SMOAD's SD-WAN router works at **Layer 3** of the OSI model.
Layer 3 is the network layer, which is responsible for routing packets between different networks. The router uses a routing table to determine the best path for each packet based on its destination IP address.
The SMOAD SD-WAN router also includes a number of other features, such as:
Firewall: The router can be used to create a firewall to protect the network from unauthorized access.
VPN: The router can be used to create a VPN to allow users to securely access the network from remote locations.
Load balancing: The router can be used to load balance traffic across multiple WAN connections.
Quality of service (QoS): The router can be used to prioritize traffic for different applications.
The SMOAD SD-WAN router is a powerful tool that can be used to improve the performance, reliability, and security of an organization's WAN.
Here is a diagram of the OSI model:

∙ 12y agoA router operates in the network layer, which deals with the logical addressing of nodes - it is the third layer of the OSI reference model, and the second layer of the TCP/IP model. The router examines the header of a network layer protocol (such as the internet Protocol, IP for short) to determine where the packet needs to be sent next in order for it to reach its destination in a most efficient way.
Routers strip off the lower layer (data link layer) meta-data of a received frame and repackage the packet back into a frame featuring the physical address (MAC) of the router as the source, and the physical address of the next node as the destination - the network layer addresses remain unchanged, unless the router also performs network address translation (NAT). A router is needed in order for a packet to be able to leave the local subnet/broadcast domain (whereas a bridge or a layer two switch is sufficient for forwarding frames between adjacent LAN segments/collision domains.

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
