Static and Connected Routes

Static and connected routes are two types of routes that can be used to configure routing in a network.

A connected route is a route that is automatically created when a network interface is configured with an IP address. The route is added to the routing table of the local device, and it indicates that the network is directly connected to that device. For example, if a device is configured with an IP address of 192.168.1.1/24 on interface GigabitEthernet0/1, a connected route for the network 192.168.1.0/24 is automatically added to the routing table.

A static route, on the other hand, is a manually configured route that is added to the routing table by an administrator. A static route specifies the path that packets should take to reach a particular network or host. Static routes are typically used when there is only one path to a destination network or when a particular path is preferred over others.

Here are some differences between static and connected routes:

Configuration: Connected routes are automatically created when an interface is configured with an IP address, whereas static routes must be manually configured by an administrator.

Flexibility: Static routes provide more flexibility in terms of specifying the path that packets should take to reach a particular network or host, whereas connected routes are limited to the physical connections that exist on the local device.

Administrative distance: Static routes typically have a higher administrative distance than connected routes, which means that they are less preferred by the routing table. This can be changed by manually adjusting the administrative distance for the static route. Reliability: Connected routes are generally considered to be more reliable than static routes because they are dynamically updated when a network changes, whereas static routes must be manually updated.
