To configure Anycast PIM on a router

Purpose

This procedure describes how to use the Virtual Anycast Manager to configure anycast PIM on a router. The Virtual Anycast Manager automatically configures many of the supporting requirements for the protocol, which reduces operator configuration errors and assists in troubleshooting activities.

Note: The NFM-P does not automatically delete the supporting requirements for the protocol when you delete an anycast RP member.

You can also manually add peers to an anycast RP by navigating to the Anycast RP tab of the PIM configuration form. Ensure that PIM is enabled on the router. See To configure PIM on a routing instance .

The NFM-P raises an alarm when VRFs from different VPRNs are added to a single anycast RP set. You can only mismatch VRFs using methods that are not associated with the Virtual Anycast Manager; for example, by using the CLI or the PIM configuration form.

Steps
 
1 

Choose Manage→Networking→Virtual Anycast RP from the NFM-P main menu. The Manage Virtual Anycast RP form opens.

2 

Click Create. The Virtual Anycast RP form opens.

3 

Configure the required parameters.

4 

If the Anycast RP Type parameter value is VPRN, choose a VPRN service for the anycast RP.

5 

Click Apply. The Status panel appears. The Status panel is used in Step 9 of this procedure to identify configuration problems.

6 

Click on the Components tab.

7 

Add virtual Anycast RP members to the PIM configuration.

Perform the following steps:

  1. Right-click on the Virtual Anycast RP Members icon and choose Add Anycast RP Member. The Enter Interface Name form opens.

  2. Enter the interface name for the loopback interface. The Auto Created Interface Name parameter value appears, if configured.

  3. Click OK. The Enter Interface Name form closes, and the Select Local Address form opens.

  4. Configure the filter criteria.

  5. Choose the local IP address that is used to communicate with the other RP members in the virtual anycast set and click OK. The new local address entry appears on the Components tab under the Virtual Anycast RP Members icon. The new local address entry also appears under the Static RP icon.

    Note:

    The local address is typically the system address.

    The NFM-P automatically performs the following virtual anycast RP configuration tasks.

    • creates a PIM-enabled loopback interface, if not present, with the RP address

    • adds a local address to the anycast RP peer set

    • updates the peer sets that participate in the anycast RP so that all peer sets contain the same members

    • enables PIM on the interface that contains the local IP address

    • creates a static RP that uses the anycast RP address. Groups must be manually created using the Components tab

  6. Repeat Step 7   1 to 5 for each member in the virtual anycast RP.

8 

Add a static group-to-RP mapping for the anycast configuration.

Perform the following steps:

  1. Right-click on a member in the Static RP list and choose Create Static RP. The Static RP (Create) form opens.

  2. Configure the required parameters.

  3. Save your changes and close the form.

  4. Repeat Step 8   1 to 3 for each static group-to-RP mapping that you want to add to the virtual anycast RP configuration. Each member needs a static RP and at least one static group-to-RP mapping. The mappings typically use the same configuration values for each member in the group.

9 

Verify the status of the anycast RP for PIM configuration.

Perform the following steps:

  1. Click on the General tab. The Status panel displays the status of the anycast RP configuration. The NFM-P updates the status when you add a member to or delete a member from the virtual anycast RP. You can also use the Update Status button to manually update the Status panel.

    The following table lists the status check boxes that identify potential configuration problems.

    Check box

    Description

    Missing Group Range(s) Configurations

    At least one anycast RP member does not have a group range for the anycast RP address.

    Inconsistent Peer Sets

    Peer sets of all the anycast RP members are not equal.

    PIM not enabled on loopback interface(s)

    PIM is not enabled on all loopback interfaces that are configured in the virtual anycast RP.

    Only one peer configured

    Only one peer is configured for anycast RP. The configuration requires two or more peers for correct functionality.

    Loopback interface(s) not properly configured

    At least one anycast RP member does not have a loopback interface configured with the anycast RP address.

    Missing Static RP configuration(s)

    A member of the virtual anycast RP does not have a static RP. Each member requires a static RP.

  2. Save your changes and close the form.
