8. Configure the VRRPinterface:

a. Configure the VRRPinterface's DHCPserver to use a custom gateway that correspondsto

oneof the VRRPvirtual IPaddresses:

i. Set the DHCPserver gateway typeto custom:

(config)> network interface eth2 ipv4 dhcp_server advanced gateway

custom

(config)>

ii. Determine the VRRPvirtual IPaddresses:

(config)> show network vrrp VRRP_test virtual_address

0 192.168.3.3

1 10.10.10.1

(config)>

iii. Set the custom gateway to one of the VRRPvirtual IP addresses. For example:

(config)> network interface eth2 ipv4 dhcp_server advanced

gateway_custom 192.168.3.3

(config)>

b. For backup devices, set the default gateway to the IPaddressof the VRRPinterface on the

master device. For example:

(config)> network interface eth2 ipv4 gateway 192.168.3.1

(config)>

c. For backup devices, enable and configure SureLink on the VRRPinterface.

i. Determine the VRRPinterface. Generally, this should be a LAN interface; VRRP+ will

then monitor the LAN using SureLink to determine if the interfacehas network

connectivity and promote a backup to master if SureLink fails.

(config)> show network vrrp VRRP_test interface

/network/interface/eth2

(config)>

ii. Enable SureLink on the interface:

(config)> network interface eth2 ipv4 surelink enable true

(config)>

iii. Set the amount of time to wait between connectivity tests:

(config)> network interface eth2 ipv4 surelink interval value

(config)>

where value is any number of weeks, days, hours, minutes, or seconds, and takes the

format number{w|d|h|m|s}.

For example, to set interval to ten minutes, enter 5s:
