Configures the time between VRRP (Virtual Router Redundancy Protocol) advertisements in seconds or centiseconds.
| vlan_name |
Specifies the name of a VRRP VLAN (Virtual LAN). |
| vridval |
Specifies the VRID of a VRRP instance. To display the configured VRRP router instances, enter the show vrrp command. |
| interval |
Specifies an interval value for the time between advertisements. The range is 1 through 40 seconds or 10 through 4095 centiseconds. |
| seconds |
Specifies that the interval value is in seconds. If you do not specify seconds or centiseconds, the interval value is applied as seconds. |
| centiseconds |
Specifies that the interval value is in centiseconds. |
The advertisement interval is 1 second.
The advertisement interval specifies the interval between advertisements sent by the master router to inform the backup routers that its alive. You must use whole integers when configuring the advertisement interval.
An extremely busy CPU can create a short dual master situation. To avoid this, increase the advertisement interval.
Note
The milliseconds keyword is replaced by the centiseconds keyword, but the milliseconds keyword is still recognized to support existing configurations and scripts. Any values specified in milliseconds are converted to centiseconds. All new configurations and scripts should specify the interval in either seconds or centiseconds. The maximum value for an interval specified in seconds is 40. However, the software supports older configurations and scripts that specify values up to 255, which were supported prior to ExtremeXOS Release 12.7.
If you enter a number that is out of the seconds or centiseconds range, the switch displays an error message. For example, if the interval value is set to 999 and the centiseconds keyword is missing, the switch displays an error message similar to the following:
configure vrrp blue vrid 250 advertisement-interval 999 Error: Advertisement interval must be between 1 and 255 seconds. 999 out of rangeThe following command configures the advertisement interval for 15 seconds:
configure vrrp vlan vrrp-1 vrid 1 advertisement-interval 15
The following command configures the advertisement interval for 200 centiseconds:
configure vrrp vlan vrrp-1 vrid 1 advertisement-interval 200 centiseconds
This command was first available in ExtremeXOS 10.1.
The milliseconds and seconds keywords were added in ExtremeXOS 11.5.
The centiseconds keyword replaced the milliseconds keyword, and the maximum value for intervals specified in seconds was reduced to 40 in ExtremeXOS 12.7.
This command is available on platforms that support the appropriate license. For complete information about software licensing, including how to obtain and upgrade your license and which licenses support the VRRP feature, see the ExtremeXOS 22.7 Feature License Requirements document.
