LTM Virtual Edition : set up redundant pair from a single device

LTM(LTM1) is running as a single device.

management : 192.168.10.154
external : 10.0.0.252/24
internal : 20.0.0.252/24

virtual server : 10.0.0.100   | external : 10.0.0.252 LTM1 --- management : 192.168.10.154   | internal : 20.0.0.252

I am going to set up redundant pair like this:

virtual server: 10.0.0.100          floating ip 10.0.0.254  |self ip 10.0.0.252     | self ip 10.0.0.253 LTM1               LTM2  | self ip 20.0.0.252     | self ip 20.0.0.253          floating ip : 20.0.0.254

Assumption
I already set up LTM1 settings ( self ip , virtual server , pool , node etc ) as a single device.

[ set up standby LTM ( LTM2 ) ]

configure hostname , self IP addresses , NTP server to adjust time.

Template and Wizards -> Device Wizards -> High Availability Setup Wizard

UNIT ID : 2
Network Failover : Network Failover


[ on LTM1 ]

Template and Wizards -> Device Wizards -> High Availability Setup Wizard

UNIT ID : 1
Network Failover : Network Failover

[ both LTM1 and LTM2 ]

configure floating IP addresses
Network -> Self IPs
check “floating IP”

configure VLAN fail safe
System -> High Availability -> Fail-safe -> VLAN

LEM1 is active and LTM2 is standby

[root@ltm-ve1:Active] config # bigpipe failover FAILOVER active for 0:58:50 [root@ltm-ve2:Standby] config # bigpipe failover FAILOVER standby for 0:58:38

[ sync configuration ( Virtual server , pool , node settings ) from LTM1 to LTM2 ]

on LTM1
System -> High Availability -> ConfigSync
Click “Synchronize to peer”

configuration was synchronized

[ access to Virtual server (10.0.0.100 ) from a client ]

When LTM1 is active and LTM2 is standby.

[root@ltm-ve1:Active] config # bigpipe failover FAILOVER active for 0:50:18 [root@ltm-ve2:Standby] config # bigpipe failover FAILOVER standby for 0:58:38

When LTM2 is active.

[root@ltm-ve2:Active] config # bigpipe failover FAILOVER active for 0:00:12 [root@ltm-ve1:Standby] config # bigpipe failover FAILOVER standby for 0:00:45
