Implementing Cisco MPLS

From the technology basics to advanced VPN configuration.

Course Description

The 5 day course will enable learners to gather information from the technology basics to advanced VPN configuration. The focus of the course is on VPN technology issues of MPLS from the Service Providers perspective and how to configure some of those features and functions in an existing routed environment.
