Geographic region for a prefix
1
Syntax: [no] geo-prefix { <ipv4-prefix> | <ipv6-prefix>} [asia | europe | n-america | s-america |
africa]
The command configures an association between a prefix and a geographic location. The
<ipv4-prefix> and <ipv6-prefix> variables identify the respective networks. Five operands serve as
location tags for the network: asia, europe, n-america, s-america, and africa.
NOTE
When a geographic prefix is converted from static to dynamic through geographic prefix
configuration, the old geographic prefix information will be replaced with the new information. If the
prefix is deleted, the old value will not be restored because it has already been replaced.
Displaying the number of geographic prefixes
To view the number of geographic prefixes defined on a GSLB ServerIron ADX, enter the following
command.
GSLB-ServerIronADX# show gslb resources
GSLB resource usage:

Current Maximum

sites 2 128

ServerIronADXs 0 256

ServerIronADXs' VIPs 0 2048

dns zones 1 256

dns hosts 1 1024

health-checks app. 1 1024

dns IP addrs. 0 2048

affinities 0 128

static prefixes 0 250

user geo prefixes 1 64

prefix cache 109 10128

RTT entries 0 20000

GSLB host policies 0 100
The “Current” column for user geo prefixes specifies the number of user-configured geographic
prefixes. The "Maximum” column denotes the maximum number of geographic prefixes that you
can configure. In the example above, there is one configured geographic prefix, and a maximum of
64 configurable geographic prefixes can be specified on the GSLB ServerIron ADX.
Syntax: show gslb resources
Displaying information about geographic prefix
To view information about a specific geographic prefix, enter the following command on the GSLB
ServerIron ADX.
GSLB-ServerIronADX# show gslb cache 24.192.0.0
prefix length = 24, prefix = 24.192.0.0, region = EUROPE

prefix source = geographic (user-configured)
The output above shows the IP address prefix, prefix length, the geographic region and source (in
this case it is a user-configured geographic prefix entry. For more examples, refer to
“Displaying RTT
information” on page 178.
Syntax: show gslb cache <IP address prefix>
