Prerequisites for MVPNv6

  • 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.

Restrictions for MVPNv6

Point-to-point GRE tunnel as an output interface in a VRF for MVPNv6 is not supported.

Information About MVPNv6

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.

How to Configure MVPNv6
