The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This module describes how to configure IPv6 Multicast Virtual Private Network (MVPNv6) to enable service providers to use their existing IPv4 backbone to provide multicast-enabled private IPv6 networks to their customers.
Your software release may not support all the features documented in this module. For the latest caveats and feature information, see Bug Search Tool and the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the feature information table.

BGP must be configured and operational on all devices sending or receiving multicast traffic.
BGP extended communities must be enabled to support the use of Multicast Distribution Trees (MDTs) in the network. Use the neighbor send-community both or neighbor send-community extended command to enable BGP extended communities.
VPN routing and forwarding (MVRF) instances to be used for MVPNv6 must be configured on the PE devices.
Point-to-point GRE tunnel as an output interface in a VRF for MVPNv6 is not supported.
Information About MVPNv6
To provide Layer 3 multicast services to customers with multiple distributed sites, service providers need a secure and scalable mechanism to transmit multicast traffic across the service-provider network. IPv4 Multicast VPN (MVPN) provides such services for IPv4 multicast traffic over a shared service provider backbone.
IPv6 Multicast Virtual Private Network (MVPNv6) provides the same services for IPv6 traffic, enabling service providers to provide multicast-enabled private IPv6 networks to their customers using their existing IPv4 back bone. The IPv4 and IPv6 VPN traffic is carried over the same tunnels simultaneously.
