Private VIPs for GSLB
1
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 ADX device, but
not for a local site (if present), by the ADX device itself, enter commands such as the following.
Virtual ADX-B#config t
Virtual ADX-B(config)#server virtual-name-or-ip dns-test 192.168.10.1
Virtual ADX-B(config-vs-dns-test)#gslb-ip 10.95.55.23 for-peer-only
Virtual ADX-B(config-vs-dns-test)#exit
To configure a public IP address for a VIP that will be used both by the peer GSLB ADX device and
locally, by the ADX device itself (if a local GSLB site is present), enter commands such as the
following.
Virtual ADX-B#config t
Virtual ADX-B(config)#server virtual-name-or-ip dns-test 192.168.10.1
Virtual ADX-B(config-vs-dns-test)#gslb-ip 10.95.55.23 for-self-and-peer
Virtual ADX-B(config-vs-dns-test)#exit
Note that these are the commands you would enter for the example shown in Figure 3 .
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 ADX device will use this public VIP
address. The ADX device 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 ADX device and the local ADX
device 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 ADX device, 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.
Private VIP display information
To obtain more information about the public and private IP addresses configured for a VIP on a
Brocade Virtual ADX, use the following commands:
• show gslb dns zone (see “Displaying the results of traffic distribution for Weighted IPs” on
page 40 for an example screen display)
• show gslb site (see “Displaying GSLB IP information” on page 28)
• show gslb dns detail (the following is an example)
For information about the field definitions for these commands, see the Brocade Virtual ADX.
Displaying GSLB IP information
You can view the GSLB IP address configuration for a VIP on a Brocade Virtual ADX. You can display
information about the public IP address for the Brocade Virtual ADX, to see whether the public IP
address is used by both the local and peer GSLB ADX devices, or by the peer GSLB ADX device only.
