To enable the automatic selection of a route distinguisher on a VPRN site
Purpose
Since a route distinguisher (RD) must be unique on each PE in the network, you can allocate either a RD that you manually select or an NE-selected route distinguisher for each service. When you configure an auto-RD on a VPRN site, a Type-1 RD is automatically allocated by the NE based on the community range that you configure.
Steps
| 1  | Before you configure a site for auto-RD selection, you must: 
 | 
| 2  | Choose Manage→Service→Services from the NFM-P main menu. The Manage Services form opens. | 
| 3  | Choose a VPRN and click Properties. The VPRN Service (Edit) form opens. | 
| 4  | On the navigation tree, right-click on VPRN Service and choose Create VPRN Site, or right-click on a site and choose Properties. The VPRN Site (Create|Edit) form opens. | 
| 5  | Click on the Routing tab, then on the General tab. | 
| 6  | Set the Route Distinguisher Type parameter to Type 1. | 
| 7  | In the Type 1 panel, set the Auto Route Distinguisher parameter to true. The Operational RD is displayed after you apply the changes to the site and to the service. | 
| 8  | Save the changes and close the forms. End of steps |
