8. How do I connect to a 10 m network with a long distance?
When connecting a 10 m network that exceeds m to M, there are usually three methods in the project:
1) Use a repeater. Use a thin cable, plus 3 ~ Up to 500 m for the four reconnections. If it is a twisted pair, you can use the HUB) to extend the transmission distance, but up to 180 m.
can be used for backbone connections or for wide-area connections between campus networks and regional network centers. When selecting a vro, pay attention to the network interfaces supported by the vro。, such as FDDI, UTP, BNC, and AUI, as well as the number of ports and supported protocol types. In addition, some routers provide good protocol control, traffic statistics, bandwidth allocation, and other functions. Vro configurations can be imported

Different data link layers define different network and Protocol features, including physical addressing, network topology, error verification, frame sequence, and traffic control. The physical addressing (corresponding to the network addre
Routers play an important role in computer networks and serve as a bridge between computer networks. It not only connects to different networks, but also selects data transmission paths and blocks illegal access.
Router configuration is not very easy for beginners. We will introduce general configurations and simple debugging of routers for your reference When configuring routers. This article uses cisco2501 as an example.

If you configure multiple IP addresses on a network card, you cannot use the ifconfig command, but you can only see the last configured master IP address, therefore, the ifconfig command output is not very reasonable.
