Verifying Inter-VLAN Routing Using Ping and Tracert Commands

Inter-VLAN routing enables communication between devices on different VLANs, a critical concept. Verifying host-to-host connectivity ensures proper configuration and operation of inter-VLAN routing. This article explores the ping and tracert utilities, essential tools for network engineers to test connectivity and troubleshoot issues. When configuring the Inter-VLAN routing, we must verify the host-to-host connectivity and data...

Router-on-Stick Inter-VLAN Routing – Exclusive Explanation

In a previous lesson, legacy inter-VLAN routing requires multiple physical interfaces on the router and the switch. However, in the ‘Router-on-stick’ configuration, only one physical interface is needed on both sides. The Router-on-a-stick allows routing packets to subnets associated with VLANs connected to a router 802.1Q trunk. The Router-on-Stick uses a VLAN trunking configuration and...

Master Legacy Inter-VLAN Routing (Updated 2025)

As we learned, each VLAN usually works on its own subnet. The network switches mainly work at layer 2 of the OSI model, so they do not examine the logical addresses. Therefore, for traffic between VLANs, inter-VLAN routing is required. The Legacy Inter-VLAN routing is the first solution for traffic between different VLANs. It relies...

What is Dynamic Routing Algorithms (Updated 2025)

Dynamic routing is a networking technique that provides optimal data routing. The network administrators and engineers configure a dynamic routing protocol on the network interfaces. The protocol running on the router learns about other routers automatically and also dynamically exchanges routing information with other routers. Dynamic routing protocols perform several activities, including network discovery and...

Master How to configure Static Route – IPv4 and IPv6 (Updated 2025)

We can configure static or dynamic routes after configuring directly connected interfaces. Static routes are manually configured and provide a clear path between two networking devices. However, they must be manually reconfigured if the network topology changes, which is the main disadvantage of static routes. It is more secure and efficient than dynamic routes. It...
