What osi layer does a router reside in?
All layers - but to the greatest extent, the distinctive work done by the router - specifically, routing packets - corresponds to layer 3.
If data link layer detect error why do you think we need transport layer?
because in the data link layer two routers communitate directly via a physical channel , whereas at the transport layer this physical channel is replaced by the entire subnet. In the data link layer ,it is not necessary for a router to specify which router it wants to talk to each outgoing line uniquely specifies a panicular router . In the transport layer explicit addressing of destinations is required.
Router is a layer 3 or 4 device if your ans is layer 3 then while applying an extended access list on router interface how specifying port no is aloud as it comes under layer 4 protocols?
A router is a layer 3 device.In general, a Layer-3 switch (routing switch) is primarily a switch (a Layer-2 device) that has been enhanced or taught some routing (Layer 3) capabilities. A router is a Layer-3 device that simply do routing only. In the case of a switching router, it is primarily a router that may use switching technology (high-speed ASICs) for speed and performance (as well as also supporting Layer-2 bridging functions). As illustration, here are some examples Layer-2 switches Cisco: Catalyst 2950, 2960 series Layer-3 switches or routing switches Cisco: Catalyst 3550, 3560, 3750, 4500, 6500 series Juniper: EX series Routers (with some bridging and/or security features) or switching routers Cisco: 1800, 1900, 2600, 2800, 2900, 3700, 3800, 3900, 7200, 7600, ASR 1000 series Juniper: MX series, J series, M series
Which portion of the packet does a router use to forward the packet to the destination?
The Destination Address (Layer 2 or Layer 3)
Amplifier work in which layer in osi layer?
Layer 1 - the physical layer
What osi layer does a router reside in?
All layers - but to the greatest extent, the distinctive work done by the router - specifically, routing packets - corresponds to layer 3.
Can a router work at layer 2?
Yes. A router will de-capsulate an frame to verify it was destined for itself. Frames are layer 2.
What are the three layers that a router must implement to operate?
A router must implement the Physical layer, the Link layer, and the Network layer
Which devices work in the presentation layer?
firewall, router,layer 3 switches and i approve that answer ! NO! In general the firewall is a layer 4 device, it traffics filter incoming and outgoing ports. It uses the function of TCP and UCP. However a Firewall can also be a layer 3 device as in internal firewall in a router. Also a switch is a layer 2 device unless your talking about a Router switch.
What layer does a router lie on?
Assuming you are using the OSI Modem a router sits on Layer 3: Network
What is the highest layer of the OSI model used by router?
Router works in Network Layer of OSI model
Why do you call router as layer three device?
Routers operate in layer 3 because they must use the logical network address to determine which network to route the packet to. Logical addressing is a feature of layer 3, therefore a router is a layer 3 device.
What is the role of router in a distribution layer?
== ==
What layer of OSI model does a router operate?
Router is a Layer 3 (Network Layer)device that checks packet's IP Address at input interface & routes them to interface connected to destination network if available.
What device sends and receives information about the network layer?
Perhaps you mean a router?
Which OSI layer defines the functions of a router?
Network Layer - Does path determination and logical addressing.
What is another term for a layer 3 switch?
router operates on Layer 3 and can be used as a switch
