(This is a more comprehensive example, as can be seen from the topology diagram, the equipment and technologies it includes. The following explains this example. For internal LAN, Cisco's Catalyst6506 is used as the core switch, and Catalyst3500 is used for secondary switching. At the same time, in order to illustrate Trunk, a Catalyst2900 is added as a tertiary switch, and a Catalyst1900 switch is used for terminal connection, so that Catalyst6506 and Catalyst3500 Trunks are built between Catalyst3500 and Catalyst2900 to implement VLAN across switches. Note: If the Catalyst2900 series is to implement Trunk, the software must be the enterprise version. For external connection, it is mainly dedicated line connection and dial-up access, of course, there are many types. Including DDN, ISDN, FrameRelay, E1 lines, etc. This example shows the basic configuration of the device. For the connection problem of multiple devices, it is worth noting the routing problem. In this example, the external connection part adopts static routing and the internal LAN adopts dynamic routing. In the frame relay configuration of this example, IPUnnumbered is used, which can save address resources. Interested can pay attention.
