Objective

Configure EBGP between the company’s core routers and the two ISP routers, and

configure IBGP with peers to create a network that will provide the International Travel

Agency with a fully meshed, reliable, and efficient core network.

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.)
