You have now set up the load balancing and delegation pools for your
domain. The last required configuration step is to create a topology
statement.
Adding a topology statement
The topology statement contains the topology records that the 3-DNS
Controller uses to load balance DNS queries from geographically dispersed
local DNS servers. The following procedure describes how to set up a
topology statement, with two topology records, for our example.
Note
For more detailed information on working with topology on the 3-DNS
Controller, see Chapter 3,
Topology , in the 3-DNS Reference Guide . For
information on setting up globally-distributed network with Topology load
balancing, see Chapter 6,
