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:
|
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.
|
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:
|
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:
|
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. End of steps |
