Chapter Virtual LAN (VLAN) routing
a virtual LAN (VLAN)
the current structure of our enterprise network backbone network technology used are generally based on the exchange and virtual networks. Exchange of technology will be shared to exclusive media, the media, greatly improving the speed of the network. Virtual network technology to break the geographical constraints, without changes to the network physical connection to any of the circumstances in the working groups or sub station to move between workstations or virtual subnet logical working groups to improve the operation of information systems performance balancing network traffic, rational use of hardware and information resources. At the same time, the use of virtual network technology, greatly reducing network management and maintenance burden,asics gel kinsei 2, reduce network maintenance costs. With the virtual network technology, with the attendant must have to communicate in the virtual interconnection problems.
II, Inter-Switch Link (ISL) protocol
ISL (Interior Switching Link) protocol used to implement VLAN trunking between switches. It is an information packet marking agreement, in support of the ISL interface to send the frame by a standard Ethernet frame and the VLAN information associated with the composition. As shown below,tod's outlet, in support of the ISL of the interface can send data from different VLAN.
Third, virtual LAN (VLAN) routing instance
