Dell C9000 Series Networking Configuration Manual page 1226

If you are configured for VRRP version 2, the timer values must be in multiples of whole seconds. For
example, timer value of 3 seconds or 300 centisecs are valid and equivalent. However, a timer value of 50
centisecs is invalid because it not is not multiple of 1 second.
If are using VRRP version 3, you must configure the timer values in multiples of 25 centisecs.
To change the advertisement interval in seconds or centisecs, use the following command. A centisecs is
1/100 of a second.
• Change the advertisement interval setting.
INTERFACE-VRID mode
advertise-interval seconds
The range is from 1 to 255 seconds.
The default is 1 second.
• For VRRPv3, change the advertisement centisecs interval setting.
INTERFACE-VRID mode
advertise-interval centisecs centisecs
The range is from 25 to 4075 centisecs in units of 25 centisecs.
The default is 100 centisecs.
Examples of the advertise-interval Command
The following example shows how to change the advertise interval using the advertise-interval
command.
Dell(conf-if-te-1/1/1)#vrrp-group 111
Dell(conf-if-te-1/1/1-vrid-111)#advertise-interval 10
Dell(conf-if-te-1/1/1-vrid-111)#
The following example shows how to verify the advertise interval change using the show conf command.
Dell(conf-if-te-1/1/1-vrid-111)#show conf

Setting VRRP Initialization Delay
When configured, VRRP is enabled immediately upon system reload or boot. You can delay VRRP initialization
to allow the IGP and EGP protocols to be enabled prior to selecting the VRRP Master. This delay ensures that
VRRP initializes with no errors or conflicts. You can configure the delay for up to 15 minutes, after which
VRRP enables normally.
