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
 

Before you configure a site for auto-RD selection, you must:

  1. Enable BGP on the routing instance of the NE; see Procedure ; To enable BGP on a routing instance

  2. Enable the automatic selection of an RD on the NE and specify the community range. See To enable the automatic selection of an RD on an NE .


Choose Manage→Service→Services from the NFM-P main menu. The Manage Services form opens.


Choose a VPRN and click Properties. The VPRN Service (Edit) form opens.


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.


Click on the Routing tab, then on the General tab.


Set the Route Distinguisher Type parameter to Type 1.


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.


Save the changes and close the forms.
