Configuring BGP on Cisco Routers (BGP)

This course provides students with in-depth knowledge of BGP, the routing protocol that is one of the underlying foundations of the Internet and new-world technologies such as Multiprotocol Label Switching (MPLS). This curriculum covers the theory of BGP, configuration of BGP on Cisco IOS routers, detailed troubleshooting information and hands-on exercises that provide students with the skills needed to configure and troubleshoot BGP networks in customer environments. Different service solutions in the curriculum cover BGP network design issues and usage rules for various BGP features preparing students to design and implement efficient, optimal and trouble free BGP networks.

The latest version of this instructor led training course contains a virtual lab model that allows each student to have their own pod and access the lab 24 hours a day, 7 days a week for 90 days from the start of the course.

Following completion of this course, you 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 route selection process in a network scenario where 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.
• Implement the correct BGP configuration to successfully connect the customer network to the Internet in a network scenario where you must support multiple connections
• Enable the provider network to behave as a transit autonomous system in a typical service provider network with multiple BGP connections to other autonomous systems
• Identify common BGP scaling issues and enable route reflection and confederations as possible solutions to these issues in a typical service provider network with multiple BGP connections to other autonomous systems
