The network layer or layer 3 is where you would expect to find routers or possibly layer 3 switches. The network layer is the point where different networks can converge. Routing tables held on layer 3 devices are the path out of the network. If you look at your ipconfig information with the /all switch you will see an address given for default gateway. This will point to the router that is aware of all other networks or sub networks you have access to. In the home this is usually the inside or private address of your DSL or cable modem.
I understand some bridges operate at layer 3 as well.
At layer 3 Ethernet frames are formed into packets in preparation for routing between networks or sub networks.
Because the OSI layer is as implied open there are many examples of software and hardware that can operate at the network layer but router would be the best answer most of the time.
What else can I help you with?
4 basic function of datalink layer?
error control and recovery flow control ppp(point to point protocol transfering from physical layer to network entities
A non routable protocol does not operate in which layer of the OSI model?
Network Layer
Connectivity devices such as hubs and repeaters operate at which layer?
Hubs and repeaters operate at the Physical Layer of the OSI Model. The Physical Layer is the first layer of the OSI Model.
Which layer of the hierarchical design model provides a means of connecting devices to the network and controlling which devices are allowed to communicate on the network?
distribution
Which particular layer of OSI model is not required if two devices communicate at the same network?
In this situation Network Layer may not be required. Data Link Layer can handle communication process. If two devices are communicating from different networks then Network Layer a is must. In this situation Data Link Layer is not enough for completing the communication process as it lacks Routing ability which is the primary function of Network Layer.
What layer of OSI model is multipurpose devices on?
If devices are within the same network then they operate at the second layer.
What devices operate only at the Physical layer of the OSI model?
All network devices have some component that operates at layer 1. Only hubs and repeaters operate entirely at layer 1.
What devices operate at the session layer of OSI model?
Gateway network device
Devices found in each OSI model?
1. Repeaters (Operate at the OSI Physical Layer).2. Bridges (Operate at the OSI Data Link Layer).3. Routers {and Brouters} (Operate at the OSI Network Layer).
What is the name of layer in which rarp operates?
datalink layer

What is the highest layer of the OSI model used by router?
Router works in Network Layer of OSI model
CDP operates at which layer?
