NimbostratusHello,all.
I used to two virtual BIGIP that HA Lab, but fail,
the two BIGIP version is "BIG-IP 10.1.0 Build 3341.1084 Final "
BIGIP_1-------(HA mode Network Failover )--------BIGIP_2
HA mode Active-active
High Availability : Redundancy, unit 1 of BIGIP_1 device,unit 2 of BIGIP_2 device.
BIGIP_1: ConfigSync Peer Address set 198.18.19.252 ,BIGIP_1 management ip address is 192.168.0.105
BIGIP_2: ConfigSync Peer Address set 198.18.19.251 ,BIGIP_2 management ip address is 192.168.0.106
Detect ConfigSync Status enable
BIGIP_1: failover1|198.18.19.251|198.18.19.252|1026
failover2|192.168.0.105|192.168.0.106|1026
BIGIP_2: failover1|198.18.19.252|198.18.19.251|1026
failover2|192.168.0.106|192.168.0.105|1026
network mirroring:
BIGIP_1:Self _198.18.19.251,remote_198.18.19.252
BIGIP_2:Self _198.18.19.252,remote_198.18.19.251
High Availability-Fail_self--gateway:
add pool : failover_pool, pool member only include 198.18.19.1(default gateway),health moniter select "gateway_icmp"
ok, them can Synchronize configuration,but not switch over ,
down BIGIP_2 , BIGIP_1 can't take over BIGIP_1 's traffic .
b unit command on BIGIP_1 , display unit 1 :
[root@BIGIP_1:Active] config b unit
UNITS 1
reboot BIGIP_2, b failover standby command on BIGIP_2,and b unit command on BIGIP_1,dispaly:
[root@BIGIP_1:Active] config b unit
UNITS 1 and 2
but shutdown BIGIP_2,
[root@BIGIP:Active_] config b unit
UNITS 1 and 2
why ? ?

how kill this problem ? HA still does not work, switch to complete the normal process of proposed solutions or have you ideas?
Thanks !
