This Virtual Training Services (VTS) offering on configuring Border Gateway Protocol (BGP) is an educational session that includes lecture by a Cisco subject matter expert and hands-on practice exercises that focus on configuring BGP. It provides you with the knowledge and skills to deploy, operate, and maintain BGP in an Internet Service Provider (ISP) backbone network. You will learn the primary principles of BGP and its use in very large networks. Hands-on labs reinforce the lecture materials to make sure that you have the working skills to affect the networks you support. This session consists of one primary lesson and one of two optional lessons that may be chosen at the time of registration. Duration
- Virtual classroom offering: two days, six hours a day.
Upon completing this course, the learner will be able to meet these overall objectives:
Primary lesson objective:
- Implement BGP into a large-scale hierarchical network using best practices for scalability
Optional lesson objectives:
- Implement BGP scaling techniques to improve BGP convergence in a large-scale hierarchical network
- Control routing policy by influencing the BGP path selection process using route maps, prefix lists, and community strings
- Implement multihoming strategies using multiexit discriminators (MEDs) and local preference
The session outline is as follows:
- Session Introduction
- Implement BGP (Primary Lesson)
- Optional Lessons (select one)
- BGP Scaling Techniques
- Implement BGP Policy Control
The lab outline is as follows:
- Connect to the Lab Equipment
- The purpose of this lab is to gain access to the lab devices for later lab exercises.
- Configure and Verify Basic Interior Border Gateway Protocol (IBGP)
- The purpose of this lab exercise is to introduce you to BGP and full-mesh IBGP routing.
- Configure and Verify Exterior Border Gateway Protocol (EBGP)
- The purpose of this lab exercise is to allow you to practice establishing EBGP peering and verify route advertisement and reachability across the network.
- Scale BGP with Peer Templates and Route Reflectors (if BGP Scaling Techniques is selected)
- The purpose of this lab exercise is to configure route reflectors and observe the effect. You will also compare and contrast update groups to peer groups.
- Configure BGP Route Filtering (if Implementing BGP Policy Control is selected)
- The purpose of this lab exercise is to allow you to practice applying BGP routing filtering using the following options: prefix lists, community filters, and AS-path access lists.
- Configure Multihoming Policy (if Implementing BGP Policy Control is selected)
- The purpose of this lab exercise is to achieve desired traffic flows for inbound and outbound traffic using local preference and MEDs.
- This session is intended for network professionals, including designers, implementers, and support staff involved with design and deployment of large-scale networks for large enterprises or high-end ISP networks that use BGP in their backbone network for Inter-AS routing.
- This VTS supports a maximum of 12 students in a single session.
The following are the prerequisites for this session:
- Experience using the Cisco IOS® Software command-line interface (CLI)
- Proficiency in routing fundamentals and IP addressing
- Proficiency in implementing and troubleshooting an Interior Gateway Protocol (preferably Intermediate System-to-Intermediate System [IS-IS] or Open Shortest Path First [OSPF]) in a large-scale hierarchical network
- CCNP® or the equivalent networking knowledge and experience
