Hello

I am trying to configure an A10 with 2 Internet Links to do response with a backup ip when gateway health check fails so I followed Multiple Gateway Links Configuration in the A10-GSLB.pdf but it´s not working

This is an example of my configuration:

gslb service-ip SIP-1 1.1.1.3  
health-check HTTPS  
&nbsp;port 443 tcp  
&nbsp;&nbsp;health-check HTTPS

gslb service-ip SIP-2 2.2.2.3

health-check HTTPS  
&nbsp;port 443 tcp  
&nbsp;&nbsp;health-check HTTPS

* * *

gslb site lab  
slb-dev LINK-1 1.1.1.2  
gateway 1.1.1.1  
vip-server SIP-1  
slb-dev LINK-2 2.2.2.2  
gateway 2.2.2.1  
vip-server SIP-2

* * *

gslb policy PCY-TEST  
&nbsp;metric-order health-check  
&nbsp;dns backup-alias  
&nbsp;dns server authoritative

* * *

gslb zone [test.com](http://test.com)  
policy PCY-TEST  
service 443 www  
&nbsp;&nbsp;dns-a-record SIP-1 ttl 30 static  
dns-a-record SIP-2 ttl 30 as-backup static

* * *

gslb protocol enable device  
!  
gslb protocol enable controller

So what a want to do is when LINK-1 failed the A10 response with SIP-2 and when I try it with the configuration above the site-1 gateway is down and site-1 status up but the resolution is still with the SIP-1 and not with SIP-2

Thanks!
