route is valid. B. Measures: If the next hop is valid, the routing protocol selects the best path to the given parent's location, and provides it to the routing table, according to the principle of minimum measure value. C. Management distance: If you know from different routing sources that multiple routes to the same network (their prefixes are the same), the router will decide which route to add to th

People tend to think that computer technology is a high technology, but TCP/IP has appeared in various forms over the past thirty years and is ubiquitous. Therefore, the TCP/IP protocol has time to become more mature and more stable and reliable. However, when it comes to computers, things are not that simple. When the route pa

command line commands. Not necessarily easy to understand. Some require professional knowledge, while hardware routers use Web GUI to set up, emphasizing user friendly and making simple and easy-to-understand setting methods based on specific functions.8. level differences. There is no difference between software routers. The performance depends on the PC and software selected by the publisher. Therefore, different network/route applications may not

be considered as the simplest dual-Ethernet router and a four-port small switch, and its Wan port is connected to the Internet, the LAN port is connected to the Intranet for differentiation. A route is the act of transmitting information from the source to the destination. In terms of image, the information package is like a person who wants to go to a specific location. routing is the process of selecting a path for this person. The

In terms of routers, protocols are a key point. Protocol learning can help us better configure and manage vrouters. As the basis, we should understand the RIP Protocol. The RIP routing protocol is mainly a routed-based program. At the same time, routed runs on Unix systems. When the RIP routing protocol is enabled on the network, the network has a powerful function to automatically update the route table. However, some major internal gateway protocols

Ways to add routes under Linux:One: Use the route command to addRoutes added using the route command, the machine restarts, or the network card restarts, the route is invalidated, by:Routes added to the host# route add–host 192.168.168.110 Dev eth0# route Add–host 192.168.16

TCP/IP protocols have appeared in various forms over the past thirty years and are ubiquitous. Therefore, the TCP/IP protocol has time to become more mature and more stable and reliable. However, when it comes to computers, things are not that simple. When a route package passes through the network, an error may occur. In this case, it is very helpful to be familiar with the Windows route table. The
