Configures an IPv6 neighbor discovery interface policy with router advertisement on a Layer 3 interface. This procedure enables the interface for auto configuration using the GUI.

Before you begin

  • The tenant, VRF, BD are created.

  • The L3Out is created under External Routed Networks.

Note

The steps here show how to associate an IPv6 neighbor discovery interface policy with a Layer 3 interface. The specific example shows how to configure using the non-VPC interface.

Procedure

  1. In the Navigation pane, navigate to the appropriate external routed network under the appropriate Tenant.

  2. Under L3Outs , expand > Logical Node Profiles > Logical Node Profile_name > Logical Interface Profiles .

  3. Double-click the appropriate Logical Interface Profile , and in the Work pane, click Policy > Routed Interfaces .

    Note

    If you do not have a Logical Interface Profile created, you can create a profile here.

  4. In the Routed Interface dialog box, perform the following actions:

    1. In the ND RA Prefix field, check the check box to enable ND RA prefix for the interface.

      When enabled, the routed interface is available for auto configuration.

      Also, the ND RA Prefix Policy field is displayed.

    2. In the ND RA Prefix Policy field, from the drop-down list, choose the appropriate policy.
    3. Choose other values on the screen as desired. Click Submit .
    Note

    When you configure using a VPC interface, you must enable the ND RA prefix for both side A and side B as both are members in the VPC configuration . In the Work Pane, in the Logical Interface Profile screen, click the SVI tab. Under Properties , check the check boxes to enable the ND RA Prefix for both Side A and Side B. Choose the identical ND RA Prefix Policy for Side A and Side B.
