1 Case Study 1 EIGRP Cisco Networking Academy Program CCNP 1: Advanced Routing v3.1

2 Instructions Plan, design and implement the complex International Travel Agency EIGRP network shown in the diagram and description below. Implement the design on the lab set of routers. Verify that all configurations are operational and functioning according to the guidelines. 2-4 CCNP 1: Advanced Routing v3.1 CS1 Copyright 2003, Cisco Systems, Inc.

3 Scenario The responsibilities of the network engineer with International Travel Agency include creating and maintaining the San Jose campus network, connectivity to all regional headquarters, and Internet access via one or more service providers. The San Jose campus network must maintain 99.9% availability, while supporting 99% availability to regional headquarters. The network will be based on and must meet the following requirements: 1. The San Jose core routers must run EIGRP. 2. The network has been allocated one Class B license. 3. Use VLSM on all serial interfaces as may be appropriate. 4. This network will have three branches. The regional headquarters in Singapore and Auckland will run EIGRP. The Westasman branch office will run EIGRP. The Vista and Eastasman branch offices will run IGRP. 5. Summarize all routes from each area into the core. Plan for approximately 30 networks in each area with exception of the core, which is exactly as shown in the diagram. 6. Redistribute routing information between EIGRP and the IGRP network. 7. In Westasman, implement EZ IP on the router for users. Copyright 2003, Cisco Systems, Inc. Case Study 1: EIGRP 3-4

4 8. In the IGRP cloud of Vista and Eastasman, configure a DHCP server for a LAN segment. Use an IP helper address so that a workstation on another segment in that area can obtain an IP address from the DHCP server. 9. Configure Internet connectivity through a static route. 10. Document the configuration and any difficulties that were encountered. 11. What were the implementation issues or limitations? 12. List two suggestions for improving this network configuration and design. 4-4 CCNP 1: Advanced Routing v3.1 CS1 Copyright 2003, Cisco Systems, Inc.

5 Case Study 2 OSPF Cisco Networking Academy Program CCNP 1: Advanced Routing v3.1

6 Instructions Plan, design, and implement the complex International Travel Agency OSPF network shown in the diagram and description below. Implement the design on the lab set of routers. Verify that all configurations are operational and functioning according to the guidelines. 2-4 CCNP 1: Advanced Routing v3.1 CS2 Copyright 2003, Cisco Systems, Inc.

7 Scenario The International Travel Agency has decided to change the network routing protocol. The responsibilities of the network engineer include creating, maintaining and implementing changes to the network. The network will be based on and must meet the following requirements: 1. The San Jose core routers must run OSPF and be configured in Area The network has been allocated one Class A license. 3. Use VLSM on all serial interfaces as may be appropriate. 4. This network will have three outer areas. The regional headquarters in Singapore and Auckland in Area 1 will run OSPF normally. The Westasman branch office in Area 2 will be a totally stubby network. The Vista and Eastasman branch offices will be RIP networks. 5. Summarize all routes from each area into the core. Plan for approximately 30 networks in each area in the diagram with the exception of the core, exactly as shown in Area Redistribute routing information between OSPF and the RIP network. 7. In the West Tasman branch office in Area 2, implement EZ IP on the router for users. Copyright 2003, Cisco Systems, Inc. Case Study 2: OSPF 3-4

8 8. In the Vista and East Tasman branch offices RIP cloud, configure a DHCP server on a LAN segment. Use an IP helper address so that a workstation on another subnet in that area can obtain an IP address from the DHCP server. 9. Configure Internet connectivity through a static route. 10. Document the configuration and any difficulties that were encountered. 11. What were the implementation issues or limitations? 12. List two suggestions for improving this network configuration and design. 4-4 CCNP 1: Advanced Routing v3.1 CS2 Copyright 2003, Cisco Systems, Inc.

9 Case Study 3 BGP/OSPF Routing Cisco Networking Academy Program CCNP 1: Advanced Routing v3.1

10 Instructions Plan, design and implement the complex International Travel Agency BGP/OSPF network shown in the diagram and description below. Implement the design on the lab set of routers. Verify that all configurations are operational and functioning according to the guidelines. 2-4 CCNP 1: Advanced Routing v3.1 CS3 Copyright 2003, Cisco Systems, Inc.

11 Scenario The International Travel Agency relies heavily on the Internet for its advertising and sales. Therefore, it has been decided to establish a primary and a backup route to the Internet. Additionally, other network changes have been planned as shown in the diagram above and described below. The responsibilities of the network engineer include creating, maintaining, and implementing changes to the network. The network will be based on and must meet the following requirements: 1. The San Jose core routers must run OSPF and be configured in Area The network has been allocated one Class B license. 3. Use VLSM on all serial interfaces as may be appropriate. 4. This network will have three outer areas. The London branch office in Area 1 will be a totally stubby network. The Capetown branch office in Area 2 will be an NSSA. The third area will be a RIP network. 5. Summarize all routes from each area into the core. Plan for approximately 30 networks in each area in the diagram with the exception of the core, known as Area Redistribute routing information from RIP into OSPF. The RIP network should use default routing to access the rest of the network and Internet. Copyright 2003, Cisco Systems, Inc. Case Study 3: BGP/OSPF Routing 3-4

12 7. In the RIP area, implement EZ IP for users. 8. This International Travel Agency network will be multihomed to ISP1A. The primary link will be a T3 connection. A backup T1 link will also be configured. All outbound and inbound traffic are to use the T3 link. The T1 link should be used only if the T3 link goes down. 9. (Optional) A firewall must be configured on the SanJose3 ASBR. This firewall should allow all traffic originating inside AS 200 to pass freely. No traffic originating from outside AS 200 should be permitted into the network. 10. Document the configuration and any difficulties that were encountered. 11. What were the implementation issues or limitations? 12. List two suggestions for improving this network configuration and design. 4-4 CCNP 1: Advanced Routing v3.1 CS3 Copyright 2003, Cisco Systems, Inc.
