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 the command used to configue a static route for a router?
ip route {destination prefix} {destination prefix mask} {interface OR forwarding router's IP address}
What router protocol would you select if there is only one network route to a remote network?
telnet
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.
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.
Do you need to restart a router to enable port forwarding?
It strictly depends on the model. Most routers have to be restarted in order to enable port forwarding.
What portion of the IP packet does a router use to make forwarding decisions?
buffer
How do you setup port forwarding on beetel 450tc1 router airtel connection?
yes
Which solution provides the most efficient use of router resources for forwarding traffic?
RIPv2
Why each input port in a high speed router stores a shadow copy of the forwading table?
With the shadow copy, the forwarding decision is made locally, at each input port, without invoking the centralized routing processor. Such decentralized forwarding avoids creating a forwarding processing bottleneck at a single point within the router.
If a router receives a packet that is does not know how to forward what type of route must be configured on the router to prevent the router from dropping it?
