The video demonstrates different ways of using Route Target (RT) to build advance Cisco MPLS VPN topologies. We will spend time to gain a better understanding of the role of Route Target, and re-enforce the concept of Route Target import, and export, which is needed for our subsequent labs. These will be delivered through two example topologies of hub-and-spoke and extranet MPLS VPN. This method of exchanging routes between VRFs is also known as route leaking.
