for Route Selection and forwarding. Layer-3 switches use direct connection routes to achieve mutual access between different VLANs. Layer-3 switches configure IP addresses for interfaces and use SVI (exchange virtual interfaces) to interconnect VLANs. SVI refers to creating virtual interfaces for VLANs in a vswitch an

pipeline, multiple distributed forwarding engines can quickly send data packets independently. In a single pipeline, multiple ASIC chips simultaneously process multiple frames. This concurrency and pipeline improves the forwarding performance to a new level: On-Demand Unicast, Broadcast, and Multicast on all ports. 3. dynamically Scalable Memory For advanced LAN switching products, the real performance is built on an intelligent storage system.

Generally, the price of a third-level switch is around 10000 yuan, while that of a gigabit-level router is within the "" range.In addition to cost-effective, layer-3 vswitches have scalable lines

performance is built on an intelligent storage system. The layer-3 Switch directly associates a portion of the memory with the forwarding engine. More interface modules are added, including their respective forwarding engines, and memory is also expanded accordingly. It also uses streamlined ASIC processing to dynamically construct the cache, which increases the

indispensable for connecting subnets If the number of computers on the same network exceeds a certain number, usually around 200, depending on the communication protocol), it is likely that the network transmission efficiency will be low due to a large number of broadcasts on the network. To avoid a broadcast storm caused by broadcasting on a large vswitch, You can further divide it into multiple virtual network VLANs ). However, this will cause a problem: Communication Between VLANs must be im

However, traditional routers cannot perform communication tasks between VLANs, because the Routing Capability of traditional routers is too weak compared with the network traffic of LAN. In addition, the price of a gigabit router is unacceptable. If you use a layer-3

Therefore, the use of VLAN in the initial design of the network can bring great benefits to the future expansion of the network.VLAN partitioning by routers is a cost-effective method in small and medium-sized enterprises. However, VLAN partitioning by routers seriously affects the network performance of enterprises, therefore, layer-3 switches with routing functions are widely used in VLAN netwo

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
