Interior Gateway Protocols
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Interior Gateway Protocols (IGPs) are a family of network protocols used for exchanging routing information within an autonomous system (AS). They facilitate efficient routing within a single organization or network, ensuring that routers can share topology information to determine optimal paths for data transmission. Common IGPs include OSPF (Open Shortest Path First), EIGRP (Enhanced Interior Gateway Routing Protocol), and RIP (Routing Information Protocol). These protocols are fundamental to the operation of most enterprise and large-scale networks, offering reliable and scalable internal routing solutions.
Key Features

- Various protocols like OSPF, EIGRP, RIP with different features
- Efficient convergence and loop prevention mechanisms
- Scalable for various network sizes from small to large enterprise networks
- Typically operating over IP or other link-layer protocols
- Ability to prioritize routes based on metrics such as cost, bandwidth, or delay
Pros
- Enables efficient and dynamic internal routing
- Supports rapid convergence upon topology changes
- Widely adopted and supported across networking hardware
- Offers various protocol options tailored to network needs
- Facilitates scalable network design
Cons
- Some protocols like RIP have limited scalability due to hop count constraints
