Draft Rosen multicast VPNs—Draft Rosen multicast VPNs are described in RFC 4364, BGP/MPLS IP Virtual Private Networks (VPNs) and based on Section Two of the IETF Internet draft draft-rosen-vpn-mcast-06.txt, Multicast in MPLS/BGP VPNs (expired April 2004).
Jan 11, 2019 · All customer multicast traffic (C-Multicast) will be encapsulated in MPLS packers and will traverse the network leveraging point-to-multipoint LSPs. Configuration Steps. The following things need to be configured for NG-MVPN to work: On the P devices: P-to-PE Interfaces with IP addresses and family MPLS. The Multicast VPN—IP Multicast Support for MPLS VPNs feature allows a service provider to configure and support multicast traffic in a Multiprotocol Label Switching (MPLS) Virtual Private Network (VPN) environment. The PE router has a Multicast aware VPN for the CE router, The interface to the CE router is in sparse dense mode, and in the Multicast VPN. The PE router also has the MDT tree configured as well. The Loopbacks are all enable on the MPLS backbone with sparse-dense-mode for BGP. All interface going from PE-P routers are in sparse mode. When we are ruuning Multicast MPLS VPNs , we establish PE-PE PIM Neighbouship per VRF over the MDT Tunnel used for the VRF which is a dynamic always on tunnel. On a per PE basis we will see only PIM Neighbourship with the attached CE and Remote PEs participating the particular VRF for Multicast over the MDT Tunnel. Mar 08, 2010 · The out-of-band approach is well known by Rosen’s MVPN implementation, where M-VPN endpoints are discovered by means of MP-BGP extensions and MDTs are mapped to SP core multicast groups (P-tunnels) by means of manual configuration. Mar 21, 2018 · Multiprotocol BGP is explained in RFC 4760. It defines the extensions to BGP-4 to enable it to carry the routing information for multiple Network Layer protocols (e.g., IPv6, L3VPN). Therefore, we will configure the MP-BGP to distribute customers’ prefixes. The extensions are backward compatible. Cisco Systems' Solution for Multicast in BGP/MPLS IP VPNs .

MP-BGP. MP-BGP is used in a MPLS VPN environment to advertise customer routes, associated labels, and other attributes. MP-BGP is discussed further in the next section, "MPLS Layer-3 VPNs." Multiprotocol extensions for BGP are discussed in RFC 2858. MPLS Layer-3 VPNs. MPLS VPNs can be provisioned over a shared provider backbone.
Understanding Next-Generation MVPN Network Topology. Layer 3 BGP-MPLS virtual private networks (VPNs) are widely deployed in today’s networks worldwide. Multicast applications, such as IPTV, are rapidly gaining popularity as is the number of networks with multiple, media-rich services merging over a shared Multiprotocol Label Switching (MPLS) infrastructure.
Knowledge of Multi-Protocol BGP (MP-BGP) and RFC 4364, BGP/MPLS IP Virtual Private Networks (VPNs), is assumed throughout this example, as well as Protocol Independent Multicast (PIM), RFC 6513, Multicast in MPLS/BGP IP VPNs, and RFC 6514, BGP Encodings and Procedures for Multicast in MPLS/BGP IP VPNs. That’s what we need MP-BGP for. MP-BGP supports IPv4 unicast/multicast, IPv6 unicast/multicast and it has support for VPNv4 routes. To exchange VPNv4 routes, MP-BGP uses a new NLRI (Network Layer Reachability Information) format that has the following attributes: Jun 14, 2011 · MVPN Multicast with Multi-Protocol BGP MPLS VPN on Cisco IOS. Below assumes you have the basic MPLS transport setup. MVPN or multicast vpn is deployed on Cisco gear using Multicast Distribution Trees (MDT). This information is encapsulated in the MPBGP MPLS sessions to be distributed into label switch paths (LSPs) for forwarding. Understanding Next-Generation MVPN Network Topology. Layer 3 BGP-MPLS virtual private networks (VPNs) are widely deployed in today’s networks worldwide. Multicast applications, such as IPTV, are rapidly gaining popularity as is the number of networks with multiple, media-rich services merging over a shared Multiprotocol Label Switching (MPLS) infrastructure. 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.
