Building Blocks for Configuring Multiprotocol BGP-Based Multicast VPNs: Next-Generation

Configuring multiprotocol BGP-based (MBGP) multicast VPNs (MVPNs) (also referred to as next-generation Layer 3 VPN multicast) involves a series of major steps. Each major step can have variations; for example, you can choose to configure different types of provider tunnels. Think of the major steps as building blocks that can be used together in various ways.

To implement multiprotocol BGP-based multicast VPNs, you must perform one or more of the following major steps:

• Creating a Unique Logical Loopback Interface for the Routing Instance
• Configuring Interfaces for Layer 3 VPNs
• Configuring BGP, MPLS, RSVP, and an IGP on the PE and Core Routers
• Creating a Routing Instance for a Multiprotocol BGP-Based Multicast VPN
• Option: Configuring Sender and Receiver Sites
• Option: Specifying Route Targets
• Configuring Provider Tunnels
• Enabling Multicast VPN in BGP
• Configuring Intra-AS Inclusive Point-to-Multipoint TE LSPs
• Configuring Intra-AS Selective Provider Tunnels
• Configuring the Master PIM Instance on the PE Router for BGP-Based Multicast VPNs
• Configuring the Router’s IPv4 Bootstrap Router Priority
