Configuring BGP of Cisco Routers (BGP)

Course Objectives:

After completion of this course, students will be able to…

• Describe how to configure, monitor, and troubleshoot basic BGP to enable interdomain routing in a network scenario with multiple domains.
• Describe how to use BGP policy controls to influence the BGP route selection process in a network scenario in which you must support connections to multiple ISPs.
• Describe how to use BGP attributes to influence the route selection process in a network scenario where you must support multiple connections.
• Describe how to successfully connect the customer network to the Internet in a network scenario in which multiple connections must be implemented.
• Describe how to configure the service provider network to behave as a transit AS in a typical implementation with multiple BGP connections to other autonomous systems.
• Enable route reflection as possible solution to BGP scaling issues in a typical service provider network with multiple BGP connections to other autonomous systems.
• Describe the available BGP tools and features to optimize the scalability of the BGP routing protoco in a typical BGP network.
