First, routing is the process a router performs when making forwarding decisions for each packet arriving at the gateway interface. To forward a packet to a destination network, the router requires a route to that network. If a route to a destination network does not exist on the router, the packet will be forwarded to the default gateway. Now, the destination network can be a number of routers or hops away from the default gateway. If the router has an entry for the network in its routing table, it would only indicate the next-hop router to which the packet is to be forwarded to and not the exact route to the final router. To sum it up, the routing process uses a routing table to map the destination address to the next hop and then forwards the packet to the next-hop address.

What is packet forwarding?
Packet forwarding in simple terms is the forwarding of packets from one node to another from networking point of view. For example, a router or a switch. These networking devices make routing devices with the help of their routing tables and then select an outgoing interface. After that they make some changes in the packet header and push (forward) the packet to the selected interface. In case you don't know the meaning of packet. Packer is the smallest unit of size in networking. Different networks has different packet size. For example, in ATM Networks the packet size is of 53 Bytes.
A device that operates at the network layer and can select the best route for a packet to travel over dissimilar networks is called a?
A router.
Which configuration file makes the changes persist across reboots to disable packet forwarding?
Network Configuration and Management is the configuration file that makes the changes persist across reboots to disable packet forwarding.
Can a packet be forwarded without a route?
No packet can be forwarded without a route. Whether the packet is originating in a host or being forwarded by an intermediary device, the device must have a route to identify where to forward the packet.
What portion of the IP packet does a router use to make forwarding decisions?
buffer
A sentence with select?
Let him select a route for you and then suggest an alternate route.
Why is layer three addressing hierarchical?
Layer 3 addressing is hierarchical because it allows the division of networks into subnets. For example, one route entry can refer to a large general network and another can refer to a subnet of that same network. When forwarding a packet, the router will select the most specific route that it knows. However, if a specific subnet is not in the routing table but the larger network that holds the subnet is known, then the router will send it to the larger network, trusting that another router will find the subnet.
Which basic process is used to select the best path for forwarding data?
hz
Why do networking specialists say Switch where you can route where you must?
Yes, the main reason is switch is an inteligent device for routing IP Packet. It substitute conventional hub which is not smart because it broadcast IP packet to all its port. This impact to network performance because IP packet flooding network. While switch have internal routing table that can help switch to forwarding to a exact port where the destination host is connected to its switch port.
When the destination network is not listed in the routing table of a cisco router what two possible actions the router might take?
The router discards the packet.The router forwards the packet out the interface indicated by the default route entry.
Which route will be preferred for this packet?
through the Fa0/1 interface
