vlan segmentation

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
