The video introduces you to Cisco MPLS multicast VPN. We will first go through some theories behind the technology to give you a big picture of configuration steps that will be involved and familiarize you with essential terminologies. The configuration begins at global multicast, of which we will use Source-Specific Multicast (SSM), and followed by Default-MDT and Data-MDT configuration. During configuration, we will provide tips and point out anything that you might need to pay attention to. We will be testing using both Dense and Sparse modes at the client sites. Wireshark packet capture will be performed throughout this lab to help you place the theories into practice, and understand the structure of the multicast packets.
