VLAN lab questions: Answer Process (1) full connectivity between devices with the same VLAN 1. Create vlan2 and vlan3 on SW1 and sw2 respectively. The command is as follows: SW1 # VLAN DatabaseSW1 (VLAN) # VLAN 2 2. Route the corresponding interfaces to the corresponding

As a new generation of network technology, VLAN provides a good solution to the problems of flexible configuration of network sites and network security, the following describes how to update a VLAN on a layer-3 switch. The filter service is used to set boundaries to restrict Frame Forwarding between members of different VLANs and between different protocols using a single MAC address and a group of MAC add

Many people may not have a special understanding of setting policy routes. So I have studied VLAN-Based Configuration Policy routes. Here I will share with you, hoping to help you. With the popularization of networks, how can small-sized enterprise local networks spend less money to implement more complex network functions in the case of a shortage of funds to meet people's needs for higher network functions, it is a concern of network technicians. In

from a group of MAC addresses. GMRP transmits such group information between vswitches on the Internet, so that vswitches can update their filtering information to implement extended service functions. A vswitch has the filtering service and extended filtering service without any configuration. Because the old vswitches, hubs, and routers do not support dynamic multicast address filtering, the corresponding ports connected to them need to be configured with extended filtering. The switch filter

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

Learning essentials-the most comprehensive summary of VLAN learning notes (Free Download !) (It's a pity)-Linux Enterprise Application-Linux server application information. The following is a detailed description. [I = s] This post was last edited by ytitxw Recently, I have prepared my VLAN study notes, summarized all the knowledge points, and packaged them into pdf files for you to download and read.

Secrets: how to configure a VLAN on a vswitch When configuring a VLAN in a virtual LAN, I will introduce the VLAN configuration in the article, we will provide you with a learning direction for relevant knowledge. 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

After we have a detailed understanding of DHCP, we also know that it also has some service settings in the applications of a variety of routers and switches. Here we will focus on the configuration of dhcp relay. This time, we will explain the content of the dhcp server corresponding to the vlan interface configuration. ◆ Dhcp relay Configuration Dhcp relay configurations include: Configure the dhcp server corresponding to the

The IPS VLAN Group is a IPS6.0 feature, where VLAN group blending mode requires a VLAN tag when configuring mirroring, which is not the default in GNS, and VLAN group online mode is an overlay of online mode and VLAN group. Configure the online interface pair first, then con

Voice VLAN concept and networking concept: the so-called voice vlan uses vlan to identify a packet as a Voice packet, and the packet carries voice data. In networks where voice messages and data packets coexist, vlan-based voice packets are identified to distinguish voice messages and data packets, and a higher priorit

Switch Port vlan mode Ø the Acess port receives a packet to determine whether there is any VLAN information: If there is no vlan information, the PVID of the port is entered and the switch is forwarded. If yes, the packets are discarded directly (default) Ø send packets on the Acess port: the VLAN information of the pa

Inter-VLAN RoutingMulti-layer switch between VLANs ip Address: 1. for local or end-to-end VLANs, the recommended number of hosts in a single vlan is 100-200.2. for layer-3 point-to-point interfaces, we recommend that you use a 30-bit mask when designing the p level. Devices that implement vlan routing: 1. any layer-3 Switch 2. any external router with interfaces

Three-layer switching technology: two-layer switching technology + three-layer forwarding technology. It solves the network segment in the LAN, the network segment must rely on the router to manage the situation, to solve the traditional router low speed, complexity caused by the bottleneck problem.650) this.width=650; "Src=" Http://s1.51cto.com/wyfs02/M01/84/63/wKioL1ePKkTAgqs8AACyLCFWuCA902.png-wh_500x0-wm_3 -wmp_4-s_366222421.png "title=" three-layer switching

, and completely using ASIC hardware to achieve routing and switching at line speed, the latter represents the fast ip of 3com, and the virtual fast Security Network of cabletron. The method used is to route the network at the first layer, then, the second layer switches the end-to-end network stream data group. This is the policy of "one route, then switch. The powerful functions of the layer-3 Exchange router are as follows: (1) routes are calculated based on the L3 protocol. The supported ro

In the two-layer network, when transmitting two beginning, it needs to be forwarded with the outer VLAN of the message, while the outer tag of the user network is usually inconsistent with the VLAN of the carrier network, so the VLAN stacking and VLAN mapping and dot1q tunnel etc. Unlike
