Meeting RIP, OSPF, and BGP

Dynamic routing relies on protocols, and three names come up most on the Network+ exam: RIP, OSPF, and BGP. Each learns and shares routes, but they differ in how they work and where they fit. This lesson gives a friendly introduction to all three so you can recognize their roles, strengths, and the situations they were designed for.

First, a key split. An IGP (Interior Gateway Protocol) routes within a single organization or autonomous system. An EGP (Exterior Gateway Protocol) routes between different organizations across the internet. RIP and OSPF are interior protocols; BGP is the exterior protocol that ties the whole internet together. Knowing this divide helps you place each protocol correctly.
