You can specify the gateway IP address used as well as the health check method. The gateway address is defined under the GSLB Site slb-dev, and we tie that health check to a SLB Server object on the ADC. You may specify a different health check under the SLB Server object.
Here’re the configs:
!!! On the GSLB Controller
gslb site EAST
ip-server web3
ip-server web2
ip-server gw1
slb-dev dunn-adc-2 10.22.10.55
gateway 8.8.8.8
!!! On the local ADC
slb server external-gw 8.8.8.8
Successfully status:
dunn-adc-2-Standby-vBlade[2/2]#sh gslb slb-device
Attrs = Attributes, APF = Administrative Preference
Sesn-Num/Uzn = Number/Utilization of Available Sessions
GW = Gateway State, IPCnt = Count of Service-IPs
P = GSLB Protocol, L = Local Protocol
Device IP Attrs APF Sesn-Num Uzn GW IPCnt
