I am eager for the first time to switch between vlan routing and nat addresses of Cisco switches. I am very energetic and have an undefeated spirit. I am ready to continue to answer questions during multiple rounds of interviews. My little brother squashed his eyes and took out the bottom of the press box: If my company has two Internet interfaces, A and B, respectively. The following vswitch divides multiple VLANs. One of the VLANs goes through the-l

frame, view the source address (host a) and add it to the MAC address table. However, the switch does not know which port the Host B is on (MAC Address table does not have the MAC address of Host B), so this frame is an unknown unicast frame. The swap opportunity floods this frame.1.3 Group Network Diagram1.4 Stream Table AnalysisIn promiscuous mode, the policy Bridge flow table is similar to the "... actions=normal", which does not differentiate the traffic and can be forwarded as normal.When

Explanation of VLAN principles that Tom can understand (1) Why VLAN? 1. What is a VLAN? VLAN (Virtual LAN), translated into Chinese as "Virtual LAN ". A lan can be a network composed of a few home computers or an enterprise network composed of hundreds of computers. A VLAN

After VLAN is divided on a vswitch, computers in the VLAN cannot communicate with each other. Layer-3 devices are required for Inter-VLAN communication. We can use a router to implement this function. If you use a router, the single-arm routing mode is usually used. In practice, most of the routes between VLANs are implemented through layer-3 switches. layer-3 sw

Early Stage In the early days, a vswitch was only a physical device and had no logic functions or IP addresses. It forwards data packets like a hub. The only advantage is that it does not live in a large conflict domain like a hub, causing a traffic accident all day long. 　　 Differences between VLANs and CIDR blocks: CIDR blocks are IP address segmentation specifications, which are private CIDR blocks, and which are public CIDR blocks, the number of available IP addresses in each CIDR block.

Huasai firewall implements single-arm routing to implement inter-VLAN communication network equipment: One USG2130, several S2700 switches www.2cto.com customer requirement: VLAN division on the switch and single-arm routing on USG2130, at the same time, mutual access is required between the three CIDR blocks, and the three CIDR blocks can be connected to the INTERNET. Because the USG2130 has only one layer

[Lab name]Implement VLAN across vswitches[Background description]Assume that a company has two departments: Sales Department, Technical Department, and sales department. The Personal Computer System of the sales department is connected to different switches, and the two Departments need to communicate with each other. However, for the sake of data security, the sales department and the technical department need to be isolated from each other, and appr

[Cisco] DHCP relay, layer-3 Switch VLAN Routing PracticeThe experiment topology uses the GNS3 0.8.6 simulator to build a DHCP server using Red Hat 6.5. The experiment requires configuring a layer-3 Switch VLAN routing so that VLAN10 and VLAN20 members can access each other. Performs DHCP relay for layer-3 switches so that VLAN10 and VLAN20 members can obtain IP addresses through the DHCP server. Tutorial pr
