Modify 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
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:
|
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:
|
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 through DvR. |
