Routing protocols define various ways that routers chat among themselves to determine the best routes to each destination.

It includes the following topics -

• Interior and Exterior Routing Protocols
• Dynamic routing protocol and routing protocol functions
• IGP Routing Protocol algorithms metrics and administrative distance
• Distance Vector Routing Protocol features and loop prevention
• Route Poisoning and Counting to infinity problem
• Split Horizon poison reverse and triggered updates
• The Holddown Process and Holddown Timer
• Link State Routing Protocol and building it
• Using Dijkstra SPF
• Convergence with Link State Protocols
