multicast ipv6 mvpn

Usage Scenario

To configure an MVPN ID, run the multicast ipv6 mvpn command. The MVPN ID is the IP address of the originator provider edge (PE) in an MVPN. An MVPN ID can be used as:

• Originator router's IP address field value in auto-discovery (A-D) routes.
• Administrator field value in the VRF Route Import Extended Community attribute in BGP VPNv6 routes,if the multicast ipv6 mvpn command is not run, PEs do not send A-D routes, and BGP VPNv6 routes do not carry the VRF Route Import Extended Community attribute.

Precautions

Configuration guidelines for MVPN IDs are as follows:

• The MVPN ID of the user-end device of an RSVP-TE P2MP tunnel must be equal to an MPLS LSR ID.
• The MVPN ID of an mLDP P2MP tunnel can be a valid unicast address, excluding 0.0.0.x and loopback addresses 127.x.x.x. Using an MPLS LSR ID as an MVPN ID is recommended.
  The MVPN ID of a PE must be unique in an MVPN.
  If MVPN has been enabled using the mvpn command, the undo multicast ipv6 mvpn command cannot be executed. Before using the undo multicast ipv6 mvpn command, run the undo mvpn command to disable MVPN of all VPN instances.
