GATEWAY FAIL-SAFE CONFIGURATION WITH TWO PARTITION AND TWO ROUTE DOMAIN

The first step of configuring the gateway fail-safe feature with route domains is to create two gateway pools in Common partition for each BIG-IP system in the device group. 

Run the commands on Active LB:

# Go to Common Partition:

cd /Common

# Create the pools ( Members are the gateways of each route domains on the partitions):

create ltm pool gateway_pool1 monitor gateway_icmp members add { 10.75.64.1%1:0 10.75.0.1%2:0 }

create ltm pool gateway_pool2 monitor gateway_icmp members add {10.75.64.1%1:0 10.75.0.1%2:0 }

# Assign the gateway pools to the corresponding units to which they are connected, since the pool information is synchronized between the systems:

modify ltm pool gateway_pool1 gateway-failsafe-device unit1

modify ltm pool gateway_pool2 gateway-failsafe-device unit2

# The minimum number of gateway pool members that must be available to avoid the designated action:

modify ltm pool gateway_pool1 min-up-members 2 min-up-members-action failover

modify ltm pool gateway_pool2 min-up-members 2 min-up-members-action failover

 # Enable the member status checking:

modify ltm pool gateway_pool1 min-up-members-checking enabled

modify ltm pool gateway_pool2 min-up-members-checking enabled

Save and sync the configuration to the standby device.
