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}
In an IPv4 environment what information is used by the router to forward data packets from one interface of a router to another?
It uses the MAC address, Media Access Control. Every packet sent from a computer contains its MAC address. The router stores this in its routing table. When it receives a packet with a destiation address of that MAC address, then it forwards it to that computer. This is called NAT, Network Address Translation. It uses the Destination IP address
Which table does a router use to make decisions about the interface through which a data packet is to be sent?
Routing table
What information is required by a router to successfully route packets?
To route a packet, usually an IP packet, a router compares the destination address to its (the router's) routing table. The router can get entries (rows) in its routing table in three different ways: (1) directly connected networks; (2) static routes (the route was configured manually by an administrator); (3) dynamic routes (the router learned available routes from a neighboring router, using a routing protocol such as RIP or OSPF).
Which portion of the network layer address does a router use to forward packets?
In theory, the part that indicates the network. In IP networks, this is the first part of the IP address.The size of the "network" part may vary; therefore, the router checks the address against different rows of its routing table; if, for example, a certain row specifies a network of 10.0.5.0 /24, that means that the first 24 bits must be compared, so the router will compare whether the first 24 bits match.
When a router does not have an interface for the destination network it sends the traffic to where?
If a router has a route in its routing table, it will have a next hop IP address and / or outbound interface. If a router does not have a route in its routing table the packet will be dropped.

Wic address is used by the router to direct a packet between networks?
The router only needs to know the next-hop address; in other words, it sends the data to the next router; this next router then takes its own decision.Each router maintains a routing table, with information about where to send IP packets. The information is stored on a per-network basis. When the router receives an IP packet, it consults the routing table, to see what is the next-hop address, and through which interface it must send the packet.The router only needs to know the next-hop address; in other words, it sends the data to the next router; this next router then takes its own decision.Each router maintains a routing table, with information about where to send IP packets.

What is the similarities and differences between the windows routing table and the router routing table?
That depends entirely on what Operating System the router is running
When will a router select the indicated path as the best match?
After checking with its Routing Table (table creation depends on Routing Protocol).
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.
When forwarding a route which route will router select?
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.
