Network topology architectures refer to the overall layout or structure of a computer network. Different network topology architectures have their own characteristics that define how devices are interconnected and how data flows within the network. Below are examples of Network Topology Architectures including 2 tier, 3 tier, Spine-leaf, WAN, Small office/home office (SOHO), and On-premises and cloud. i.… Read More »
Interswitch connectivity involves connecting multiple switches to form a larger network, allowing devices connected to different switches to communicate as if they were on the same switch. This process relies on several key concepts: trunk ports, 802.1Q, and native VLAN. a. Trunk Ports Trunk ports are switch ports configured to carry traffic for multiple VLANs (Virtual Local Area… Read More »
Static routing involves manually configuring routing entries into a router’s routing table. Unlike dynamic routing, which uses algorithms and protocols to determine routes automatically, static routes are fixed and must be updated manually if the network topology changes. Both IPv4 and IPv6 static routing follow similar principles but are applied to different address families. i. Default Route A… Read More »
A router uses a systematic process to determine the best route for forwarding a data packet. This process involves several key factors: longest match, administrative distance, and routing protocol metric. Below is a detailed explanation of each factor and how they contribute to the routing decision: 1. Longest Match The longest match principle means that the router selects… Read More »
Understanding Gateway Load Balancing Protocol (GLBP) Gateway Load Balancing Protocol (GLBP) is a Cisco proprietary solution for redundancy and load balancing in an IP network. GLBP allow automatic selection and simultaneous recovery from first hop router failures. GLBP is designed to overcome some of the limitations of earlier First Hop Redundancy Protocols (FHRPs) such as Hot Standby Router… Read More »
