Multicast in BGP/MPLS VPNs is described in RFC 6513. Rosen-model with GRE uses a combination of PIM and GRE encapsulations for control-plane and data-plane, respectively. The Customer-multicast (C-Multicast) packets are encapsulated in GRE in the Provider network.
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. In order for IP multicast traffic within a BGP/MPLS IP VPN (Virtual Private Network) to travel from one VPN site to another, special protocols and procedures must be implemented by the VPN Service Provider. These protocols and procedures are specified in this document. MPLS infrastructure. As such, the demand for delivering multicast service across a BGP-MPLS infrastructure in a scalable and reliable way is also increasing. RFC 4364 describes protocols and procedures for building unicast BGP-MPLS VPNs. However, there is no framework specified in the RFC for provisioning multicast VPN (MVPN) services. Up to This document describes the BGP encodings and procedures for exchanging the information elements required by Multicast in MPLS/BGP IP VPNs, as specified in RFC 6513. [STANDARDS-TRACK] For the definition of Status , see RFC 2026 .
Example for Configuring Multicast on a BGP/MPLS IP VPN network. Networking Requirements. As shown in Figure 7-18, users in vpna site2 want to receive multicast data
The Multicast in a VPN I section on contains the VPN configuration required for the provider multicast domain using PIM Any Source Multicast (ASM) with auto-discovery based on PIM or BGP auto-discovery (A/D), PIM used for the customer multicast signaling and PIM Source Specific Multicast (SSM) used for the S-PMSI creation. Request PDF | On Jan 1, 2012, E. Rosen and others published Multicast in MPLS/BGP IP VPNs | Find, read and cite all the research you need on ResearchGate However, to support multicast traceroute over an MPLS/BGP IP VPN according to the techniques described in this disclosure, the PE routers are configured to forward a multicast traceroute request Extranet Multicast in BGP/IP MPLS VPNs Abstract. Previous RFCs specify the procedures necessary to allow IP multicast traffic to travel from one site to another within a BGP/MPLS IP VPN (Virtual Private Network). However, it is sometimes desirable to allow multicast traffic whose source is in one VPN to be received by systems that are in
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.
Aug 10, 2005 · Multicast for MPLS VPNs (MVPN) is configured on top of the VPN configuration. The MPLS VPN network needs to be carefully designed, to observe all recommendations for MPLS VPN networks first. The service provider core must be configured for native multicast service. Example for Configuring Multicast on a BGP/MPLS IP VPN network. Networking Requirements. As shown in Figure 7-18, users in vpna site2 want to receive multicast data ISSN: 2070-1721 Juniper Networks February 2012 Multicast in MPLS/BGP IP VPNs Abstract In order for IP multicast traffic within a BGP/MPLS IP VPN (Virtual Private Network) to travel from one VPN site to another, special protocols and procedures must be implemented by the VPN Service Provider. These protocols and procedures are specified in this document. Also, SAFI 129 has been assigned to "Multicast for BGP/MPLS IP Virtual Private Networks (VPNs)". This document defines a new BGP optional transitive attribute, called "PMSI_TUNNEL". IANA has assigned the codepoint 22 in the "BGP Path Attributes" registry to the PMSI_TUNNEL attribute. 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.
