  • 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 © 2006 Cisco Systems, Inc.
