| 11.8.6 | How routers recognize networks
So how does route information get into a routing table in the first place? The network administrator can manually enter the information in the router. Or, routers can learn the information, on the fly, from each other. Manual entries in routing tables are called "static routes". Routes learned automatically are called "dynamic routes".
