Routers and Layer 3 Switching

In the OSI model, we discovered that Switches have a place with Layer 2 while Routers have a place with Layer 3.Switches are comprehended to be forward traffic dependent on MAC address while Routers play out the sending dependent on IP address. In any case, Layer 3 Switch is another term which will in general make organizing novices confused. first Question that comes into mind – What is Layer 3 Switch about and how is it not quite the same as Router?

A Layer 3 switch is both a Switch and a Router. We can consider it a switch with numerous Ethernet ports and has an exchanging usefulness. It switches parcels by checking both their IP addresses and their MAC addresses. Layer 3 switches consequently isolates ports into virtual LANs (VLANs) and play out the steering between them notwithstanding supporting directing conventions, for example, RIP, OSPF and EIGRP. Another name for Layer 3 Switch is "Multilayer Switch".So how about we abridge, some key contrast between Layer 3 Switch and Router –

Cost—Layer 3 switches are considerably more financially savvy than switches for conveying fast between VLAN directing. Superior switches are normally considerably more costly than Layer 3 switches.

Port thickness—Layer 3 switches, have a lot higher port check while Routers have a lower port thickness than Layer 3 Switches.

Adaptability—Layer 3 switches permit you to blend and match Layer 2 and Layer 3 exchanging, which means you can design a Layer 3 change to work as a typical Layer 2 switch, or empower Layer 3 exchanging as required.

WAN advancements support – Layer 3 Switch is constrained to use over LAN condition where Inter VLAN directing can be performed, anyway with regards to taking a shot at WAN and edge innovations Layer 3 Switch lingers behind. Switch is the leader in such situation where WAN innovations, for example, Frame Relay or ATM should be cultivated.

Equipment/Software basic leadership – The key distinction between Layer 3 switches and switches lies in the equipment innovation used to help desk technician presenting sending decision.in defense of Layer 3 Switch particular ASICs are utilized for sending choice while if there should be an occurrence of Routers for the most part it's the product rationale which it employments.
