Border Gateway Protocol BGP Training

Duration: 1-2 days

Introduction

Border Gateway Protocol (BGP) is the core routing protocol of the Internet. This one-day tutorial provides an intensive discussion of the BGP architecture and operation, transit autonomous systems, route selection using policy controls and attributes, implementation of customer-to-provider connectivity, considerations related to the scaling of service provider networks, optimization of scalability, and deployment considerations. Upon course completion, you will have solid knowledge of this important member of the family of IP routing protocols.
