Purpose, Functions and Concepts ofFirst Hope Redundancy Protocol(FHRP) In a switched network setup, each client device is typically configured with a singular default gateway. This means that even if there’s an alternative path available, client devices are restricted to using only the assigned primary gateway. This limitation becomes apparent during network disruptions, as there’s no …

Understanding Virtual Local Area Network (VLAN) in Networking A local area network(LAN) consists of computers within the same network group or broadcast domain. However, when we discuss virtual LANs, it means the network is divided into different groups based on various criteria such as departments, work patterns, server farms, and so on.    Virtual LANs …

Determine Packet Forwarding Decision of Router The router determines the best route for a packet by maintaining a routing table, which stores information about available routes. This table includes both statically configured and dynamically learned routes. When packets arrive, the router inspects this table to select the best route. Routing Table To check what’s in …

What is Layer 2 Switching Loop? A physical loop or Layer 2 switching loop occurs when there are multiple active connections (links) between two switches in a network. This can lead to a broadcast storm, where data circulates endlessly, causing network chaos. For example, in a network with four interconnected switches, there are two sets …
