What is Dynamic Routing Algorithms (Updated 2025)

By

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… Read more

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

By

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

What is a Routing Table -Explained

By

Routing tables are the backbone of IP networking, guiding routers in forwarding data packets to their intended destinations efficiently. For CCNA and CCNP students, mastering routing tables is essential, as they form a core component of Cisco certification exams and real-world network administration. A routing table contains critical information about network paths, including directly connected

What is Administrative Distance – Explain

By

In network environments, routers often receive multiple routes to the same destination from different sources, such as routing protocols (e.g., OSPF, EIGRP, RIP), static routes, or directly connected networks. To select the most trustworthy route, Cisco routers use Administrative Distance (AD), a critical concept in the Cisco Certified Network Associate (CCNA) curriculum. This article explains AD’s

What is Network Load Balancing

By

Routers use administrative distance (AD) to prioritize routes learned from different routing protocols when multiple paths to a destination exist. AD is a value assigned to each routing protocol, with lower values indicating higher preference (e.g., EIGRP AD is 90, OSPF AD is 110). If multiple paths exist within the same protocol (same AD), the

Mastering Router Path Selection: Best Path Determination (Updated 2025)

By

Understanding how routers select the best path for packet forwarding is a cornerstone of networking and a key topic for CCNA and CCNP certification exams. Routers use their routing tables to determine the optimal path based on metrics like administrative distance and protocol-specific values. This article dives into the mechanics of path selection, including directly

How to Verify Interface Settings

By

As a network engineer, ensuring that Cisco router interface settings are correctly configured is critical for maintaining network performance, security, and reliability. Verifying these settings involves checking interface settings status, IP configurations, duplex settings, and other parameters to ensure they align with the network design. This article provides a step-by-step guide to verifying Cisco router
