29 © 2006 Cisco Systems, Inc. All rights reserved.Cisco PublicITE 1 Chapter 6 29 Design and Configure a Network Using EIGRP  EIGRP issues and limitations

30 © 2006 Cisco Systems, Inc. All rights reserved.Cisco PublicITE 1 Chapter 6 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
