The document discusses routing protocols for enterprise networks, comparing flat networks to hierarchical topologies. It covers configuring networks using RIP, a distance vector protocol, and EIGRP, Cisco's proprietary protocol. Key topics include building routing tables, static versus dynamic routing, RIP and EIGRP metrics and operation, and designing networks using EIGRP features like summarization.

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
