Scenario The International Travel Agency relies heavily on the Internet for advertisement, sales, and communication within the company and with their customers throughout the world. They have, therefore, decided to contract with two ISPs. They are connected as shown in the figure. The company requires its network to be readily available and reliable at all times. (The loopback addresses on the ISP1A and ISP2 routers represent other customers. The loopback addresses on the San Jose routers represent networks to regional headquarters and local branch offices.) 2 - 2 Semester 5: Advanced Routing v2.0 - Lab 9.8.1 Copyright  2001, Cisco Systems, Inc. Implementation Requirements • Configure EBGP between the International Travel Agency core routers and ISP1A and ISP2. • Configure IBGP between the International Travel Agency core routers. • Only the internal 192.168.0.0 network should be advertised to ISP1A and ISP2 (distributed access lists). • SanJose1 should be able to communicate with ISP2 through SanJose3, and SanJose2 should be able to communicate with ISP1A through SanJose3 (next-hop-self). • SanJose1 will use ISP1A as its primary ISP through its direct link, and SanJose2 will use ISP2 as its primary ISP. • If either direct link of SanJose1 or SanJose2 fails for any reason, all traffic should automatically be routed through SanJose3 to either ISP1A or ISP2. • The International Travel Agency’s AS number 100 should be prevented from being advertised beyond the ISP1A and ISP2 routers to the outside world and to their other customer networks (loopback addresses). Implementation Completion Tests • A successful ping to every network (interface) from every router. • The show command verifies that routing tables contain the routes specified by the requirements. . 1 - 2 Semester 5: Advanced Routing v2.0 - Lab 9.8.1 Copyright  2001, Cisco Systems, Inc. 9.8.1 BGP Challenge Lab SanJose1 SanJose3 SanJose2 Lo0 11.0.0.1/8 ISP2A ISP1A Lo0. 192.168.112.5 /30 Objective Configure EBGP between the company’s core routers and the two ISP routers, and configure IBGP with peers to create a network that
