Scenario: You are a network administrator for an Internet service provider. After successfully establishing an EBGP session between your ISP and the International Travel Agency (ITA), users within the ITA network still can’t access the Internet. Step 1 Cable the lab as shown in the diagram. Load the configuration files into your routers. Step 2 Begin by viewing the routing table on router ISP1B. ISP1B#show ip route Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area * - candidate default, U - per-user static route, o - ODR 2-2 Semester 8 Internetwork Troubleshooting v1.0 - Lab 14.3.3.1 Copyright 2001, Cisco Systems, Inc.

What is your plan of action to allow Internet access for the ITA autonomous system? Step 4 Implement action plan and issue show ip route, show ip bgp and show ip bgp summary. Step 5 Document your work with summary of problem, troubleshooting methods and resolution. . Inc.
