For those working with enterprise IT departments, it helps to be able to speak the language of IP connectivity. IP is to data transfer as a dial tone is to a wireline telephone. Data-related conversations with those in enterprise IT departments can sound like they are in a foreign language. This session introduces a number of concepts that might likely arise in such conversations, with a focus on understanding different options for how enterprises might achieve IP communication between different sites. It discusses how the options differ and provides examples of when different options make sense. The session gives special focus to the popular Layer 3 IP-VPN scenario.
Learning Objectives
After completing this course, the student will be able to: • Sketch a layered view of a large enterprise network • Sketch how IP networks are interconnected within a large company • State the role of MPLS in interconnecting networks • List enterprise options for connectivity • Compare and contrast L1, L2 and L3 VPN connectivity solutions • Describe the role of MPLS • Show end-to-end route propagation and traffic flow with Layer 3 VPNs
Intended Audience
This course is intended for anyone seeking a basic overview of Enterprise IP network connectivity.
