vxlan vs vlan

Connect to the abovehttp://wangchunhai.blog.51cto.com/225186/1857192When using the vsphere virtual Datacenter, there are multiple virtual machines in the same network segment. Sometimes, the security policy does not allow these same network segments of the virtual machines to communicate with each other, this time you can use the "Private VLAN" function.5.1 Private VLAN IntroductionDedicated

CCNA Training Course (3) -- Vlan VTP relay single-arm route generation Tree Protocol This is the third day of the CCNA training course. There are many knowledge points on this day, and the experiment content is gradually becoming more complicated.VLAN A vswitch separates the conflict domains and the broadcast domains. A vro separates the conflict domains and the broadcast domains. In a pure exchange network, how do I divide broadcast domains? The answ

A typical LAN is to connect a core switch with a layer-3 Switch to several Branch switches (not necessarily with layer-3 switching ). We assume that the core switch name is com, and the Branch switches are par1, par2, and par3 respectively, which are connected to the core switch through the light module of port 1; assume that the vlan names are counter, market, and managing ...... Work to be done:1. Set vtp domain (both core and Branch switches)2. Co

The expansion of enterprise scale has created the continuous expansion of enterprise network scale, many enterprises in the expansion of the network scale used in the original network directly to increase the computer method to achieve, followed by the network system has become more and more complex, the network management has become increasingly difficult, the network security index has become increasingly low, and the utilization rate of network resources is greatly reduced, how to manage the

When I participated in the network engineering construction of some companies, I found that most of the company's choice of switches is still in the past, regardless of the enterprise intranet division based on subnets of different departments, generally, you only need to connect all the computers with a 10-ge switch. This requires dedicated enterprise-level traditional routers, such as CISCO 2600 series access routers, to access frame relay before ADSL and other broadband technologies are popul

The principle of Super VLAN aggregation, which is no longer difficult to understand, is also mainly used in the network of service providers to solve the shortage of IPv4 address resources. A Super VLAN is also known as VLAN Aggregation. The principle is to set a Super VLAN and multiple Sub VLANs (subvlans) association

* Vlan configuration ideas (access and Trunk) (1) create a Vlan and configure a static VLAN on an IOS-based switch: switch # vlandatabaseswitch (vlan) # vlanvlan-numnamevlan-nameswitch (vlan) # exitswitch # configureteriminalswitch (config) # interfaceinterfacemodulenu *

If we want to communicate between VLANs, we usually use the three layer switch or router sub-interface mode. Linux on the VLAN with Cisco switch relay connection, also can realize their communication with each other.Environment: RHEL 5.2 Minimized installation, physical NIC Eth1, trunk port connected as VLAN switch connected to 2960 GIGABITETHERNET0/1. Another physical NIC Eth0 as an upstream port, connecti

Virtual lan vlan) not only facilitates network security and prevents network storms, but also improves network operation efficiency and solves many other problems. The popularization of layer-3 switches creates conditions for VLAN applications. In the process of upgrading the network, I also used VLAN technology to solve the problem of network expansion. I.

I. Features of VLAN VLAN has the following features:Segmented, which can be divided into different network segments by department, function, and project;Flexibility: users who make up a VLAN do not need to consider the physical location of the thing. The same VLAN can also span multiple switches;Security: by separatin

First, the generation of Super VLAN backgroundIsolate-user-vlan successfully solved the problem of reducing the number of VLANs, and also realized the sharing of three-layer gateways to some extent. But it also has a problem with MAC address duplication that consumes MAC address table entries, and the technology itself belongs to a two layer VLAN technology.In a

Technical standards for VLANs IEEE 802.1Q was formally promulgated by IEEE Commissioners in June 1999, and the earliest Vlna technology was proposed by Cisco (Cisco) companies in 1996. With the development of the past few years, VLAN technology has been widely used in large and small enterprise networks, becoming the most popular Ethernet LAN technology at present. This article is going to introduce one of the most common switch technology application

The access port belongs to only 1 VLANs and is typically used to connect to a computer port. The port of the trunk type can be used for multi-VLAN communication. The hybrid type of port allows m

Troubleshooting of non-synchronous VLAN configuration information in VTP, vtpvlan VTP (VLANTrunk Protocol, VLANTrunk Protocol) is a dedicated Cisco VLAN used to maintain and manage dynamic VLANs (such as VLAN Based on MAC addresses, IP addresses, network protocols, and VLAN management policies).

Huawei s5700 switch vlan settingsCurrently, there are several Huawei s5700 switches, common switches, and tp-link routers. 1. The tp-link router connects to the Internet. 2. The s5700 switch divides vlan. 3. Common switches are connected to VLANs and PCs. The following figure shows the network topology. The s5700 has all vlan1 ports in vlan1.

Required knowledge:First, we should understand Catalsty 4908G-L3. In fact, it is a vro that uses the cisco ios configuration interface completely. By default, all interfaces are routable interfaces. Catalsty 4908G-L3 does not support L2 protocol, VLAN trunk protocol, dynamic trunk protocol, and port aggregation protocol. Catalsty 4908 does not support the following types: IOS 12.07-based1.

size, you might as well use a switch to create VLANs.Management of VLANsVLANs are inextricably linked to switched networks, but implementing VLANs will redefine the management environment. VLAN-defined logical domains involve possible views of the network, so the network management platform can display IP images, and sometimes images based on IPX are displayed. If you deploy a VLAN, its topology may not ma
