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

The
VIP address. The ServerIron ADX will continue to use the private IP address of the VIP for the local
site, if present.
The
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.
