Configure a range policy to reserve route targets and route distinguishers.

When you create the associated VPRN service, you must enable the Enable RT/RD Auto Assignment parameter on the General tab. You can only configure this parameter during VPRN service creation. See To create a VPRN service .

When you create the associated hub, spoke, or mesh VPRN site or sites, the NFM-P automatically generates the RT and RD based on the range policy. The NFM-P creates the routing policies and community for the sites, and automatically releases and distributes the policies and community to the NEs. The NFM-P assigns the VRF import and export policies to the VPRN site or sites, with the RT values that you are configuring in this range policy, and assigns the auto-generated RD to the VPRN site.
