Configuring Draft-Rosen Multicast VPNs

Draft-rosen multicast VPN with provider tunnels operating in any-source multicast (ASM) mode is a legacy feature. We recommend that you implement multiprotocol BGP-based multicast VPNs for multicast VPNs. Use this section to maintain your already existing draft-rosen multicast VPNs with provider tunnels operating in ASM mode. To implement this type of draft-rosen IPv4 multicast for a Layer 3 VPN, configure the following:

• Configuring BGP, MPLS, RSVP, and an IGP on the PE and Core Routers
• Creating a Unique Logical Loopback Interface for the Routing Instance
• Configuring the Master PIM Instance on the PE Router
• Configuring PIM and the VPN Group Address in a Routing Instance
• Option: Configuring PIM Sparse Mode Graceful Restart for a Layer 3 VPN
• Option: Configuring Multicast Distribution Trees for Data
• Option: Configuring MSDP Within a Layer 3 VPN
