ServerIron ADX 1.1.1.102 is a GSLB ServerIron ADX that is providing GSLB for domain www.foo.com. One of the IP addresses for ww.foo.com is 2.1.1.23.
ServerIron ADX 2.1.1.103 and ServerIron ADX 2.1.1.104 are Site ServerIron ADXs. The GSLB ServerIron ADX and the Site ServerIron ADXs communicate using the GSLB protocol. ServerIron ADX 2.1.1.103 and ServerIron ADX 2.1.1.104 are in a high availability configuration. VIP 2.1.1.23 is configured on ServerIron ADXs 2.1.1.103 and 2.1.1.104.
On the GSLB ServerIron ADX, configure a HA group consisting of ServerIron ADX 2.1.1.103 and 2.1.1.104 as follows.
ServerIronADX# configure terminal
ServerIronADX(config)# gslb
ServerIronADX(config)# end
Next, associate an affinity definition for client (or client LDNS) network 2.1.1.0/24 with ServerIron ADX 2.1.1.104 on the GSLB ServerIron ADX as follows.
View the configured HA group using the following command.
Configured GSLB HA groups:
* GSLB HA group: {ServerIronADX 2.1.1.103, ServerIronADX 2.1.1.104}
Virtual IPs for ServerIronADX 2.1.1.103: 2.1.1.23(A)
Virtual IPs for ServerIronADX 2.1.1.104: 2.1.1.23(S)
In this example, VIP 2.1.1.23 is active (A) on ServerIron ADX 2.1.1.103 and standby (S) on ServerIron ADX 2.1.1.104.
