Chapter 6. Routing Traffic > Sources of Routing Information

Sources of Routing Information

A router’s routing table can be populated from various sources. As an administrator, you could statically configure a route entry. A route could be learned via a dynamic routing protocol (for example, OSPF or EIGRP), or a router could know how to get to a specific network, because the router is physically attached to that network.
