The sum of all the costs for all tracked interfaces must be less than or equal to the configured priority of the
VRRP group.

VRRP initialization delay
VRRP initialization delay is supported on the and z platforms.
When configured, VRRP is enabled immediately upon system reload or boot. VRRP initialization can be
delayed to allow IGP and EGP protocols to be enabled prior to selecting the VRRP Master. This delay
ensures that VRRP initializes with no errors or conflicts. The delay can be configured for up to 15 minutes,
after which VRRP enables normally.
The delay timer is set on individual interfaces and is supported on all physical interfaces, VLANS and
LAGs.
When both CLIs are configured, the later timer rules the VRRP enabling. For example, if
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.
