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

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

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

As we all know, the vswitch ports are both layer-2 interfaces, and these interfaces are connected to physical ports. In a Vlan, these interfaces can be divided into access interfaces and relay ports. If the port of a vswitch uses an access port, it can only belong to a specific Vlan. If the port of a vswitch uses a relay port, it can belong to any Vlan. So when s

I have been learning cisco devices for a while and have never used them in the work environment. I am using a silly switch and adding an FW to the Internet. Considering that the unit is a domain environment, A three-tier switch will be added to the data center next year, and a two-tier switch will be added to the factory. Therefore, a virtual machine will be used to complete VLAN-based experiments in a single-domain environment. This will lay a founda
