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

In the navigation pane, expand the following folders: Configuration > IP.
Click VRRP.
Click the Interface tab.
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.
In the Action check box, select an option.
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 5320 Series or 5420 Series.	Displays the SPBM host name of the VRRP primary router for a Distributed Virtual Routing (DvR) interface.
Origin Note: Exception: not supported on 5320 Series or 5420 Series.	Displays how the VRRP interface was configured, either manually or via DvR.
