When a router receives a packet on an interface, the router reads the network portion of the logical address of the corresponding destination in the package, and then finds it in the routing table.

Static routing The concept of static routing (1) The most original configuration of the route, pure manual, easy to manage, but time-consuming, generally used in small enterprises or middle-down enterprises (2) The disadvantage of static routing is not to dynamically reflect the network topology, when the network topology changes, the administrator must manual

unreachable. RIP is visible only for small internet use. rip cannot use multiple routes between the two networks at the same time. RIP selects a route with the fewest routers, which is the shortest path, even if there is another high-speed (low-latency) router with more routes. Three points of RIP protocol Exchange information only with neighboring routers. The information exchanged is all the information that is currently known to the router as its own

Static routes), and some tests are dynamically acquired (called Dynamic routing). A direct-attached route belongs to a static route.The router is working on the network layer, and the logical address can be identified at the network layer. When a router receives a packet on an interface, the router reads the network portion of the logical address of the corresponding destination in the package, and then finds it in the

this by representing the target and subnet masks in binary notation. A binary subnet mask consists of a series of 1 representing the destination network address portion and a series of 2 parts representing the destination host address portion. View the target to determine whether the host address portion of the target (as defined by the subnet mask) is set to 1. Only the Windows NT 4.0, Windows 2000, Windows Millennium Edition, and Windows XP route commands support the-p parameter. The route c

When a router receives a packet on an interface, the router reads the network portion of the logical address of the corresponding destination in the package, and then finds it in the routing table.

sends each packet received to all output lines except for the line that the packet arrives at. In the future there will be multiple groups of replicas arriving at the destination, the first to arrive, probably the "best" path.3. Traffic-based routing algorithmsConsidering both the topological structure and the network load, the average data flow between each pair of nodes is relatively stable and predictable, and the average packet delay can be obtai

It was suggested (for example, me) to organize the long conflict list into a trie tree form in a massive routing
