Multicast over Layer 3 VPNs Overview
The Junos OS provides three ways to configure IP version 4 (IPv4) multicast over Layer 3 virtual private networks (VPNs):
- Multiprotocol BGP-based multicast VPNs: next-generation, defined by a set of sender sites and a set of receiver sites and use BGP as the signaling protocol. We recommend using this method to configure multicast on Layer 3 VPNs because it is a simpler implementation than draft-rosen multicast VPNs.
- Draft-rosen multicast VPNs with service provider tunnels operating in any-source multicast (ASM) mode—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. This information is provided to you in case you already have dual PIM multicast VPNs configured on your network.
- Draft-rosen multicast VPNs with service provider tunnels operating in source-specific multicast (SSM) mode—Described in RFC 4364, BGP/MPLS IP Virtual Private Networks (VPNs) and based on the IETF Internet draft draft-rosen-vpn-mcast-07.txt, Multicast in MPLS/BGP IP VPNs. For more information about these types of draft-rosen multicast VPNs, see the Junos Multicast Protocols Configuration Guide.
The reader should be familiar with Layer 3 VPN operation on Juniper Networks routers, as well as standard PIM configurations. For more information on Protocol Independent Multicast (PIM) and Multicast Source Discovery Protocol (MSDP) and their usage in a Layer 3 VPN, see the Junos Multicast Protocols Configuration Guide. For more information on Layer 3 VPN configuration, see the Junos VPNs Configuration Guide. Both manuals are located at https://www.juniper.net/techpubs/software/index.html.
