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.
Set the delay timer on individual interfaces. The delay timer is supported on all physical interfaces, VLANs, and
LAGs.
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.
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.
