GSLB optimization

1. On controller, enable VIP list process optimization by issuing the following command at global
config level.
ServerIronADX(config)# gslb process-vip-list-optimize
ServerIronADX(config)# write memory
ServerIronADX(config)# reload
NOTE
A system reload is required after enabling the gslb process-vip-list-optimize command.
2. Under a site definition on the controller, add the si <si-ip-address> optimized-dist-hcheck
command.
ServerIronADX(config)# gslb site sunnyvale
ServerIronADX(config-gslb-site-sunnyvale)# si-name si-1 100.1.1.1
ServerIronADX(config-gslb-site-sunnyvale)# si 100.1.1.1 optimized-dist-hcheck
Syntax: [no] si <ip-address> optimized-dist-hcheck
The si <ip-address> optimized-dist-hcheck helps the controller identify the site that has the VIP
list process optimization enabled.
NOTE
on the GSLB controller (configured gslb process-vip-list-optimize
saved the configuration and reloaded the device), the message: "Please enable
hashing to optimize vip list processing and reload!"
will be displayed on
the GSLB controller SI when you configure this command on the Site SI and reload.
3. Issue the gslb send-vip-list-optimize command on the Site ServerIronADX.
Site-ServerIronADX(config)# gslb send-vip-list-optimize
Site-ServerIronADX(config)# write memory
Site-ServerIronADX(config)# reload
Syntax: [no] gslb send-vip-list-optimize
NOTE
A system reload is required after enabling this feature.

the site ServerIronADX from sending active binding information. Issue the following command.
Site-ServerIronADX(config)# gslb dont-send-active-bindings
Syntax: [no] gslb dont-send-active-bindings
