Adding and Editing VRRP Configuration

Before you begin

You can add a new VRRP configuration or edit an existing configuration to match changing network requirement.

Procedure

  1. Click Add to create a new VRRP configuration.

    Click Edit to modify or override the attributes of a existing VRRP configuration. If necessary, existing VRRP configurations can be selected and permanently removed by clicking Delete.

  2. If you are creating a new VRRP configuration, assign a Virtual Router ID from 1 - 255.

    In addition to functioning as numerical identifier, the ID identifies the virtual router for which a packet is reporting status.

  3. Define the following VRRP General parameters:

    Description

    In addition to an ID assignment, a virtual router configuration can be assigned a textual description (up to 64 characters) to further distinguish it from others with a similar configuration.

    Priority

    Use the spinner control to set a VRRP priority setting from 1 - 254. The controller or service platform uses the defined setting as criteria in selection of a virtual router master. The higher the value, the greater the likelihood of this virtual router ID being selected as the master.

    Virtual IP Addresses

    Provide up to eight IP addresses representing the Ethernet switches, routers, or security appliances defined as virtual router resources.

    Advertisement Interval Unit

    Select either seconds, milliseconds or centiseconds as the unit used to define VRRP advertisements. After an option is selected, the spinner control becomes enabled for that Advertisement Interval option. The default interval unit is seconds.

    If you are changing the VRRP group version from 2 to 3, the advertisement interval must be in centiseconds. Use VRRP group version 2 when the advertisement interval is either in seconds or milliseconds.

    Advertisement Interval

    After selecting an Advertisement Interval Unit , use the spinner control to set the interval the VRRP master sends out advertisements on each of its configured VLANs. The default setting is 1 second.

    Preempt

    Select this option to ensure a high priority backup router is available to preempt a lower priority backup router resource. The default setting is enabled. When selected, the Preempt Delay option becomes enabled to set the actual delay interval for pre-emption. This setting determines if a node with a higher priority can take over all the Virtual IPs from the nodes with a lower priority.

    Preempt Delay

    If the Preempt option is selected, use the spinner control to set the delay interval (in seconds) for preemption.

    Interface

    Select this value to enable or disable VRRP operation and define the VLAN (1 - 4,094) interface where VRRP will be running. These are the interfaces monitored to detect a link failure.
  4. Refer to the Protocol Extension field to define the following:

    Sync Group

    Select the option to assign a VRRP sync group to this VRRP ID‘s group of virtual IP addresses. This triggers VRRP fail over if an advertisement is not received from the virtual masters that are part of this VRRP sync group. This setting is disabled by default.

    Network Monitoring: Local Interface

    Select wwan1, pppoe1, and VLAN ID(s) as needed to extend VRRP monitoring to these local access point interfaces. Once selected, these interfaces can be assigned an increasing or decreasing level or priority for virtual routing in the VRRP group.

    Network Monitoring: Critical Resource

    Assign the priority level for the selected local interfaces. Backup virtual routers can increase or decrease their priority in case the critical resources connected to the master router fail, and then transition to the master state themselves. Additionally, the master virtual router can lower its priority if the critical resources connected to it fails, so the backup can transition to the master state. This value can only be set on the backup or master router resource, not both. Options include None, increment-priority and decrement priority.

    Network Monitoring: Delta Priority

    Use this setting to decrement the configured priority (by the set value) when the monitored interface is down. When critical resource monitoring is enabled, the value is incremented by the setting defined.
  5. Click OK to save your changes.

    Click Reset to revert to the last saved configuration.
