TAC - PPP
This module presents the basic concepts and terminology of BGP. You learn the basic Cisco IOS Software BGP commands and configure basic BGP settings on a Cisco simulated router network, creating BGP loop-free interdomain routing between autonomous systems (ASs) in three Configuration Labs.
At the end of this tutorial, you will be able to:
- Identify and explain basic BGP concepts, attributes, and terminology.
- Describe how BGP forms peers (neighbors).
- Differentiate between eBGP and iBGP, and how they each enable BGP routing.
- Explain why using loopback interfaces to define a neighbor is common for iBGP but not for eBGP.
- Illustrate the difference between eBGP multihop and eBGP multihop (load balancing).
- Describe the purpose and use of neighbor templates.
- Recognize that route maps are a method used to control and modify routing information.
- Identify and describe the functions of match and set commands.
- Demonstrate the network command and how it controls what networks are originated by a router.
- Design an alternative way of advertising networks with Interior Gateway Protocol (IGP) redistributed into BGP, using the redistribute command.
- Construct static routes as a way of redistributing networks.
- Explain the principles of the BGP decision algorithm.
- List and define how BGP selcts a path.
- External BGP (eBGP)
- iBGP and Synchronization
- Load Balancing and Loopback Interfaces
