  • Introduction to Gateway Redundancy Protocols

    Gateway redundancy protocols provide high availability and fault tolerance for network gateways by allowing multiple routers to share a virtual IP address. If the active gateway fails, another router in the group takes over, ensuring seamless connectivity for clients. The three main gateway redundancy protocols are: 1. Hot Standby Router Protocol (HSRP) Overview Basic HSRP

  • OSPF Path Manipulation

    OSPF prefers the lowest cost path to determine the best route. While OSPF doesn’t use administrative distance directly for path control like other protocols (e.g., EIGRP or BGP), there are several effective methods to manipulate OSPF routes. 1. OSPF Cost Manipulation (Recommended Method) The most common method to influence OSPF path selection is by adjusting

  • OSPF Neighborship Process and Troubleshooting

    Establishing OSPF neighbor relationships is a critical step before routers can exchange routing information. Understanding the process and troubleshooting steps ensures a stable OSPF network. 1. OSPF Neighborship Process OSPF routers must go through specific steps to establish and maintain adjacency. The process involves 7 states: OSPF Neighbor States State Description Down No Hello packets

  • OSPF Backbone Area and Multi-Area Design

    In OSPF, areas are essential for scalability and efficient routing. The OSPF network is divided into logical segments called areas, with special rules for the Backbone Area (Area 0) and Multi-Area design. 1. OSPF Backbone Area (Area 0) The Backbone Area (Area 0) is the central area in an OSPF network and is crucial for

  • OSPF Path Calculation Process

    OSPF (Open Shortest Path First) calculates the best path to each destination using the Dijkstra’s Algorithm (also known as the Shortest Path First (SPF) algorithm). The process involves multiple steps to ensure accurate and loop-free routing. Step 1: Establish Neighbor Relationships Step 2: Build the Link-State Database (LSDB) Step 3: Run the SPF Algorithm Dijkstra’s

  • OSPF Router ID and DR/BDR Election

    In OSPF (Open Shortest Path First), the Router ID and the Designated Router (DR)/Backup Designated Router (BDR) play key roles in the network’s routing stability and efficiency. 1. OSPF Router ID The Router ID is a unique identifier for each OSPF router. It’s a 32-bit value (similar to an IPv4 address) that is selected based

  • Introduction to OSPF (Open Shortest Path First)

    OSPF (Open Shortest Path First) is a link-state routing protocol used to efficiently route IP packets within large and complex networks. It’s widely used in enterprise environments due to its scalability, fast convergence, and flexibility. Key Features of OSPF ✅ Link-State Protocol → Builds a complete map (topology) of the network.✅ Fast Convergence → Detects

  • Static Routing Concepts

    Static Routing is a manual method of defining routes in a router’s routing table. Unlike dynamic routing protocols, static routes don’t change unless manually updated by the network administrator. Key Features of Static Routing ✅ Manually Configured → Requires manual input of destination network, subnet mask, and next-hop IP.✅ Fixed Paths → Ideal for simple

  • IP Routing explained

    IP Routing is the process of forwarding data packets from one network to another using IP addresses. It determines the best path for data to travel across interconnected networks, ensuring information reaches its intended destination efficiently. Key Concepts in IP Routing How IP Routing Works Types of Routing Example of a Routing Table Destination Network
