Access, Distribution, and Core Layers Explained
If the network includes a separate core layer, the distribution layer connects the access layer to the core. The following image shows how the distribution switches operate when a separate

If the network includes a separate core layer, the distribution layer connects the access layer to the core. The following image shows how the distribution switches operate when a separate
Access switches provide connectivity to end-user devices within a LAN, while core switches route data between different networks. Understanding the differences and similarities between access switches
The core switch is the backbone of your network. It''s the most important piece of equipment because it connects all your other switches and routes traffic between them. The access
The access switch is the network switch that connects the access layer with the subnets. The subnets are integrated with access devices like routers, IP devices, control, and monitoring panels, etc.
Similarly, the distribution switch lies in the distribution layer, and it links upwards to the layer core switch and downwards to the access switch. It is also called an aggregation switch which functions as a
This model divides the network into three functional layers: the Access Layer, the Distribution Layer, and the Core Layer. The Access Layer sits at the edge, using switches to connect
Similarly, the distribution switch lies in the distribution layer, and it links upwards to the layer core switch and downwards to the access switch. It is also called an
The main difference is their role: an access switch connects end-user devices (like PCs) to the network, whereas a core switch connects multiple distribution switches together to move large
The access switches connect directly to these collapsed core switches. The collapsed core switch performs inter-VLAN routing, enforces ACL security policies, and provides high-speed
You would presumably connect your access-layer switches with redundant links to your core/distro layer. As such OSPF/EIGRP should see 2 equal cost paths to the core.
Each layer is served by specialized switches, with the access switch connecting end-user devices, the distribution switch aggregating traffic and enforcing policies, and the core switch acting as the high
