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.

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.

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.
