How does a router send packets?

When a router receives a packet, the router checks its routing table to determine if the destination address is for a system on one of it’s attached networks or if the message must be forwarded through another router. It then sends the message to the next system in the path to the destination.

Do routers receive packets?

A router receives packets from each interface via a network interface. Received packets have all link protocol headers removed. Most packets are forwarded based on the packet’s IP destination address, along with routing information held within the router in a routing table.

What is the difference between packets and routers?

Packets are created at Layer 3 of the network and allow information to be exchanged between different LANs, typically via routers. A router interconnects small networks (LANs) together allowing for information exchange on a much larger scale using IP addresses for packet forwarding instead of MAC addresses.

What happens when packets enter router?

The router receives the packet and removes the network layer header. After removing the header, it looks at the destination IP address in the packet. After finding out the best match, it forwards the packet through that interface to that network. The same procedure is repeated until the packet reaches its destination.

What are the two jobs that routers do?

A router, then, has two separate but related jobs:

• The router ensures that information doesn’t go where it’s not needed.
• The router makes sure (hopefully)that information does make it to the intended destination.

Do Routers send packets or frames?

Yes. A router must strip off the layer-2 frame in order to get to the layer-3 packet. The router then routes the packet to the next interface toward the destination, based on the layer-3 destination address.

What are the two kinds of Ethernet packets?

There are several types of Ethernet frames:

• Ethernet II frame, or Ethernet Version 2, or DIX frame is the most common type in use today, as it is often used directly by the Internet Protocol.
• Novell raw IEEE 802.3 non-standard variation frame.
• IEEE 802.2 Logical Link Control (LLC) frame.
