The MDT (multicast distribution tree) is the solution that utilizes PIM in the core of the network (ASM, bidir, or SSM) and builds multicast trees per VPN. The state information maintained in the core of the network is limited to the information specifically required to maintain the trees.
Multicast VPN: Overview Each Multicast Domain consists of a Default-MDT Each Default-MDT uses a separate Multicast Group inside of Provider’s Network Blue Red Blue Red (*,239.1.1.1) (*,239.1.1.2) Blue Red CE CE CE CE CE CE PE PE PE PE Provider Net Jan 11, 2019 · Next Generation Multicast VPN (NG-mVPN) NG-mVPN is a next-generation multicast distribution technology that is predominantly used in service provider networks and addresses scalability and manageability issues associated with the previous generation of SP Multicast VPN (Draft Rosen). The Multicast VPN Extranet Support feature supports only Protocol Independent Multicast (PIM) sparse mode (PIM-SM) and Source Specific Multicast (SSM) traffic; PIM dense mode (PIM-DM) and bidirectional PIM (bidir-PIM) traffic are not supported. M Series,MX Series,T Series,SRX Series. The Junos OS provides two types of draft-rosen multicast VPNs: o P-tunnel. A multicast tunnel through the network of one or more SPs. P-tunnels are used to transport MVPN multicast data o C-S: A multicast source address, identifying a multicast source located at a VPN customer site. o C-G: A multicast group address used by a VPN customer. o C-flow: A customer multicast flow. set vpn l2tp remote-access client-ip-pool start 192.168.100.240 set vpn l2tp remote-access client-ip-pool stop 192.168.100.249 set vpn l2tp remote-access dns-servers server-1

We will first go through some theories behind the technology to give you a big picture of configuration steps that will be involved and familiarize you with essential terminologies. The configuration begins at global multicast, of which we will use Source-Specific Multicast (SSM), and followed by Default-MDT and Data-MDT configuration
As multicast data is sent from the multicast server to the multicast group (224.0.0.0 through 239.255.255.255), the firewall queries its IGMP state table for that group to determine where to deliver that data. Similarly, when the appliance receives that data at the VPN zone, the appliance queries its IGMP State Table to determine where it The MDT (multicast distribution tree) is the solution that utilizes PIM in the core of the network (ASM, bidir, or SSM) and builds multicast trees per VPN.

An application cannot receive multicast data from a private enterprise server through a VPN connection on a client computer that is running Windows 7, Windows Server 2008, Windows Vista, or Windows Server 2008 R2 IP multicast is a method of sending Internet Protocol (IP) datagrams to a group of interested receivers in a single transmission. It is the IP-specific form of multicast and is used for streaming media and other network applications. Apr 16, 2018 · Note Typically, multicast streams are not sent over the Internet because most network segments on the Internet are not multicast-enabled. When a client tries to connect to a stream or to a multicast stream by using UDP protocol, the Windows Media Format SDK and Windows Media Player try to open the ports in Windows Firewall that are required to To enable multicast across the WAN through a VPN, follow: Step 1: Enable multicast globally. On the Firewall > Multicast page, check the Enable Multicast checkbox, and click the Apply button for each security appliance. A typical multicast on an Ethernet network, using the TCP/IP protocol, consists of two parts: Hardware/Ethernet multicast and IP Multicast. Later on I will talk about Mapping IP Multicast to Ethernet Multicast which is really what happens with multicasting on our Ethernet network using the TCP/IP protocol. Multicast routing is very different than unicast routing. Multicast is a form of broadcast, and like broadcast, it will not normally cross a layer-3 device, e.g. router. To overcome this, you use IGMP and PIM to route multicast. You should also be aware that many tunnels cannot transport multicast. You need a GRE tunnel. – Ron Maupin May 25
