DELL S6000-ON User Manual

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.

• When an interface comes up and becomes operational, the system waits 300 seconds (5 minutes) to 

bring up VRRP on that interface.

To set the delay time for VRRP initialization, use the following commands.

• Set the delay time for VRRP initialization on an individual interface.

INTERFACE mode

vrrp delay minimum seconds

This time is the gap between an interface coming up and being operational, and VRRP enabling.

The seconds range is from 0 to 900.

The default is 0.

• Set the delay time for VRRP initialization on all the interfaces in the system configured for VRRP.

INTERFACE mode

vrrp delay reload seconds

This time is the gap between system boot up completion and VRRP enabling.

The seconds range is from 0 to 900.

The default is 0.
