The most common IGP in the Internet. RIP uses hop count as a routing metric. Each 'interface' on the router must be configured with a unique 'IP address' and 'subnet mask'. Route that is explicitly configured and entered into the routing table.
Static routes take precedence over routes chosen by dynamic routing protocols.
Useful for controlling security and reducing traffic. The higher the number, the lower the trustworthiness rating. A 'static route' allows manual configuration of the routing table. No dynamic changes to this table entry will occur as long as the path is active. A static route may reflect some special knowledge of the networking situation known to the network administrator.
