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
VPN labels The idea: Use a label to identify the next-hop at the remote PE. Also called VPN label. The label is distributed by BGP, along with the VPN-IP address. Traffic will carry two labels, the VPN label and the LSP label. The remote PE makes the forwarding decision based on the VPN label. ip multicast-routing ip multicast-routing vrf A ! interface Loopback0 ip address 10.10.5.5 255.255.255.255 ip pim sparse-dense-mode ! interface Ethernet0/0 ip address 10.10.35.5 255.255.255.0 ip pim sparse-mode ! interface Ethernet0/3 ip vrf forwarding A ip address 10.10.57.5 255.255.255.0 ip pim dense-mode ! router ospf 1 mpls ldp autoconfig MVPN enables a service provider to transport his multicast traffic across MPLS packet-based core networks for IP VPN customers and to implement the "ships in the night" approach with MPLSthat is, the coexistence of separate routing constructs. Figure 1. Basic MPLS/BGP VPN Network A Private IP network is architectured around an emerging standard known as RFC 2547 bis or more commonly by BGP/MPLS VPN.Service providers use this approach to combine MPLS for forwarding the data and BGP for controlling the routes in order to construct secure, cost-effective VPNs that are easy to implement.
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.
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 MULTICAST VPNS The networking industry has been looking for the best way to offer Multicast VPN services while leveraging the strength and scalability of the existing unicast L3VPN technology. The result of several years of effort is Multi-Protocol BGP Multicast VPN, often referred to as MBGP MVPN.
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.
