d. Configure the VRRP interface's DHCP server to use a custom gateway that corresponds to
one of the VRRP virtual IP addresses:
i. Click to expand DHCP Server > Advanced settings.
ii. For Gateway, select Custom.
iii. For Custom gateway, enter the IP address of one of the virtual IPs used by this VRRP
instance.
e. For backup devices, enable and configure SureLink on the VRRP interface. Generally, this
should be a LAN interface; VRRP+ will then monitor the LAN using SureLink to determine if
the interface has network connectivity and promote a backup to master if SureLink fails.
i. Click to expand IPv4 > SureLink.
ii. Click Enable.
iii. For Interval, type a the amount of time to wait between connectivity tests. To
guarantee seamless internet access for VRRP+ purposes, SureLink tests should occur
more often than the default of 15 minutes.
Allowed values are any number of weeks, days, hours, minutes, or seconds, and take
the format number{w|d|h|m|s}. For example, to set Interval to five seconds, enter 5s.
iv. Click to expand Test targets > Test target.
v. Configure the test target. For example, to configure SureLink to verify internet
connectivity on the LAN by pinging my.devicecloud.com:
ii. For Ping host, type my.devicecloud.com.
