Setting VRRP Initialization Delay
VRRP initialization delay is supported on the S4820T platform.
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.
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.
Sample Configurations
Before you set up VRRP, review the following sample configurations.
VRRP for an IPv4 Configuration
The following configuration shows how to enable IPv4 VRRP. This example does not contain comprehensive directions
and is intended to provide guidance for only a typical VRRP configuration. You can copy and paste from the example to
your CLI. To support your own IP addresses, interfaces, names, and so on, be sure that you make the necessary
changes. The VRRP topology was created using the CLI configuration shown in the following example.
