Configuring VRRP for the interface

You can manage and configure VRRP parameters for the routing interface.

To configure the VRRP Interface:

  1. From the Device Manager menu bar, choose IP Routing > VRRP > Interface.
    2. The VRRP dialog box opens with the Interface tab displayed.

The table below describes the fields in the Interface tab.


Field Description
VrId
A number that uniquely identifies a virtual router on a given VRRP router. The virtual router acts as the default router for one or more assigned addresses (1 to 255).
Interface
Interface of the VRRP router.
IpAddr
The assigned IP addresses that a virtual router is responsible for backing up.
VirtualMacAddr
MAC address of the virtual router interface.
State
The state of the virtual router interface:
  • initialize--waiting for a startup event
  • backup--monitoring availability and state of the master router
  • master--functioning as the forwarding router for the virtual router IP address(es)
Control
Whether VRRP is enabled or disabled for the port or VLAN.
Priority
Priority value to be used by this VRRP router. Set a value from 1 to 255, where 255 is reserved for the router that owns the IP addresses associated with the virtual router. The default is 100.
MasterIpAddr
The IP address of the physical interface of the master virtual router that has the responsibility of forwarding packets sent to the virtual IP address(es) associated with the virtual router.
AdvertisementInterval
The time interval (in seconds) between sending advertisement messages. Set from 1 to 255 seconds with a default of 1 second. Only the master router sends advertisements.
VirtualRouterUpTime
The time interval (in hundredths of a second) since the virtual router was initialized.
CriticalIpAddrEnable
Sets the IP interface on the local router to enable or disable the backup.
CriticalIPAddr
An IP interface on the local router configured so that a change in its state would cause a role switch in the virtual router (for example, from master to backup) in case the interface stops responding.
HoldDownTimer
The time interval (in seconds) a router is delayed when changing to master state.
HoldDownState
Status is active when the Hold Down Timer is counting down and preemption will occur; the text box displays dormant when preemption is not pending.
HoldDownTimeRemaining
The seconds remaining before preemption.
OperAction
Use the action list to manually override the delay timer and force preemption:
  • preemption--preempt the timer
  • none--allow the timer to keep working

  1. Click the HoldDownTimer text box, and enter the desired number of seconds for the timer.
    2. The HoldDownState field displays active when the Hold Down Timer is counting down and preemption will occur; the text box displays dormant when preemption is not pending. When the Hold Down Timer is active, the HoldDownTimeRemaining field displays the seconds remaining before preemption.
    Use the Action field to manually override the delay timer and to force preemption. When you click the heading, an arrow appears. Click the text box, and a list opens. Choose preemption to preempt the timer, or choose none to allow the timer to keep working.
  2. Click Apply.
