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.

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.
