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
