What is a Network? – Exclusive Definitions

Before starting Cisco Internetworking, the network introduction is important for the networking student to be aware of “what a network is” and “what network is importance themselves”. So, first of all, what is a network? In simple words, It is a collection of interconnected devices (such as computers, printers, etc.) in such a way that they… Read more

Default Gateway Limitations: Impact on Connectivity and Performance

Hosts at the access layer of a hierarchical network take advantage of the alternate default gateways. If a gateway (router interface) fails, the hosts configured with that gateway are cut off from outside networks. A method is needed to provide alternate default gateways in switched networks where two or more routers are connected to the… Read more

Diagram illustrating ping and traceroute for verifying inter-VLAN routing between Host1 (VLAN 100) and Host2 (VLAN 200) via a router with fa0/0 interface.

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… Read more

Router Switching Mastery: Unlock Efficient Packet Delivery (Updated 2025)

The router is a device that receives a packet from the source on any interface and forwards it to its destination on another interface. This is possible with the router switching function, which encapsulates packets in the data link frame type for the outgoing data link. Before going further, learn the key networking terms for… Read more

Master SVI and VLAN Addressing Issues (Updated 2025)

Each VLAN in the network requires a unique IP subnet because two devices in the same VLAN with different subnet addresses cannot communicate. This is a common problem during VLAN configuration, and we can solve it by identifying the incorrect IP address configuration and changing the address to the correct one. For example, if you… Read more
