Configure layer 3 IPv6 multicast functionality in a VRF using the GUI to ENABLE PIM6 protocol and related settings.

This task enableslayer 3 IPv6 multicast routing capabilities within a VRF by configuring PIM6 protocol, interfaces, rendezvous points, and associated policies to support multicast traffic forwarding.

IPv6 multicast configuration is required when you need to enable multicast traffic forwarding in Layer 3 networks using PIM6 protocol within a specific VRF context.

Before you begin

  • The desired VRF, bridge domains, Layer 3 Out interfaces with IPv6 addresses must be configured to enable PIM6. For Layer 3 Out, for IPv6 multicast to work, an IPv6 loopback address is configured for the node in the logical node profile.

  • Basic unicast network must be configured.

Follow these steps to configure Layer 3 IPv6 MULTICAST using the GUI:

Procedure

  1. On the menu bar, navigate to Tenants > Tenant_name > Networking > VRFs > VRF_name > MULTICAST IPv6.

    In the Work pane, a message is displayed as follows: PIM6 is not enabled on this VRF. Would you like to ENABLE PIM6?.

  2. Click YES, ENABLE MULTICAST IPv6.

  3. Configure interfaces:

    1. From the Work pane, click the Interfaces tab.
    2. Expand the Bridge Domains table to display the Create Bridge Domain dialog, and choose the appropriate BD from drop-down list.
    3. Click Select.
    4. Expand the Interfaces table to display the Select an L3 Out dialog box.
    5. Click the L3 Out drop-down arrow to choose an L3 Out.
    6. Click Select.

  4. Configure a rendezvous point (RP).

    1. In the Work pane, click the Rendezvous Points tab, choose Static RP.
    2. Enter the appropriate value in each field.
    3. Click Update.

  5. Configure the pattern policy.

    1. From the Work pane, click the Pattern Policy tab and choose Any Source MULTICAST (ASM).
    2. Enter the appropriate values in each field.

  6. Configure the PIM settings.

    1. Click the PIM Setting tab.
    2. Enter the appropriate value in each field.

  7. When finished, click Submit.

  8. On the menu bar, navigate to Tenants > Tenant_name > Networking > VRFs > VRF_name > MULTICAST IPv6, and perform these actions:

    1. In the Work pane, Interfaces tab, choose the appropriate L3 Out and from the PIM Policy drop-down list, choose the appropriate PIM policy to attach.
    2. Click Submit.

  9. To verify the configuration perform these actions:

    1. In the Work pane, click Interfaces to display the associated Bridge Domains.
    2. In the Navigation pane, navigate to the associated BD with IPv6 MULTICAST.
      In the Work pane, the configured PIM functionality is displayed as configured earlier.
    3. In the Navigation pane, navigate to the associated L3 Out interface.
      In the Work pane, the PIM6 check box is checked.
    4. In the Work pane, navigate to Fabric > Inventory > Pod NodeProtocols > PIM6 and expand PIM.
      Under the appropriate PIM6 protocol that was created earlier, you can view information about he associated Neighbors, PIM Interfaces, Routes, Group Ranges, and RPs. You can verify that all these objects are set up.

IPV6 multicast is successfully configured on the VRF with PIM6 enabled. The configuration includes interfaces, rendezvous points, pattern policies, and PIM settings that ENABLE MULTICAST traffic forwarding in the Layer 3 network.
