Every router between subnets is a gateway with the default gateway for any device being where any destination not in the routing table typically outside your subnet is sent.

If not updated, the router forwards the packets to the same interface even though the interface is down. This results in data loss. The static route must be configured on every router for gaining full connectivity between source and destination. As the router does not exchange routing information, it is difficult to select the best path for the router by itself.

The static routing consumes very few resources. The Static routing is good for the networks that are not changed very often. The main disadvantage of static routing is that this is impractical for large networks. In case of any topology changes, the administrator has to manually update all the routers. The administrative distance can be a number ranging from 0 to and it defines the trust worthiness of a route.

All packets not matching a specific match in the routing table will be matched using the default route and forwarded to Now at the packet level what happens is that when a device attached to the network needs to communicate with another device it will first check whether the other device is on the same network or another network by comparing the IP address of the other device with subnet mask assigned to itself.

If it is on another network the it will create a packet with the source IP of itself and destination of of the other device. However the layer 2 frame will have the source of address of the device itself while the destination address will be the layer 2 address of the gateway.
