查询词典 routing

Routing tables are continuously built and rebuilt by intelligent discovery protocols, such as Routing Information Protocol or Open Shortest Path First. Each router/'s routing table shows the best route to the destination address; for addresses that may be several hops away, it shows the best next－hop router.疯狂英语学习网 e37.com.cn
