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.

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.
NOTE: When you reload a node that contains VRRP configuration and is enabled for VLT, Dell
Networking recommends that you configure the reload timer by using the
vrrp delay reload
command to ensure that VRRP is functional. Otherwise, when you reload a VLT node configured for
VRRP, the local destination address is not seen on the reloaded node causing suboptimal routing.
Set the delay timer on individual interfaces. The delay timer is supported on all physical interfaces, VLANs,
and LAGs.
When you configure both CLIs, the later timer rules VRRP enabling. For example, if you set vrrp delay
reload 600 and vrrp delay minimum 300, the following behavior occurs:
• When the system reloads, VRRP waits 600 seconds (10 minutes) to bring up VRRP on all interfaces
that are up and configured for VRRP.
