Which portion of the packet does a router use to forward the packet to the destination?
The Destination Address (Layer 2 or Layer 3)
Which packet destination address will R2 forward to R1?
**192.168.142.1
When forwarding a packet which route will the packet 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.

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 part of an ip packet does the router use to make routing decisions?
the network portion of the destination ip address
Which information must a router have in order to perform proper and efficient routing?
Destination network address of an incoming packet
What information is used by routers to forward packets?
The IP address. The router compares the destination IP address of an IP packet with the router's routing table, which says, for example, "everything that starts with 172.16.5 should be sent out through port Serial 2".
What address does the router use to compare to the routing table?
in general the router uses the network address to compare to the routing table. Specifically, on the internet, the Router looks up the destination IP address in the router table to determine where to route the packet.
What part of a packet is used to get to destination?
Destination address
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.
Which portion if the destination IP address is used as a packet is routed through the Internet?
Which portion of the destination IP address is used as a packet is routed through the Internet?
