Summary
Enterprise networks are hierarchical
Networks use static and dynamic routing to move information
Dynamic routing protocols are classified as either distance vector or link state
RIP is a distance vector routing protocol
EIGRP is a Cisco proprietary distance vector routing protocol with many advanced features
EIGRP works best if its default features are modified to suit the routing situation
