To create and configure a VRRP instance

Purpose

Before you create a VRRP instance on an interface, ensure that the L3 service or network interface is configured with a primary IP address. The backup IP address that is configured in To create a VR must belong to the same subnet as the primary IP address of the owner VRRP instance created in this procedure. The NFM-P automatically configures a backup address using the IP address of the VR. A search of interface IDs in Step 5 of this procedure displays the interface IDs that are eligible for the creation of a VRRP instance for the VR.

Interfaces on VPRN sites must be associated with an SNMP community. See To configure an SNMP community on a VPRN site for more information about configuring an SNMP community for a VPRN site.

You can configure up to a total of four VRRP instances (IPv4 plus IPv6) on one IP interface. The maximum number of mixed IPv4 and IPv6 VRRP instances on an NE is 1024.

Note: The 7705 SAR does not support the configuration of a passive VRRP instance or the configuration of VRRP on a network interface.

Steps
 
1 

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

2 

Choose a VR and click Properties. The Virtual Router (Edit) form opens.

3 

Click on the Components tab.

4 

Right-click on VR Instances and choose Create VRRP Instance. The VRRP Instance (Create) form opens.

If the Backup Address parameter value that you specified in Step 3 of To create a VR is an IPv6 address, then the contextual menu item is Create VRRP IPv6 Instance, and the VRRP IPv6 Instance (Create) form opens.

5 

Assign an interface to the instance.

Perform the following steps:

  1. Click Select in the Interface panel. The Select Interface - VRRP Instance or Select Interface - VRRP IPv6 Instance form opens, depending on whether you are creating an IPv4 or IPv6 VRRP instance respectively.

  2. Choose an interface, and click OK. The Select Interface - VRRP Instance (or Select Interface - VRRP IPv6 Instance) form closes and the VRRP Instance (Create) or VRRP IPv6 Instance (Create) form reappears with the interface information displayed.

6 

Configure the required parameters in the VRRP Instance Information panel.

If your set the Owner parameter to true, then you cannot configure the Administrative State and Base Priority parameters, and cannot associate a policy with this VRRP instance. Go to Step 8 .

7 

Assign a VRRP policy to the instance, if required.

The same VRRP policy can be applied to both IPv4 VRRP instances and IPv6 VRRP instances.

  1. Click Select in the Policy panel. The Select VRRP Policy form opens.

  2. Choose a VRRP policy and click OK. The Select VRRP Policy form closes and the VRRP Instance (Create) form reappears with the VRRP policy information displayed.

8 

Click on the Behavior tab and configure the required parameters.

9 

If you require bidirectional forwarding detection for the VRRP instance.

Then, perform the following tasks:

  1. Select the Enable BFD Interface check box. The BFD Interface tab appears.

  2. Click on the BFD Interface tab.

  3. Click Select beside the Service Name parameter, and choose a service from the Select Service - BFD Interface form.

  4. Click Select beside the Interface Name parameter, and choose an interface from the Select Interface - BFD Interface form.

  5. Configure the Destination Address parameter.

10 

Click on the Authentication tab, and configure the required parameters.

11 

Click on the Backup Addresses tab.

12 

Click Create. The Backup Address (Create) form opens.

13 

Perform one of the following to configure backup addresses:

  1. Enter an IPv4 address (for an IPv4 VR) or IPv6 address (for an IPv6 VR) manually in the IP Address field in the Backup Address section.

  2. Select the IP address from a list.

    Perform the following steps:

    1. Click Choose IP Address adjacent to the IP Address field. The Select IP Address form opens.

    2. Choose an IP address and click OK.

      The Select IP Address form closes and the IP Address parameter is populated with your selection.

    3. Click Add Link Local Address. The Admin Link Local Address defined for the network L3 access interface appears in the IP Address field.

      If you need to add the Link Local Address as a backup address, then the Admin Link Local Address must be configured and the Admin Link Local Address Preferred parameter must be enabled for the network L3 access interface that you are using. See To create an L3 network interface on a routing instance for more information.

14 

Save your changes and close the form.

15 

Click OK. The Virtual Router (Edit) form reappears with the VRRP instances displayed in the VR instances tree.
