1. A layer 2 switch is designed to perform Layer 2 functions, while a layer 3 switch performs both Layer 2 and Layer 3 functions (routing). 2. Layer 2 switches are less expensive and more efficient than layer 3
This is not a simple Layer 2 switch and router superimposed. Layer 3 routing modules are directly superimposed on the high-speed backplane bus of Layer 2 switching, breaking through the interface rate limit of traditional routers, and the rate can reach tens of Gbit/s. Together with backplane...
2 years ago @bras02, does it mean that although I have made same configuration for both layer 2 and layer 3 switch ( i.e configuring Vlan 10 and 20 on same interface ), the behaviour depends on Control Plane and Data plane of layer 2 and layer 3 switch? LikeReply bras02 2 years ...
In the previous example where the L2 switch is connected to a L3 switch the packets would come in and go out of the trunk port connecting the L2 switch to the L3 switch. In your original example where everything is in vlan 10 if one of the PCs connected to the switch did aa telnet...
THIRDLAYER SWITCH实现跨网段通信的过程如下：ARP请求与回复：当站点A想要与不在同一子网内的站点B通信时，它会向其“缺省网关”发送ARP请求。三层交换机接收到这个广播后，会回复包含交换机VLAN的MAC地址信息给站点A，并在硬件表项中存储站点A的IP、MAC和连接端口数据。数据包发送与接收：站点A收到ARP...
2. 市场需求持续增长： 随着数字化转型的加速和云计算、大数据等新兴技术的普及，企业对高效、可靠的网络基础设施的需求日益增长。三层交换机以其卓越的性能和经济性，正好迎合了这一市场需求。3. 技术创新推动发展： 技术创新是三层交换机持续发展的重要驱动力。随着技术的不断进步，三层交换机的功能将...
Configure interface-based VLAN assignment on the switch for Layer 2 forwarding. Configure the router as the gateway of users to implement Layer 3 forwarding across network segments through sub-interfaces or VLANIF interfaces. Configure the router as the DHCP server to assign IP addresses to users....
