Connected and Static Routes

Connected and static routes are two types of routing that can be used to direct network traffic between devices.

A connected route is a route that is automatically created by a router when an interface is configured with an IP address. The router adds the subnet of that interface to its routing table with an administrative distance of 0. Connected routes are useful for directing traffic within a local network segment.

A static route is a manually configured route that tells a router how to reach a destination network. The administrator specifies the destination network and the next hop router to reach that network. Static routes are useful for directing traffic between networks that do not change frequently.

Both connected and static routes have their advantages and disadvantages. Connected routes are easy to configure and maintain, but can quickly become unmanageable in larger networks. Static routes are more flexible and allow for more control over routing decisions, but require manual configuration and can become outdated if network changes occur.

Routing protocols such as OSPF, BGP, and EIGRP can be used to dynamically exchange routing information between routers, allowing them to learn about new networks and adjust their routing tables accordingly.
