Multicast VPN services are supported on LN2600 and MX devices only.

To create a L3VPN Service definition upon which to base a MVPN service order, in the Network Services > Connectivity view pane, select Service Design > Manage Service Definitions > New > L3VPN Service Definition.

You can associate more than one customer IPv4 pool with each customer. However, each customer pool must have its own set of IPv4 addresses which must not overlap with those of any other pool belonging to the same customer. You can allocate addresses from customer pools across multiple Layer 3 VPNs for a particular customer.
