MPLS is used to forward packets over the backbone while BGP is used to distribute routes, offering a scalable alternative to fully meshed circuit or tunnel-based IP VPNs. Security and privacy within an MPLS VPN is achieved by limiting the distribution of routing information to members of the VPN.

“Native IP multicast”, MPLS, L2, optical IP multicast sources: Encoder, Transcoder, Groomer, Ad-Splicer, … IP multicast receivers: Transcoder, Groomer, Ad-Splicer, QAM, STB IP == IPv6 (Japan) or IPv4 (RotW rest of the world) No address exhaustion issue (SSM) No/slow move to IPv6 for IPTV in RotW Broadcast IPTV = IP multicast Border Gateway Protocol/ Multiprotocol Label Switching (BGP/MPLS) L3 Virtual rivate Network (VPN) allows a Service Provider (SP) or an Enterprise to provide the service of interconnecting geographically dispersed customer sites. NG mVPN (BGP/MPLS) parte de los mismos protocolos empleados en el servicio unicast MPLS L3 VPN (RFC 2547, RFC 4364 BGP MPLS VPNs) y les añade algunas extensiones necesarias para poder soportar el tráfico multicast. Este modelo conserva la buena escalabilidad y flexibilidad del servicio unicast VPN. Mar 15, 2013 · This video illustrates the signaling of Inclusive Provider Tunnels in BGP Next-Generation Multicast VPNs. The tunneling technology used is P2MP LSPs signaled with RSVP. 120 IPExpert IP Mar 13, 2018 · Note: The combination of VRF, MPLS and MP-BGP ensures that the traffic from one VPN does not leak into the other VPN, while the same private IP address space can be used for the VPN sites. Using MPLS for forwarding packets in the provider’s backbone network brings another benefit in the form of traffic engineering (TE). [RFC6513] to refer to a BGP/MPLS IP VPN that supports multicast. Provider Edge (PE) routers that attach to a particular MVPN exchange customer multicast (C-multicast) routing information with The unicast routing policies and configurations supported by BGP-4 can mostly be applied to multicast. Multiprotocol BGP is also widely deployed in case of MPLS L3 VPN, to exchange VPN labels learned for the routes from the customer sites over the MPLS network, in order to distinguish between different customer sites when the traffic from the

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.

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 .

Sep 12, 2019 · A single receiver in a multicast group or a group of receivers that are flapping frequently and interested in a specific multicast group actrivates multicast VPN (MVPN) BGP dampening. MVPN BGP dampening dampens the type 7 multicast routes (customer-multicast, or “C-multicast,” route join/prune) within the core using BGP signaling.

This Week: Deploying BGP Multicast VPNs, 2nd Edition, assumes the reader has at least some experience with IP/MPLS architectures, including Multiprotocol BGP and IGPs. You are not expected to be an expert in multicast as the basic concepts are revisited in the book, but if you are already familiar with BGP/MPLS IP VPNs, you will find this book Feb 13, 2006 · A guide to using and defining MPLS VPN services Analyze strengths and weaknesses of TDM and Layer 2 WAN services Understand the primary business and technical issues when evaluating IP/MPLS VPN offerings Describe the IP addressing, routing, load balancing, convergence, and services capabilities of the IP VPN Develop enterprise quality of service (QoS) policies and implementation guidelines Analysis of the Security of BGP/MPLS IP Virtual Private Networks (VPNs) M.
