access to the global network, there is no difference in resource rate, the subnet set up a separate serve

The layer-3 switch you know works like this. It works like a layer-3 switch. Why do we say that the L3 forwarding performance of a layer-3

Configuration example of cisco router and layer-3 Switch environment, cisco layer-3 SwitchSimple environment configuration instance for cisco router layer-3

Example: 3026 2012 5012. The value of 2nd bits is 0 ~ 4 indicates that it is a layer-2 switch. 3550. The fifth digit is 5 ~ 9 indicates that it is a layer-3 switch. LI (LitesoftwareImage) indicates that the device is a weak feature version. SI (StandardsoftwareImage) i

1,Layer-3 forwardingYesRoute information is requiredThe route selection in the forwarding process determines the final egress of the message,L3 SwitchJust put thisRoute functions are integrated into the switch ChipGo. 2,Route SelectionExistExact matchAndLongest matchTwo methods. 2.1,Exact matchThat is, the destination IP address and the route address information

when he cannot find the address, and the hub is only responsible for forwarding the email regardless of the Bounce Message. Vro A Router operates at the network layer, the third layer in the OSI Layer-7 network model. It works by removing the information of the second layer (data link

of using Server Load balancer to improve the scalability, availability, and manageability of Server clusters. This chapter mainly discusses the deployment of Server Load balancer and several solutions for deploying Server Load balancer in the existing network. We will also discuss how to design highly available solutions to implement fault tolerance for different network components throughout the network, including Load balancer. Before discussing the network structure, we need to understa

Performance Tests on layer-2 and layer-3 vswitches with 24 ports and all-gigabit vswitches have encountered many problems recently. Experts have said that QoS ensures port congestion, high-priority data is processed first. It makes sense to improve the utilization of 24 fully-gigabit switches with insufficient bandwidth. Three-tier competition

Experts tell you what a layer-3 switch is. Now every household has their own computer and understands what a layer-3 switch is. At that time, the layer-

, as the core of the network, there is no substantial breakthrough in the router technology that acts as the interconnection between networks. Therefore, a new routing technology came into being-layer-3 switching technology, which is a routing technology because it works on the layer-3 network protocol, the two-

Layer-3 Switch: the principle of layer-3 switch is that two hosts A and B Using IP addresses communicate with each other through the layer-3

Layer-3 switches are quite common, So I studied how to correctly select the layer-3 Switch. Here I will share it with you, hoping it will be useful to you. The current vswitches generally have the "routing" function, which makes it hard for many enterprise users to figure ou

Experiment on single-arm routing using a layer-3 Switch In the real environment, sometimes the gateway is not necessarily enabled on the router, sometimes the single-arm routing function is not necessarily connected to the interface on the router, you can use a layer-3

In today's society, the most commonly used vro is the number of routers, because it is relatively cheap and its functions are no different from those of vswitches. However, layer-3 vswitches are indeed more powerful than vrouters, then we will study the layer-3 switch. Many
