The continuing proliferation of traffic across today’s networks demands the deployment of an efficient and robust means of data transmission. Border Gateway Protocol (BGP) addresses this need. BGP is increasingly deployed across many commercial networks to facilitate routing and information exchange. This in depth and up-to-date training course will give you a thorough grounding in this complex routing protocol. Following the completion of this course you will be able to install, configure and maintain BGP with confidence thus ensuring the effective exchange of data across reliable and robust networks.
This course will be of value to all professionals who are responsible for configuring, administering and troubleshooting a BGP network. It will also provide the advanced skills necessary for the future implementation of BGP or the migration to BGP across an autonomous system.
