Overview:
Interior routing protocols serve a different purpose than exterior routing protocols. Interior routing protocols discover paths between networks whereas exterior routing protocols route between autonomous systems.
Study Notes:
- Areas introduce heirarchy into network architectures.
- An autonomous system is essentially a grouping of areas
- Interior Routing Protocols discover paths between networks
- RIP
- EIGRP
- OSPF
- Exterior Routing Protocols route between autonomous systems
- BGP
- EGP
- IDRP
