VLAN intercommunication is achieved through layer-3 switching. Generally, routers are rarely used within an enterprise network. In a production environment, inter-VLAN communication is mainly implemented through layer-3 switching. A layer-3 Switch provides the network layer function to enable VLAN mutual access. It uses the routing function of the layer-3 Switch to identify the IP address of the data packet and find the route table for Route Selection and forwarding. For cross-VLAN routing in a

Bo friends asked, "How to configure the three-tier switch to create a VLAN" This issue, I refer to other books and the network above some information on the simple introduction. The following descriptions are based on the Cisco Switch VLAN. Cisco's VLAN implementations are typically port-centric, and the port connected to the node determines the VLAN on which it resides. There are two ways to assign a port to a VLAN, which is static and dynamic, respectively. The process of forming a static VL

The Windows2008 is configured as a DHCP server, assigning IP addresses to six VLANs, respectively, if the VLANs are: A:192.168.1.0/24 B:192.168.2.0/24 ..... F:192.168.6.0/24Core switch for Cisco 3560 The setting needs to be done in two ways:1.cisco3560 three-layer switch requires port setting command on Vlana Interface Vlana IP address xxxx xxxx IP helper-address "

However, people often associate VLAN with layer-3 Switching layer-3 Switching. It is believed that layer-3 switches must be introduced after VLAN division. By setting Access Listing on layer-3 switches or routers, VLANs can communicate with each other. This is necessary in some enterprise campus networ

VLAN (Virtual Local area Network), which is built on the basis of Ethernet interaction technology, can divide the same physical network into multiple valn, or cross the physical network barrier, and divide users from different subnets into the same VLAN. Figure 2 is an example of a VLAN partition. Figure 2 There are many ways to implement VLANs, and there are generally two types of VLAN partitioning based on switching devices: L Switch-based port p

Today we are sharing a question about MDT2010 deploying windows7 across VLANs. This is a real case of work, when this problem was encountered, the mind flashed is to set the IP Helper address command on the switch, but because there is no permission to abandon this direction of thinking, and the solution to the DHCP server.There are no strangers to DHCP servers, and the options in the server option are difficult to implement in the actual work.Everyon
