Private VIPs for GSLB

FIGURE 3
GSLB and private VIPs
Using the example in 
, suppose the configuration specifies that the public IP address will 
be used by both the peer GSLB ServerIron ADX A and the site ServerIron ADX B. If ServerIron ADX B 
is providing GSLB in addition to being a site ServerIron ADX, and has a local site configured, then it 
will also use this public IP address of the VIP for its local site.
 
Configuring a public IP address for a VIP
To configure a public IP address for a VIP that will be used only by the peer GSLB ServerIron ADX, 
but not for a local site (if present), by the ServerIron ADX itself, enter commands such as the 
following:
ServerIronADX-B# config t
ServerIronADX-B(config)# server virtual-name-or-ip dns-test 192.168.10.1
ServerIronADX-B(config-vs-dns-test)# gslb-ip 207.95.55.23 for-peer-only
ServerIronADX-B(config-vs-dns-test)# exit
To configure a public IP address for a VIP that will be used both by the peer GSLB ServerIron ADX 
and locally, by the ServerIron ADX itself (if a local GSLB site is present), enter commands such as 
the following: 
ServerIronADX-B# config t
ServerIronADX-B(config)# server virtual-name-or-ip dns-test 192.168.10.1
ServerIronADX-B(config-vs-dns-test)# gslb-ip 207.95.55.23 for-self-and-peer
ServerIronADX-B(config-vs-dns-test)# exit
Note that these are the commands you would enter for the example shown in 
.
Syntax:  gslb-ip <IP address> <for-peer-only | for-self-and-peer>
The <IP address> is the public IP address for the VIP.
The <for-peer-only> parameter specifies that only the peer GSLB ServerIron ADX will use this public 
VIP address. The ServerIron ADX will continue to use the private IP address of the VIP for the local 
site, if present.
The <for-self-and-peer> parameter specifies that both the peer GSLB ServerIron ADX and the local 
ServerIron ADX will use this public IP address for the VIP.
NOTE
Each time the mapping between the private IP address of the VIP and the public IP address changes, 
you need to reconfigure the new public IP address for the VIP on the ServerIron ADX, as well. Also, 
the GSLB IP addresses apply only to the GSLB feature. GSLB IP addresses do not affect any other 
feature nor are they used by any other feature.
