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
