Episode 88: Routers — Path Decision Makers
Routers are the decision-makers of the network, directing traffic between different IP networks and ensuring that data finds the most efficient path to its destination. In this episode, we focus on router functionality, including how routing tables are built, how static and dynamic routes are applied, and how the router uses metrics and administrative distance to prioritize paths. You'll also learn how routers separate broadcast domains and operate across subnets to create scalable, segmented networks.
We explore how routers interact with interfaces, how default gateways operate, and how routing protocols like OSPF and RIP enable routers to adapt to changing topologies. This episode gives you the operational knowledge needed to understand both small office routers and enterprise-grade edge routers. Routers are also a major focus of exam questions, making this a core topic to master for your certification journey.
