Dynamic Routing Protocols:
Dynamic routing helps the admin overcome the time-consuming process of configuring and maintaining static routes.
Routing protocols have been used since the early 80s.
Routing algorithms have been in use since 1969.
Some function(s) of Dynamic Routing Protocols:
Dynamically share information between routers.
Automatically update routing table when topology changes.
Determine best path to a destination.

This is a basic rundown of the EIGRP routing protocol Concepts.
EIGRP is an advanced distance-vector routing protocol that relies on features commonly associated with link-state protocols.
Administrative Distance
• Internal 90; Summary 5; External 170 Features of EIGRP
• Classless Routing Protocol (VLSM, CIDR)
• Faster convergence times
• Multiprotocol support:
• Rapid Convergence and Better handling of routing loops – (DUAL)
• Efficient Use of Bandwidth
– Partial, bounded updates: Incremental updates only to the routers that need them.
– Minimal bandwidth consumption: no more that 50% of link’s bandwidth EIGRP packets.
• PDM (Protocol Dependent Module)
• Unequal-cost load balancing
Metrics: Bandwidth, Delay, Reliability, Load

EIGRP Commands
Enabling EIGRP Routing
Router(config)# router eigrp AS number (Must be the same on all routers)
Router(config-router)# network network-address [wildcard mask]
