Otherwise, the DHCP client cannot obtain a correct IPaddress.3.3.3 Correlating a DHCP Server Group with a Relay Agent InterfaceTo improve reliability, you can specify several DHCP servers as a group on the DHCPrelay agent and correlate a relay agent interface with the server group. When theinterface receives requesting messages from clients, the relay agent will forward themto all the DHCP servers of the group.Follow these steps to correlate a DHCP server group with a relay agent interface:
