Hi everyone,
I’m running a pair of Thunder ADC devices in active standby mode. Most of the time the failover works correctly, but sometimes the backup node doesn’t take over immediately when I simulate a failure. VIP remained inaccessible for approximately 20–30 seconds before traffic was restored.
I’ve checked the HA status and VRRP configuration but I’m not sure if this delay is occurring or if I’m missing a recommended setting.
Has anyone experienced something similar during production? Any suggestions on where to start troubleshooting would be appreciated.
