Introduction This blog post provides example M-VPN configuration using out-of-band mapping of C-multicast groups to core M-LSP tunnels signaled via M-LDP. A reader is assumed to have solid knowledge of M-VPNs and understanding of M-LDP. For people unfamiliar with M-LDP, the following blog post provides some introductory reading: The long road to M-LSPs. The terminology used in this article follows the common convention of using the "P-" prefix for provider specific objects (e.g. multicas routes... Read More

Overview The purpose of this blog post is to give you a brief overview of M-LSPs, the motivation behind this technology and demonstrate some practical examples. We start with Multicast VPNs and then give an overview of the M-LSP implementations based on M-LDP and RSVP-TE extensions. The practical example is based on the recently added RSVP-TE signaling for establishing P2MP LSPs. All demostrations coud be replicated using the widely available Dynamips hardware emulator. The reader is assumed to... Read More

Abstract: Inter-AS Multicast VPN solution introduces some challenges in cases where peering systems implement BGP-free core. This post illustrates a known solution to this problem, implemented in Cisco IOS software. The solution involves the use of special MP-BGP and PIM extensions. The reader is assumed to have understanding of basic Cisco's mVPN implementation, PIM-protocol and Multi-Protocol BGP extensions. Abbreviations used mVPN – Multicast VPN MSDP – Multicast Source Discovery Protocol PE... Read More
