Episode 102: Link-State and Hybrid Routing Protocols — OSPF, EIGRP, and BGP

This episode examines link-state and hybrid routing protocols, including Open Shortest Path First (OSPF), Enhanced Interior Gateway Routing Protocol (EIGRP), and Border Gateway Protocol (BGP). Link-state protocols like OSPF calculate paths using metrics such as cost, while hybrid protocols like EIGRP combine distance vector and link-state characteristics. BGP is introduced as the protocol of the Internet, exchanging routing information between autonomous systems. These protocols are critical exam topics because they represent modern routing practices.

The discussion expands with real-world examples, such as enterprises using OSPF for internal networks, EIGRP in Cisco environments, or ISPs deploying BGP to manage Internet routing. Troubleshooting considerations include mismatched area IDs in OSPF, authentication errors in EIGRP, or route flapping in BGP. Understanding these protocols ensures you can answer exam questions and support advanced routing in professional environments.
