What is a switch vs a router?
This guide will help you understand the subtle differences between a network switch vs a router.
Can a core switch be used as a main router
Yes, a Layer 3 core switch can perform routing functions, but it is optimized for high-speed internal traffic rather than complex WAN routing.Core Switch OverviewA core switch is a high-capacity, high-performance Layer 3 switch that serves as the backbone of an enterprise network, aggregating traffic from distribution switches and ensuring ultra-low latency and maximum throughput across the LAN . It is designed to handle massive internal traffic efficiently, often supporting advanced features like VLAN routing, IP routing between subnets, and dynamic routing protocols such as OSPF and BGP .Routing CapabilitiesLayer 3 core switches can route IP traffic between VLANs and subnets, effectively performing many functions of a router within a local network . They can use routing protocols like EIGRP, OSPF, and BGP to determine optimal paths for internal traffic and can act as a gateway for WAN connections in some configurations . This makes them suitable for internal network routing and high-speed packet forwarding.Differences from RoutersWhile core switches can route traffic, routers are specialized for connecting different networks, particularly between LANs and WANs, and for handling complex tasks such as NAT, firewalling, VPNs, and traffic shaping . Core switches rely on hardware-based ASICs for wire-speed switching, making them faster for internal traffic, whereas routers use CPU-based processing for more sophisticated routing and security functions .Practical Use CasesCollapsed Core Architecture: In smaller or medium-sized networks, a high-performance core switch can combine the roles of core and distribution layers, reducing the need for separate routers .Large Enterprises: Core switches handle internal routing and aggregation, while dedicated routers manage external WAN connections and advanced security .Simplified Networks: For networks with fewer devices or less complex routing needs, a Layer 3 core switch may suffice as the primary routing device .ConclusionA Layer 3 core switch can be used as a router for internal network traffic, providing high-speed routing between VLANs and subnets. However, for external WAN connectivity, advanced security, or complex routing policies, a dedicated router is still recommended. The choice depends on network size, complexity, and performance requirements .

Difference between a Core Switch and Router
A Core switch has layer 3 capabilities and therefore does routing of packets like Routers within VLANs in a campus LAN. The routing capability of core switches is hardware base (best) while
Internet routing via core switch instead of routers?
This service is essentially provided to us as a single CAT5 cable from a Cisco router that handles the failover to VDSL (public IP failover too). We stick this straight into a VLAN on our core switch (Aruba

How to Use a Router as a Switch: A Step-by-Step Guide
If you have an old Wi-Fi router, you can add it to your existing network and use it as a switch or a Wi-Fi extender. You''ll just need to disable DHCP, NAT, and the firewall on the old router,
Why does a core switch need to be behind a router? : r/ccna
I noticed in most topologies there is a L3 switch at the distribution layer and the core layer. why would it need to run to a router after if the switch has routing capabilities? Also why would it even need
Difference between a core switch and ''normal'' switch?

Is a core switch the same as a router?
The core switch performs as a router and bridges the devices. Usually, people are confused about buying a core switch and a router. Why need a router when you have a core switch
Understanding Core Switch: What It Is and How to Choose the Right
In the event of a core switch failure, a backup router can seamlessly assume its functions, minimizing disruptions until the primary switch is restored. By taking these considerations into
Differences Between the Core Switch and Normal Switch | FiberMall
A core switch is not a type of switch, but a switch placed at the core layer (the backbone of the network). Generally, large-scale enterprise networks and Internet cafes need to purchase core
What Is a Core Switch in Networking?
Unlike access switches, which connect directly to end-user devices, the core switch focuses on aggregating and routing traffic between other switches, minimizing latency and
Routing on firewall or core switches? : r/networking
In my research I''m getting mixed suggestions - Some say that core switches are for routing, when others say that core switches have to be as fast as possible and have minimal tasks dedicated to them.
