Hands-on practice of Linux VLAN-playing with OpenStack (13) every five minutes) This section describes how to implement and configure the following VLAN network in the experiment environment. Configure VLAN Edit/etc/network/interfaces and configure eth0.10, brvlan10, eth0.20, and brvlan20.Vmdiff is used to demonstrate modifications to/etc/network/interfaces.

Three-layer switching technology is two-layer switching technology and three-layer routing forwarding technology, the traditional exchange technology in the data link layer to operate, three-layer switching technology is the network layer to implement high-speed packet forwarding. The third layer switching technology can realize the function of network routing, and the optimal network performance according to different network conditions. The most important purpose of the three-tier switch is to

We know that the traditional LAN Ethernet adopts the CSMA/CD method with conflict detection. In the CSMA/CD network, nodes can use the network whenever they have data to be sent. Before a node transmits data, it performs a "listener" to check whether the network is busy. If not, the node starts to transmit data. If the network is in use, the node waits. If the two nodes do not hear anything and start to use the line at the same time, a conflict will occur. When sending data, if it uses a broadca

We all know that DHCP is a service for IP address management. In some network changes, we also need to modify the settings. Here we will explain how to configure the multi-vlan dhcp service. All aspects must be taken into account when upgrading the network, and how to implement the DHCP service in a multi-VLAN environment is one of them. Multi-vlan dhcp service s

Objective Docker as the hottest lightweight container technology at present, there are many commendable features, such as Docker mirroring management. However, Docker also has many imperfect places, the network aspect is the Docker relatively weak part. Therefore, it is necessary for us to have an in-depth understanding of Docker's network knowledge to meet the higher network requirements. Docker Network mode selection At present, many articles have introduced the network model of Docker, but

We know that the DHCP service is not able to work in multiple VLANs, so by default, DHCP and VLANs cannot coexist, and the broadcast information emitted by DHCP clients cannot be broadcast across multiple VLANs, and when the client is dispersed across multiple VLANs, Broadcast data failed to send because the client could not be found. How to solve this problem? Configuring a DHCP server for each VLAN is the easiest way to do it, but it's less efficien

The actual example of a VLAN configuration is very simple, just like the eth-switch routing method through VLAN. First, let's look at a method with high hardware efficiency: Port1 ~ 4 As the access port and the user mode on the hardware, that is, the packets sent from the PC to these ports do not carry VLAN-tag. After the SW hardware receives the packets, based o

Fix after "Go" testSuccessfully let IVM run a number of VLANs, add a can carry multiple Vlanid network card, Nativevlan is the compromise method of transformation, if not like this method, with---Delete multi-vlan Nic method, in general, Lpar can only and IVM in the same network segment, I have a study, Success has allowed IVM to run multiple VLANs. The steps are as follows: first, change the blade's built-in switch settings to find the appropriate in

This document introduces how to divide 802.1Q VLANs based on examples.Example: as shown in the preceding figure, the marketing department and product department of a company set up network isolation. The two departments can access the Internet and servers of their respective departments, but mutual access between departments and servers of other departments is prohibited.In this example, the actual topology and port connection effect are as follows. This article describes how to divide VLANs bas
