Modifying VRRP parameters for an interface

Before you begin

  • You must enable VRRP on a brouter port or VLAN.

About this task

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

Procedure

  1. In the navigation pane, expand the following folders: Configuration > IP.
  2. Click VRRP.
  3. Click the Interface tab.
  4. Double-click the HoldDownTimer field, and enter the number of seconds for the timer.

    The HoldDownState field displays active when the hold-down timer is counting down and preemption occurs. The field displays dormant when preemption is not pending. When the hold-down timer is active, the HoldDownTimeRemaining field displays the seconds remaining before preemption.

  5. In the Action check box, select an option.
  6. Click Apply.

Interface Field Descriptions

Use the data in the following table to use the Interface tab.

Name

Description

IfIndex

Specifies the index value that uniquely identifies the interface to which this entry applies.

VrId

Specifies a number that uniquely identifies a virtual router on a Virtual Router Redundancy Protocol (VRRP) router. The virtual router acts as the default router for one or more assigned addresses.

IpAddr

Specifies the assigned IP addresses for which a virtual router is responsible to provide backup.

VirtualMacAddr

Specifies the MAC address of the virtual router interface.

State

Specifies 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, the primary VRRP router, for the virtual router IP addresses.

Control

Specifies whether VRRP is enabled or disabled for the port (or VLAN). The default is enabled.

Priority

Specifies the priority value used by this VRRP router. The value 255 is reserved for the router that owns the IP addresses associated with the virtual router. The default is 100.

AdvertisementInterval

Specifies the time interval, in seconds, between sending advertisement messages. The default is 1 second. Only the primary VRRP router sends advertisements. The default is 1.

MasterIpAddr

Specifies the IP address of the physical interface of the primary virtual router that forwards packets sent to the virtual IP addresses associated with the virtual router.

VirtualRouterUpTime

Specifies the time interval, in hundredths of a second, since the virtual router was initialized.

Action

Lists options to override the delay timer manually and force preemption:

  • none does not override the timer

  • preemptHoldDownTimer preempts the timer

HoldDownTimer

Configures the amount of time, in seconds, to wait before preempting the current VRRP primary router.

HoldDownState

Indicates the hold-down state of this VRRP interface. If the hold-down timer is operational, this variable is set to active; otherwise, this variable is set to dormant.

HoldDownTimeRemaining

Indicates the amount of time, in seconds, left before the HoldDownTimer expires.

CriticalIpAddr

Configures the critical IP address for VRRP.

This command specifies an IP interface on the local router, which is configured so that a change in its state causes a role switch in the virtual router (for example, from primary to backup) in case the interface stops responding.
Note:

In this context, local implies an address from the same VRF as the IP interface where VRRP is configured.

CriticalIpAddrEnable

Configures the IP interface on the local router to enable or disable the backup. The default is disabled.

BackUpMaster

Enables the backup VRRP system traffic forwarding. The default is disabled.

BackUpMasterState

Indicates whether the backup VRRP system traffic forwarding is enabled or disabled. The default is disabled.

FasterAdvInterval

Configures the Fast Advertisement Interval between sending VRRP advertisement messages. You must configure the same value on all participating routers. Enter the value in multiples of 200 milliseconds.

The default is 200.

FasterAdvIntervalEnable

Enables or disables the Fast Advertisement Interval. When disabled, the regular advertisement interval is used. The default is disable.

MasterHostname

Note:

Exception: not supported on VSP 4450 Series, VSP 8600 Series, or XA1400 Series.

Displays the SPBM host name of the VRRP primary router for a Distributed Virtual Routing (DvR) interface.

Origin

Note:

Exception: not supported on VSP 4450 Series, VSP 8600 Series, or XA1400 Series.

Displays how the VRRP interface was configured, either manually or via DvR.
