Routerinformation

Some routers only support a single protocol, but most routers can support the transmission of multiple protocols, that is, multi-protocol routers. Since each protocol has its own rules, it is bound to reduce the performance of the router to complete the algorithms of multiple protocols in one router. The main job of a router is to find an optimal transmission path for each data frame passing through the router, and to efficiently transmit the data to the destination site. It can be seen that the strategy of selecting the best path, that is, the routing algorithm, is the key to the router. In order to complete this work, the relevant data of various transmission paths-Routing Table (Routing Table) is saved in the router for use in routing. The path table stores the information of the subnet flag, the number of routers on the network, and the name of the next router. The path table can be fixed by the system administrator.
