What is a router and what are its purpose?
router networking/roo't*/ A device which forwards packets between networks. The forwarding decision is based on network layer information and routing tables, often constructed by routing protocols.
What three network devices operate at the Data-link layer of the OSI?
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 is diff between layer 3 switch and router?
both are the common inter networking devices(functionally) but the layer 3 switch has the functionality of both switch and router, layer 3 switch are most commonly used in frame relay networks, layer 3 switches are also capable of inter vlan routing
Which OSI layer addressing is required to route packets between two networks?
layer 3
What is the function of routing in the network OSI layer3?
The whole point of the network layer, and layer 3 devices, is to move packets between separate networks. Layer 2 devices on the other hand (switches), only move frames using only the data link layer between hosts in that same network. Without layer 3 devices (routers or gateways), there could be no communication between separate interconnected groups of computers.
In a three-layer hierarchical network design which distribution layer function delineates broadcast domains?
routing between VLANs
What device is used to send data between two networks?
If the message is going between two different networks then it must be routed (this includes different subnets of the same network as well). Routing is done by a router as the device.
Which OSI layer handles framing and routing?
Framing is done at the Data Link layer (Layer 2). Routing is done at the Network layer (Layer 3).
Why are routers typically not interconnected at the distribution layer?
There are network stability issues when routing large amounts of network data traffic if the networks are fully or even partially meshed together
What does ip routing enabled?
Enabling routing on a layer 3 switch.
Where are routing tables stored?
Hi , Routing table is the bulk of IP addresses which is defined with the help of Next Hop IP address and normally routing table is used in compuetr networks so it is stored in the form of database in computer networks or Router which is layer 3 device and contains the routing table in it.

What layer of the OSI model performs routing?
network layer
