Cisco router configuration manual Virtual LAN (VLAN) routing

Cisco router configuration manual Virtual LAN (VLAN) routing 1. The main network technology we currently use when constructing an enterprise network is generally based on exchange and virtual networks. The exchange technology changes shared media to exclusive media, greatly improving the network speed. The Virtual Network Technology breaks the restrictions of the geographical environment. without changing the physical connection of the network, the workstation can be moved between Working Groups or subnets, And the workstation can form a logical Working Group or virtual subnet, improve the operation performance of information systems, balance network data traffic, and make rational use of hardware and information resources. At the same time, the use of virtual network technology, greatly reduce the burden of network management and maintenance work, reduce network maintenance costs. With the application of the virtual network technology, the question of how to communicate between virtual networks is inevitable.
2. Interior Switching Link (ISL) protocol is used to implement VLAN relay between switches. It is an information packet marking protocol. Frames sent on ISL interfaces are composed of a standard Ethernet frame and related VLAN information. As shown in, data from different VLANs can be transmitted on interfaces that support ISL. Iii. Virtual LAN (VLAN) routing instance. Example 1:
The device uses the ipvst5500 switch 1, the installation of WS-X5530-E3 Management Engine, multiple WS-X5225R and WS-X5302 Routing Switching Module, The WS-X5302 is directly inserted into the switch, through two channels and the VLAN on the system back board connected, from the user's point of view, it is regarded as a one-interface module, which supports ISL. There are three virtual networks in the vswitch, respectively named default, qbw, rgw, virtual network routing through WS-X5302. Set system name 5500C is the command to be set.

Example 2: The switch device still uses the ipvst5500 switch 1, install WS-X5530-E3 Management Engine, multiple WS-X5225R in the switch has three virtual network, respectively named default, qbw, rgw, use the Cisco3640 router to implement the inter-network routing. The vswitch settings are similar to Example 1. The Cisco3640 router is equipped with a NM-1FE-TX module with a fast Ethernet interface that supports ISL. The Cisco3640 Fast Ethernet interface is connected to a port supporting isl on the vswitch, for example, 3rd interfaces (1st ports) in vswitch 3/1 slot ). Router # wri tBuilding configuration...
