Configuring Multicast Vpn; Prerequisites For Multicast Vpn - Cisco XR12000 Series Configuration Manual

Implementing Multicast Routing on Cisco IOS XR Software

Configuring Multicast VPN

•
• "Configuring BGP to Advertise VRF Routes for Multicast VPN from PE to PE" (required)
• Configuring an MDT Address Family Session in BGP as a PE-to- PE Protocol (optional for PIM-SM
• Configuring a provider-edge-to-customer-edge protocol (optional)
•

Prerequisites for Multicast VPN

• PIM and multicast forwarding must be configured on all interfaces used by multicast traffic. In an MVPN,
• Interfaces in the VPN intended for use in forwarding multicast traffic must be enabled for PIM and
• BGP should already be configured and operational on all routers that are sending or receiving multicast
• To enable MVPN, you must include a VPN IPv4 or VPN IPv6 address-family (AFI) in your BGP

you must enable PIM and multicast forwarding for the following interfaces:
◦ Physical interface on a provider edge (PE) router that is connected to the backbone.
◦ Interface used for BGP peering source address.
◦ Any interfaces configured as PIM rendezvous points.
