How do hosts ensure that their packets are directed to the correct network destination?
- They have to keep their own local routing table that contains a route to the loopback interface, a local network route, and a remote default route.
- They always direct their packets to the default gateway, which will be responsible for the packet delivery.
- They search in their own local routing table for a route to the network destination address and pass this information to the default gateway.
- They send a query packet to the default gateway asking for the best route.
Answers Explanation & Hints:
Hosts must maintain their own local routing table to ensure that network layer packets are directed to the correct destination network. This local table typically contains a route to the loopback interface, a route to the network that the host is connected to, and a local default route, which represents the route that packets must take to reach all remote network addresses.
