Configuring Multicast VPN
The following tasks configure multicast VPN (MVPN):
• Enabling a VPN for Multicast Routing, page MCC-41 (required)
• “Configuring BGP to Advertise VRF Routes for Multicast VPN from PE to PE” (required)
See the module “Implementing BGP on Cisco IOS XR Software” in Cisco IOS XR Routing
Configuration Guide.
• Configuring an MDT Address Family Session in BGP as a PE-to- PE Protocol (optional for PIM-SM
MDT groups; required for PIM-SSM MDT groups)
See the “Configuring an MDT Address Family Session in BGP” section inCisco IOS XR Routing
Configuration Guide.
• Configuring a provider-edge-to-customer-edge protocol (optional)
See the “Configuring BGP as a PE-CE Protocol,” “Configuring OSPF as a PE-to-CE Protocol,” and
“Configuring EIGRP as a PE-to CE Protocol” sections in Cisco
IOS XR Routing Configuration
Guide.
• Specifying the PIM VRF Instance, page MCC-44 (optional)
• Specifying the IGMP VRF Instance, page MCC-46 (optional)
• Configuring the MDT Source per VRF, page MCC-47 (optional)
For an examples of end-to-end MVPN configuration, see Configuring IPv4 Multicast VPN: Example,
page MCC-69and Configuring IPv6 Multicast VPN on the Cisco XR 12000 Series Router: Example,
page MCC-79.
Prerequisites for Multicast VPN
When configuring MVPN, you must meet the following prerequisites:
• PIM and multicast forwarding must be configured on all interfaces used by multicast traffic. In an
MVPN, 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.
Note PIM and multicast forwarding are enabled in multicast routing configuration mode. No
additional configuration is required in router pim mode to enable the PIM protocol.
• Interfaces in the VPN intended for use in forwarding multicast traffic must be enabled for PIM and
multicast forwarding.
• BGP should already be configured and operational on all routers that are sending or receiving
multicast traffic.
• To enable MVPN, you must include a VPN IPv4 or VPN IPv6 address-family (AFI) in your BGP
configuration. See
Restrictions for Multicast VPN for Multicast Routing, page MCC-41. (See also
the “Enabling BGP Routing” section in Cisco IOS XR Routing Configuration Guide.)
