in the order they are configured in the software.
The global default values for the timeout, retransmit, and key optional
parameters are applied, unless those values are specified in the radius-server
host or other commands. To return to the global default values, if you configure
the timeout, retransmit, or key values, include those keywords when using the
no radius-server host command syntax.
You can use duplicate host names or IP addresses among RADIUS groups.

the default VRF.
