Specifying DHCP servers on a relay agent
To improve availability, you can specify several DHCP servers on the DHCP relay agent. When the interface receives request messages from clients, the relay agent forwards them to all DHCP servers.
Follow these guidelines when you specify a DHCP server address on a relay agent:
The IP address of any specified DHCP server must not reside on the same subnet as the IP address of the relay interface. Otherwise, the clients might fail to obtain IP addresses.
You can specify a maximum of eight DHCP servers.
