Your Sw 3 is not L3 switch but L2 which does not support routing; replace sw3 with L3 one (c3560 or c3650 that is more square box in PT) or a router. Then enable ip routing, make ports as trunk ports, add vlans to be sam...

In this session, Our focus will be to learn about the existing and new High Availability features present on the Catalyst 9k Switches. We will also categorize features based on access and Distribution layer in
At work I was asked to connect the following two different subnet using cisco 2960x switch. all the switches we have are cisco catalyst 2960x running version 15.2.
If all your devices (those with static IPs and those with dynamic IPs) are within the same subnet (192.168.0.0/24), the switch will simply handle the traffic at Layer 2, and no routing is necessary.
Detailed post about the network edge. Contains high and low level designs, considerations for Dual ISPs, and BGP guidance.
Learn Layer 2 and Layer 3 switches in 2026. Covers features, performance, design patterns (campus, branch, data center), and how to choose for your network.
I often hear it''s advantageous to utilize layer 3 at the access layer devices to avoid having broadcasts spanning the network and not having to deal with huge STP topologies. But what exactly does this
The first topic linked below describes how to configure Layer 3 interfaces. The latter topic link describes how to use Neighbor Discovery Protocol (NDP) to provision IPv6 hosts and view the IPv6 addresses
Frequently Asked Questions Can a Layer 3 Switch Replace a Router for Inter-Vlan Internet Access? Yes, if it supports routing and NAT. You''d create SVI interfaces for VLANs, run IP
Multihoming allows the configuration of secondary-network interfaces for K8s pods. OVN-Kubernetes secondary-network has three configurable topologies: layer 3, layer 2, or localnet. A layer 3 topology
This article outlines a basic example of how layer 3 routing functionality on MS series switches could be implemented. Before proceeding, please refer to the Layer 3 Switch Overview for general information
