3-DNS Controllers communicating with other 3-DNS Controllers
To allow 3-DNS Controllers to communicate with each other, you must
set up ssh and scp utilities.

To allow the 3-DNS Controller to communicate with BIG-IP systems
and EDGE-FX systems, you address the same ssh issues.
3-DNS Controllers communicating with big3d agents
◆
To allow communications between big3d agents and the 3-DNS
Controller, you need to configure iQuery ports on any 3-DNS
Controllers, BIG-IP systems, and EDGE-FX systems that run the big3d
agent.
The 3-DNS Controllers in your network need to communicate with each
other in order to synchronize configuration and performance data. If you use
exclusively crypto 3-DNS Controllers (those that use the SSH protocol) the
communication tools set up by the Setup utility are all you need.
If your network is a mixed environment, that is, composed of both crypto
and non-crypto systems, you need to enable the rsh and rcp utilities on the
crypto systems. Though the rsh and rcp utilities come pre-installed on the
crypto systems, you must explicitly enable these utilities. You can enable
the utilities using the Setup utility. Table 2.1 shows the ports and protocols
used for SSH and RSH communications between crypto and non-crypto
systems.

The big3d agent collects performance information from other 3-DNS
Controllers, BIG-IP systems, and EDGE-FX systems on behalf of the
3-DNS Controller you are configuring. The 3-DNS Controller then uses this
performance data for load balancing. The big3d agent uses factories to
manage the data collection. For detailed information on configuring the
