30. 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
