Correlating a DHCP server group with a relay agent interface
To improve reliability, you can specify several DHCP servers as a group on the DHCP relay agent and
correlate a relay agent interface with the server group. When the interface receives request messages
from clients, the relay agent will forward them to all the DHCP servers of the group.
Follow these steps to correlate a DHCP server group with a relay agent interface:
