International Travel Agency (ITA) maintains a complex OSPF environment. Your manager asks you to optimize OSPF routing. You need to design and configure multiarea OSPF on the key routers connecting Asian regional headquarters to San Jose corporate headquarters and its local sites. | Multiarea OSPF AREA 0 Lo0 24 Fa0 0 24 Fa0 0 2 SanJose3 SanJosel Lo5 30 Lo0 24 ISP1 to Aukland AREA 1 Singapore 24 24 24 24 Lo1 24 Lo2 24 Lo3 24 30 30 Objective In this lab you configure multiarea OSPF operation interarea summarization external route summarization and default routing. Scenario International Travel Agency ITA maintains a complex OSPF environment. Your manager asks you to optimize OSPF routing. You need to design and configure multiarea OSPF on the key routers connecting Asian regional headquarters to San Jose corporate headquarters and its local sites. Step 1 Build and configure the network according to the diagram but do not configure a routing protocol yet. Note This lab requires the use of subnet 0. You can ignore the ISP1 cloud for now. Configure each router with the loopback address indicated in the diagram. Be sure to configure SanJosel with additional loopbacks Lo0 Lo1 Lo2 Lo3 . These loopback interfaces simulate the serial links to local San Jose sites Westasman Baypointe Vista and Eastasman. Use ping to test connectivity between all interfaces. Each router should be able to ping its link partner. 1 - 9 Semester 5 Advanced Routing - Lab Copyright 2001 Cisco Systems Inc. Step 2 Configure multiarea OSPF. On SanJosel configure FastEthernet 0 0 as a member of Area 0 and all other interfaces as members of Area 1 by using the following commands SanJose1 config router ospf 1 SanJose1 config-router network area 0 SanJose1 config-router network area 1 On SanJose3 configure E0 and Lo0 as members of Area 0 but configure Serial 0 0 as part of Area 51 SanJose3 config router ospf 1 SanJose3 config-router network area 0 SanJose3 config-router network area 51 SanJose3 config-router network .
