Difference between Router and Layer-3 Switch
Routers are the connecting devices in networking. it is used to choose the smallest path for a packet to attain its destination. Its main objective is to attach varied networks at the same time and it works in the network layer.
Layer-3 Switches were formed as a technology to boost on the performance of routers utilized in massive native space networks (LANs) like company intranets. The key distinction between Layer-3 switches and routers lies within the hardware technology accustomed build the unit. The hardware within a Layer-3 switch merges that of ancient switches and routers, exchange a number of a router’s software package logic with hardware to supply higher performance in some things. Layer-3 switches typically value but ancient routers. Designed to be used among native networks, a Layer-3 switch can usually not possess the WAN ports and wide space network options a conventional router can perpetually have.
Difference between Router and Layer-3 Switch:
|S.NO||Router||Layer 3 Switch|
|1.||The functionality of router is to connect various networks simultaneously.||The main functionality of layer 3 switch is to connect various devices simultaneously.|
|2.||It supports MPLS and VPN services.||It does not support MPLS and VPN services.|
|3.||It’s throughput is lower than layer-3 switch.||While it provides high throughput.|
|4.||In this, switching capacity is lower than layer-3 switch.||While it has higher switching capacity.|
|5.||It is expensive.||It is inexpensive.|
|6.||It has lower port density.||While it has higher port density than router.|
|7.||Router supports edge technologies such as NAT, Tunneling, Firewall etc.||While it does not support edge technologies.|
|8.||In router, size of routing table is bigger than layer-3 switch routing table for multiple route entries.||While it’s routing table is smaller than router.|
|9.||In router, forwarding is performed by software.||While in this, forwarding is performed by specialized ASICs.|
